An aftermarket component designed to replace the factory air intake system in a specific model year of a Subaru WRX. Its purpose is to improve engine performance by providing a less restrictive path for air to enter the engine, potentially leading to increased horsepower and torque. For example, a 2017 WRX might experience improved throttle response after the installation of such a system.
The perceived advantages of this modification often stem from the premise that cooler, denser air contains more oxygen, theoretically enhancing the combustion process within the engine. This can result in improved engine efficiency and power output. Historically, enthusiasts have sought such enhancements to personalize and optimize their vehicles’ performance characteristics, particularly in models renowned for their turbocharged engines.
Subsequent sections will delve into the specific benefits, potential drawbacks, installation considerations, and maintenance requirements associated with upgrading the air intake system in a 2017 WRX, providing a detailed analysis for prospective users.
1. Increased Airflow
The allure of enhanced performance for the 2017 WRX often begins with the promise of greater airflow. The factory air intake system, designed for a balance of performance, noise reduction, and cost-effectiveness, can present a bottleneck to the turbocharged engine’s potential. Aftermarket intakes, specifically designed for the 2017 WRX, aim to remove this restriction, allowing the engine to breathe more freely. The principle is simple: more air, combined with appropriate fuel delivery, should yield more power. The increased airflow provides the foundation on which other performance enhancements can build. Without this fundamental improvement, gains from other modifications may be limited.
Consider a scenario where a 2017 WRX owner installs a larger turbocharger, aiming for a significant horsepower increase. If the factory air intake remains in place, the turbocharger’s potential will be choked off by the limited airflow. In this situation, an aftermarket intake acts as a necessary enabler, providing the larger turbocharger with the volume of air it requires to operate efficiently. Similarly, an owner seeking improved throttle response on the street might find that a less restrictive intake provides a noticeable improvement in the engine’s willingness to rev, offering a more engaging driving experience.
In essence, the relationship is causal. Installing an aftermarket intake on a 2017 WRX can increase airflow. This increase, in turn, can enable the engine to produce more power, improve throttle response, and potentially enhance overall performance. It’s a foundational element in the pursuit of performance gains, but it’s crucial to remember that this modification exists within a larger ecosystem of factors, including fuel delivery, engine tuning, and overall vehicle condition. While increased airflow is a key component, realizing its full potential requires careful consideration of the entire performance equation.
2. Improved Horsepower
The promise of amplified power is a siren song for many 2017 WRX owners. It is a simple equation in the minds of many: a freer-flowing air intake translates directly to more horsepower. The reality, however, is a more nuanced narrative. While the installation of an aftermarket intake on a 2017 WRX can contribute to a horsepower increase, it is rarely a standalone solution. Think of it as a single instrument in an orchestra. A trumpet, no matter how skilled the musician, cannot carry the entire symphony alone. Similarly, the intake’s impact is contingent upon other factors, such as the engine’s state of tune, the presence of other performance modifications, and even the prevailing environmental conditions.
Consider the tale of two identical 2017 WRXs. One, bone stock except for the aftermarket intake, sees a marginal gain on the dyno perhaps 5-7 horsepower at peak. Noticeable? Perhaps, but hardly transformative. The second, however, benefits from a professional ECU tune tailored to the intake, along with a less restrictive exhaust system. This WRX yields a far more impressive result, pushing 20-30 horsepower gains. The difference lies not in the intake itself, but in the synergy created with other complementary upgrades and, crucially, the recalibration of the engine’s control unit to take full advantage of the increased airflow. The intake, in this scenario, becomes a catalyst, unlocking hidden potential within the engine, but only when paired with the right supporting cast.
Therefore, improved horsepower, in the context of the 2017 WRX and an aftermarket intake, should be viewed as a potential outcome, not a guaranteed certainty. The practical significance of this understanding lies in managing expectations and making informed decisions. Simply bolting on an intake and hoping for a dramatic power surge is often a recipe for disappointment. However, strategically incorporating the intake into a well-planned suite of modifications, coupled with a professional tune, can indeed yield a tangible and satisfying increase in horsepower, transforming the driving experience. The key is to remember that the intake is but one piece of the puzzle, not the entire picture.
3. Enhanced Sound
The aural character of a vehicle, particularly one with sporting intentions like the 2017 WRX, holds a significant place in the ownership experience. The installation of a cold air intake often alters this soundscape, moving the engine’s voice from a muffled murmur to a more pronounced and assertive tone. This shift is not merely superficial; it speaks to a deeper connection between driver and machine, providing auditory feedback that can enhance the sense of performance and engagement. The whoosh of the turbocharger spooling, the deeper growl under acceleration these are not just noises, but signals of mechanical activity translating into forward motion. For some drivers, this added auditory dimension is a key component of the upgrade, a tangible reminder of the enhanced performance.
The effect, however, is not uniform. The specific sound profile resulting from a cold air intake varies depending on the design of the intake itself, the materials used in its construction, and even the individual engine’s characteristics. Some intakes produce a subtle increase in sound, barely perceptible over the stock system, while others create a far more dramatic transformation. The choice, therefore, becomes a matter of personal preference. An individual who values a refined driving experience may opt for a more subdued intake, while someone seeking a bolder and more visceral sensation might choose one known for its aggressive sound. Consider the case of a 2017 WRX owner who installed an intake known for its pronounced turbo whistle. While they appreciated the increased performance, the constant whistling became grating during long commutes, leading them to eventually switch to a quieter intake.
Ultimately, the enhanced sound associated with a cold air intake is a subjective element, a flavoring added to the driving experience. It is a feature that should be carefully considered, weighed against individual preferences and driving habits. While performance gains are quantifiable, the auditory impact is more personal, a matter of how the driver perceives and interacts with their machine. The prudent owner will research the sound profiles of different intakes, listen to examples online, and, if possible, experience them firsthand before making a decision. The goal is to find an intake that not only improves performance but also enhances the driving experience in a way that aligns with their individual tastes and expectations.
4. Installation Complexity
The narrative of modifying a 2017 WRX often encounters the chapter of installation complexity, a pivotal point where ambition meets practicality. The allure of enhanced performance, promised by the aftermarket intake, can quickly fade when faced with the realities of wrenches, unfamiliar parts, and the looming threat of a misstep. The relationship between the component and the task is direct: the more intricate the intake’s design, the greater the potential for complications during installation. Consider the stock intake system, typically designed for ease of assembly at the factory; replacement with an aftermarket variant can introduce nuances not immediately apparent. An ill-fitting coupler, a misplaced sensor, or even a simple oversight in tightening a clamp can negate any performance gains and introduce unforeseen issues. The complexity, therefore, is not merely a matter of physical dexterity but also of comprehension and attention to detail.
The experience of a 2017 WRX owner in a small town garage illustrates this point vividly. Armed with online tutorials and a new intake promising significant horsepower gains, the owner embarked on the installation. However, the tutorial glossed over a subtle difference in the sensor mounting bracket between the stock and aftermarket intakes. Hours were lost trying to force the sensor into a space it was never meant to occupy, ultimately leading to a cracked sensor housing. The promised horsepower gains were replaced by a check engine light and a costly trip to a mechanic. This anecdote underscores a crucial lesson: the complexity of the installation is not solely determined by the component itself but also by the installer’s skill and understanding. A seemingly straightforward task can quickly become a source of frustration and expense if approached without proper preparation and diligence.

Understanding and respecting this complexity is the key to a successful modification and a more satisfying driving experience.
5. Filter Maintenance
The lifeblood of a 2017 WRX equipped with a cold air intake flows, quite literally, through its filter. This component, often overlooked in the initial excitement of performance gains, stands as a sentinel, protecting the engine from the abrasive onslaught of airborne contaminants. A neglected filter is a betrayal of the intake’s purpose, a slow erosion of the performance gains it promised. The connection between the intake and the filter is symbiotic; one cannot thrive without the proper care of the other. Think of the filter as the lungs of the engine, breathing in air but diligently trapping dust, pollen, and debris. As these particles accumulate, they choke the filter, restricting airflow and gradually diminishing the engine’s ability to breathe freely. The promised horsepower increase fades, replaced by sluggish performance and a potential decrease in fuel economy. The consequences of neglecting filter maintenance can extend beyond mere performance degradation. A severely clogged filter can cause the engine to work harder, increasing stress on other components and potentially leading to premature wear and tear.
Consider the case of a 2017 WRX owner who, after installing a high-performance intake, failed to adhere to the recommended filter maintenance schedule. The owner, consumed by the thrill of increased throttle response, neglected to clean or replace the filter for an extended period. Over time, the filter became saturated with dirt and grime, severely restricting airflow. The engine, starved for air, began to misfire, and fuel economy plummeted. Eventually, the owner was forced to seek professional assistance, only to discover that the neglected filter had contributed to carbon buildup on the intake valves, requiring costly repairs. This narrative serves as a cautionary tale, highlighting the importance of diligent filter maintenance as an integral part of owning and operating a WRX with an aftermarket intake. The choice is simple: invest time in cleaning or replacing the filter, or risk facing more significant and expensive problems down the road. The filter, in its humble role, safeguards the engine’s health and sustains the performance enhancements sought after the intake installation.
In summary, the filter is not merely an accessory to the cold air intake of a 2017 WRX; it is its guardian, its protector, and its silent partner in performance.

The tale of the neglected filter serves as a stark reminder: the pursuit of enhanced performance must be tempered with responsibility and a commitment to maintaining the components that make it possible. The filter, in its simplicity, holds the key to unlocking and sustaining the true potential of the 2017 WRXs aftermarket air intake system.
6. ECU Calibration
The electronic control unit, or ECU, serves as the brain of the 2017 WRX, dictating the engine’s operation with precision. When an aftermarket cold air intake replaces the factory system, the ECU’s pre-programmed instructions may no longer align perfectly with the engine’s new breathing characteristics. This misalignment necessitates recalibration a fine-tuning of the ECU’s parameters to optimize performance and prevent potential complications. The relationship is not merely correlational, but causal. A cold air intake alters the airflow dynamics. The ECU, unaware of this change, continues to operate based on outdated assumptions. Recalibration bridges this gap, ensuring harmonious operation.
-
Fuel Trim Adjustments
The ECU constantly monitors and adjusts the air-fuel ratio, aiming for an ideal balance. A cold air intake can alter the airflow, potentially leaning out the mixture (too much air, not enough fuel). ECU recalibration involves adjusting the fuel trims, adding fuel where needed to maintain the optimal ratio. Imagine a chef following a recipe with slightly different ingredients. He or she must adjust the quantities to achieve the desired outcome. Similarly, the ECU, with recalibration, compensates for the altered airflow to ensure proper combustion. Failing to do so can lead to decreased performance, increased engine temperature, and even potential engine damage.
-
Ignition Timing Optimization
Ignition timing dictates when the spark plugs fire, igniting the air-fuel mixture. Recalibration allows for optimizing the timing to take advantage of the increased airflow. Advancing the timing (firing the spark plugs slightly earlier) can extract more power, but only if the engine can handle it without knocking or pinging. Think of it as fine-tuning the stroke of a hammer. Too early, and the impact is weak; too late, and the force is misdirected. The ECU, with recalibration, finds the optimal timing to maximize power without risking damage. A common scenario involves a 2017 WRX owner installing an intake and experiencing a slight increase in power, but also increased knock. Recalibration addresses this issue by subtly retarding the timing in certain areas, sacrificing a small amount of potential power to ensure long-term engine health.
-
MAF Sensor Scaling
The mass airflow (MAF) sensor measures the amount of air entering the engine. Aftermarket intakes can alter the airflow path near the sensor, skewing its readings. ECU recalibration involves scaling the MAF sensor, telling the ECU how to interpret the sensor’s output correctly. It is akin to translating measurements from one system to another. If the ECU thinks it is receiving one liter of air when it is actually receiving 1.1 liters, it will under-fuel, leading to a lean condition. MAF scaling corrects this discrepancy, ensuring accurate air-fuel calculations. A common misconception is that aftermarket intakes are “plug and play.” While some may function adequately without recalibration, optimal performance and long-term engine health require proper MAF scaling.
-
Boost Control Refinement
The 2017 WRX utilizes a turbocharger to force more air into the engine. Aftermarket intakes, by reducing intake restriction, can subtly alter the turbocharger’s behavior. ECU recalibration allows for refining the boost control strategy, ensuring stable and predictable boost levels. It is similar to fine-tuning the pressure regulator on a scuba tank. Too much pressure, and the diver risks injury; too little, and the diver cannot breathe properly. The ECU, with recalibration, maintains consistent boost levels, optimizing power delivery and preventing overboost situations. An owner might install an intake and notice inconsistent boost pressure, fluctuating under heavy acceleration. Recalibration corrects this by adjusting the wastegate duty cycle, stabilizing the boost and ensuring smooth power delivery.
These facets illustrate that recalibration is not a mere suggestion, but a critical step in integrating an aftermarket intake into a 2017 WRX. Failure to recalibrate can lead to suboptimal performance, potential engine damage, and a missed opportunity to unlock the intake’s true potential. The relationship between the intake and the ECU is a partnership, and recalibration is the key to ensuring that partnership functions harmoniously.
7. Potential Drawbacks
The pursuit of enhanced performance for a 2017 WRX through the installation of a cold air intake is often viewed through a lens of potential gains.

-
Reduced Low-End Torque
The very design of some aftermarket intakes, optimized for high-RPM airflow, can inadvertently sacrifice low-end torque, the pulling power felt during everyday driving. The factory intake, while restrictive at higher RPMs, is often engineered to maintain optimal airflow at lower speeds. An aftermarket intake, with its larger diameter and straighter flow path, can sometimes disrupt this balance, leading to a noticeable decrease in torque during off-the-line acceleration. Imagine navigating city traffic in a 2017 WRX, requiring frequent bursts of acceleration to merge or change lanes. The reduced low-end torque could make the car feel sluggish and less responsive, negating the perceived benefits of increased horsepower at higher RPMs. This trade-off, often unspoken, is a critical factor for drivers who prioritize daily drivability over peak performance on a track.
-
Increased Engine Noise
While the enhanced sound of a cold air intake is often touted as a benefit, the reality can be less appealing for some drivers. The increased engine noise, particularly at higher RPMs, can become intrusive and fatiguing during long journeys. The throaty growl that is exhilarating during a weekend drive can transform into a droning resonance that grates on the nerves during a daily commute. Consider a 2017 WRX owner who regularly undertakes long highway trips. The constant engine noise, amplified by the aftermarket intake, could contribute to driver fatigue and reduced overall comfort, diminishing the enjoyment of the vehicle. This underscores the subjective nature of the “enhanced sound” benefit, highlighting the need for careful consideration of individual preferences and driving habits.
-
Potential for Hydro-Locking
Some cold air intake designs, particularly those that position the air filter low in the engine bay, increase the risk of hydro-locking, a catastrophic engine failure caused by water entering the cylinders. In heavy rain or during fording shallow water, the low-mounted filter can become submerged, sucking water into the engine. Water, being incompressible, can cause severe damage to the pistons, connecting rods, and crankshaft. Visualize a 2017 WRX owner driving through a flooded street after a sudden downpour. The low-mounted intake, unbeknownst to the driver, ingests a significant amount of water, causing the engine to seize within seconds. The resulting damage could cost thousands of dollars to repair, turning a minor inconvenience into a financial disaster. This risk, while not present in all intake designs, warrants careful consideration, particularly for drivers who live in areas prone to heavy rainfall or flooding. Opting for an intake with a higher filter placement or a bypass valve can mitigate this risk, but at the expense of some performance gains.
-
Compromised Air Filtration
Certain aftermarket air filters, striving for maximum airflow, may compromise the level of air filtration compared to the factory filter. While increased airflow can improve engine performance, it also allows larger particles to pass through the filter and enter the engine. Over time, these particles can cause wear and tear on critical engine components, such as the cylinder walls, piston rings, and valves. Imagine a 2017 WRX owner who frequently drives on dusty or gravel roads. The less restrictive filter of their aftermarket intake allows a greater amount of fine dust to enter the engine, gradually eroding the cylinder walls and reducing compression. This accelerated wear could shorten the engine’s lifespan and lead to costly repairs down the road. The trade-off between airflow and filtration efficiency is a crucial consideration, particularly for drivers who operate their vehicles in harsh environments. Choosing a high-quality filter with a balance of airflow and filtration capabilities can mitigate this risk, but requires careful research and selection.
These potential drawbacks illustrate the importance of informed decision-making when considering an aftermarket intake for a 2017 WRX.
