A specialized aftermarket accessory designed for the Honda Foreman 520 all-terrain vehicle, this component elevates the engine’s air intake and CVT (Continuously Variable Transmission) inlets, and sometimes the vent lines, to a higher position. This modification allows the ATV to navigate deeper water and muddy terrain without water entering and potentially damaging critical engine and transmission components. The elevated inlets are typically achieved through the use of rigid PVC or flexible rubber tubing, secured with clamps, and routed to a point above the vehicle’s typical operating water line.
The principal advantage lies in enhanced protection against water ingestion, a significant concern for ATV users operating in wet or submerged environments. By preventing water from entering the engine, this setup mitigates the risk of hydrolock, a catastrophic engine failure caused by incompressible water filling the cylinder. Similarly, keeping the CVT system dry prevents belt slippage and ensures consistent power delivery. Historically, owners have fabricated their own solutions; however, commercially available kits offer a more robust, engineered, and often aesthetically pleasing alternative.
