The 63-1120 replaces the stock airbox and intake track. An oversized K&N X-Stream Top air filter is included to increase airflow along with dirt and dust capacity. K&N’s unique pleated design provides a larger surface area and an increased volume of air flow over the stock unit. This results in better throttle response, additional horsepower and longer service intervals.

The airbox is made of black powder-coated steel to protect the K&N X-Stream Top Air Filter from pulling in engine heated air. A separate crankcase breather filter vents heat and oil vapor generated from engine crank pressure. A K&N DryCharger is supplied for extreme dust or wet conditions.

For optimum performance, fuel management modifications are not necessary. K&N high-flow air filters are washable and reusable. They allow high air flow while providing excellent filtration. Most K&N air intakes can be installed in 90 minutes or less.

The K&N 63-1120 air intake fits the following Polaris models:

The 57-3515 was engineered to work within the Ridgeline’s computer specifications while maximizing power and at the same time, allowing air to flow with little restriction. The aerodynamically engineered tube allows virtually free flowing air into the 3.5 liter engine for an immediate power gain.

K&N engineers also used the factory fresh air duct on the 2006 Honda Ridgeline. The factory fresh air inlet in the bottom of the engine compartment guides cool outside air into the intake track.

The powder coated steel heat shield has an opening that allows the fresh air intake duct to feed air to the K&N chrome top air filter (RC-4760). The K&N washable and reusable air filter is also isolated from high engine temperatures by the heat shield which also contributes to the increase in horsepower.

Backed by the famous K&N Million Mile Limited Warranty it takes 90 minutes or less to install the 57-3515 with simple hand tools.
