Designed to improve airflow to the engine, testing on K&N's dynamometer showed a 7.38 horsepower gain @ 5270 RPM. "The mandrel-bent, free flowing, one-piece polished aluminum tube will mount to the throttle body," said K&N Peformance Kit Technical Development Supervisor Kirk Swanson. "The K&N Kit (77-9029KP) goes over to the fender well and mounts to the filter on the other end."

A steel heatshield, finished in black powdercoat isolates the filter from ambient underhood heat to supply the engine with cooler denser air. The 77 Series polished intake tube (77-9029KP) is coupled to the OE components with reinforced silicone hose to absorb engine vibrations. Stainless-steel hose clamps secure parts to one another and black powdercoated steel brackets add additional support.

K&N's High Flow Replacement filter (RF-1048) provides optimal air flow and is backed by K&N's Famous Million Mile Warranty.
