Performance Air Intake for 2005 to 2008 Toyota 4Runner
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.
is simple and can be done without drilling or cutting. Each K&N 77- Series Kit
comes complete with all necessary hardware, including die-cast aluminum sensor
