K&N 03-08 Toyota 4Runner V6-4.0L Aircharger Performance Intake

Take your Toyota 4Runner to the next level with the K&N Aircharger 63-9023 air intake system. This high-performance intake replaces the restrictive factory air filter and air intake housing, allowing for virtually unrestricted airflow.

With a chrome-topped K&N high-flow air filter and a heat shield that mounts onto the inner fender, this intake system directs cooler, denser air through a custom-molded intake tube into the engine's throttle body for a guaranteed power gain.

  • Lasts up to 100,000 miles before service required
  • Estimated horsepower gain: 9.23 HP @ 5388 RPM
  • Easy to install with basic tools
