The K&N AirCharger 63-9025 air intake system replaces the restrictive factory air filter and air intake housing in some Toyota Tacoma models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Tacoma’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-9025 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that directs cooler, denser air through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only two screwdrivers, a socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

  • K&N’s easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow
  • This power gaining air intake comes with K&N’s famous million mile limited warranty

  • Alan V Solarino

    Made a noticeable difference I gained around 2 more miles to the Gallon and my tacoma truly sounds like a beast when it hits the high rpm! Not a major gain in speed but It does seem like it’s quicker off the start and goes up hills much easier! Most definitely would buy again if I had another tacoma

  • Peter Daigle

    This product is like switching from orange juice to red bull. It not only makes my tacoma sound like a beefy V8 but also I’m getting a lot better fuel economy. Truck gets up to speed faster, and transmission shifts quickly and smoother. For the price, it is definitely worth it.

  • Bradley Stemper

    The throttle feels more responsive, but really the added speed and performance benefits are minimal. It sounds bad ass, feels bad ass, and it easy to install (YouTube+directions= 1/2 hour job)
