The K&N AirCharger 63-9037 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 63-9037 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that mounts onto the inner fender. This allows cooler, denser air to be directed 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 using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Product Reviews


  Well, so far this has been a super easy experience. The K&N site made it super easy to find the CAI for my truck, the shipping was fast, and everything arrived ready to go. Finally got to installing the CAI this afternoon, and while it's easy, the directions provided and photos within those directions made for an excellent experience. I found the directions extremely accurate and easy to understand and follow. While I didn't time it, the install did take the suggested 90 minutes, or so.

  Best intake system ever!!

  2013 Tacoma 4.0L V6. Install took me longer than expected but was due to my own fault, relocating the secondary air pump was the culprit. Other than that this CAI works! After two weeks of normal driving I saw slight mpg increase (1-1.5?) but I can't seem to keep my foot out of the gas cause it roars when I have to get on it! No more gas pedal hesitation thanks to K&N! I'm a lifer now!

  Great instructions. About 2 hours in the driveway. Great intake sound. slight increase in gas mileage. Feelable power above 3000 rpm''s.

  Product was received well packaged and protected with all the necessary hardware enclosed. Instructions were very clear and pictures were very helpful as well. This is my second installation I've done on my second vehicle. Even with overall clear instructions, thought and patience must be used as the instructions do not point out all the little nuances that will be encountered. On this latest install I wondered if there may have been a better way of remounting or relocating an item or two. If anyone is thinking about purchasing this system, you cannot go wrong and will not be disappointed. The quality and workmanship of this unit is built to last and I would endorse it again and again.
