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

  Although I have rated the product high, the installation instructions had a few hitches. (1) The air pump that was illustrated in the instructions did not look like the pump on the 2015. The pump would not fit in the specified location until I realized the the external hood had to be removed. (2) The hose leading to the pump require trimming a few inches at the pump end to eliminate kinking...not mentioned in the instructions.

  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.

  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.
