The K&N 63-9037 Air Intake fits some Toyota Tacoma models. See vehicle applications link for details.
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.

K&N 63-9037 Air Intake Product Reviews

I purchased this intake for 2013 tacoma, only draw back are printed install directions. However, works great, sounds great. Louder than stock but very tolerable. I did not test yet it feels a little more peppy, over all I recommend this product. Go for it.

The directions were vague in telling you which bolts to use. It just says use the provided hardware. YouTube videos helped a lot with this install. It takes about an hour and you need someone else for about one minute to hold a bolt from underneath. I really like the sound my engine makes now and I did get at least one mpg improvement on the highway.

This the best upgrade you can do for the price. It is a very good investment it increased the horsepower and my mpg. with the stock air intake I use to get around 22mpg and now I get around 26-28 mpg.

Sounds great on my Tacoma. More power and a little bit better mileage. The instructions were not even close to accurate. Need better descriptions and photos. All around it is a great product.

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.
