The K&N 63-9036 Air Intake fits some Toyota Tundra models. See vehicle applications link for details.
The K&N AirCharger 63-9036 air intake system replaces the restrictive factory air filter and air intake housing in some Toyota Tundra models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Tundra’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 63-9036 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.

As far as the process of getting it, it went smooth and arrived when it said it would. But as far as performance it did not do anything or really make any difference.

My second K&N air intake and I love it more than my first one. I installed in about 1 hr 45 minutes on my 2017 Toyota Tundra SR5. The sound is mean and the response is everything I expected. Will buy K&N for any future vehicles I have. I even convinced my friend to buy one for his 2014 Jeep Wrangelr and we installed on same day. He fell in love like I did the first K&N around.

Really nice add on. Sounds great, looks nice, and gives a noticeable increase in performance. I did dual exhaust at the same time, I mean if you're going to uncork the front end you might as well do the back as well. I love K&N intakes. By the way, thanks for the hat guys, we like them. My buddy had to get an intake for his truck too after seeing mine. I drive up a mountain pass 4-5 times a week to Tahoe for work and play, I notice the performance best on those drives.

Easy to install, and you can tell a difference in the performance.

Great product, quick install. Would mount the brackets first to truck before the filter housing. At least the one that shares the horn mount. Easily get 17 mpg at 65 mph and almost 20 mpg going 60 mph on average. Great with the exhaust sound. Will pay for itself by a couple of oil changes.

Installed this on my new 2016 Tundra limited 4x4. Installation was easy and the sound it produces is freakin sweet. The power is good and mileage is improved slightly, but that's not what I got it for.

Super easy to install, sounds great. Not sure I gained much horse power, and after driving for a month, I picked up about a mile per gallon. My install was on a 2014 Tundra 4x4. I would recommend to anyone wanting to maintain factory warranties, while adding a throatier sound and a little power.
