The K&N 63-9031-1 Air Intake fits some Toyota Sequoia, and Toyota Tundra models. See vehicle applications link for details.
The K&N AirCharger 63-9031-1 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’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 63-9031-1 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 requiring only a screwdriver, 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 63-9031-1 Air Intake Product Reviews

Friday, November 4, 2016 - Part 63-9031-1
Noticeable improvement in throttle response and performance at take off. Pulls hard through all shifts. Great sound improvement with existing TRD dual exhaust. Mileage increased 1.8 mpg, might be more if I could keep off the throttle. Easy install, everything was as advertised. Very happy and highly recommend.

The instructions were not to clear on some of the installation. However, once past that I noticed an increase in fuel economy. I went from 14.4mpg to 15.5mpg. Not much but something. Has a great sound when you get the rpm's up. I am getting a K&N for my car now, I love it.

The product was shipped really fast. I am not a mechanic and the intake system was not hard at all to install. It took me about 1hr & 45m total. My truck sounds great I really recommend this product. If I ever get a new truck I will purchase an intake system again.
