The K&N 57-9020 Air Intake fits some Toyota Sequoia, and Toyota Tundra models. See vehicle applications link for details.
The K&N 57-9020 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Toyota Tundra and Sequoia models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57-9020 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and 3 replacement silicone engine vent lines. The oversized cone shaped 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 usually in 90 minutes or less using the existing factory mounting points requiring commonly available tools to do the job. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

I have always used K&N cold air intake kits on my truck. I have always been impressed with the results. My Tundra has better sound, better throttle response, and though K&N doesn't brag about it, I have gotten noticeable better gas mileage on my 02 Tundra 4.7L.. My other trucks I didn't notice much in the way of gas mileage. I always stand by K&N and their great products. Thank you.

Bought a used 2003 Toyota Sequoia in 2011. Love the SUV and the engine but the lag-time from the moment I step on the gas until the engine responds was terrible (As in quickly passing a car)! All my cars have K&N air filters but this was the first Intake kit and boy was it worth it! There's almost no lag-time anymore and it's a pleasing sound coming from the engine as the Toyota accelerates quickly. Don't think I can actually feel a difference as far as gaining 13 hp but then the engine is very adequate already.

I am giving 5 stars because I received the intake kit on time and the installation was easy. I have not yet analyzed the effect on my MPG, but noticed a definite improvement in throttle response.

The intake kit was exactly as advertised. The instructions were clear and easy to follow and there were no surprises or extras involved. I am completely satisfied with the product and service.

The Performance intake kit was easy to install with no special tools. The performance increase was noticeable and I love the way it sounds. I'm glad I did this, I wish I had done it sooner.
