The K&N 57-9015-1 FIPK 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 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 57-9015-1 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 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 and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-9015-1 Air Intake Product Reviews

Tuesday, June 7, 2016 - Part 57-9015-1
Intake kit arrived very quickly, even with standard ground shipping. The kit went on great, but took me much longer than 90 minutes. I'm not much of a gear head, so I took my time and read instructions and identified the location of all the parts several times. Plus I needed to clean out the engine compartment after I removed the old and very dirty air system. Looks and runs great. Really not much difference in sound except when going up hills. Seems to have more power and got a increase of 1.5 mpg with mostly highway driving.

I haven't had a chance to install it yet, but I know I'll love it!

Installation was straight forward. The only thing that was not clear was that the spacers were needed to install one of the airflow sensors. I figured it out at the end when I had four spacers extra in the install kit. I would not believe it if someone told me that you can actually feel the difference in performance with a simple intake air kit. I already knew because I had one installed in my Suburban and you can really feel more torque. Same way happened with this kit in my 2001 Toyota 4Runner.

Just bought a 2004 Toyota Tacoma and installed the cold air intake and I feel that it gives a little more horse power and love the way it sounds. Not really a gas saver when you drive well over the speed limits though. I definitely would purchase another for my next Toyota.
