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

Thursday, September 27, 2018 - Part 57-9015-1
I am over all happy with the product. I did have some issues. Frist, the screws that came in the kit for the mass flow sensor were different threads. One was course and one was fine. I had to buy new screws to get it to work. Second, the spacers were missing for that mass flow sensor. Again I had to go buy those. Overall great product and I noticed an instant increase of horsepower.

2003 S-Runner 108,000 miles with factory installed S/C and headers. The new intake is a nice performance addition. Factory air filter box broke and this was cheaper and a good performance boost.

I had problems with the bolts that hold together the mass flow sensor to the intake. The four bolts where not aligning with the threads on the the intake. I had to do mess with it and some how I made it work. It's not perfect but I'm hopping it works. The rest of the installation went well, if you have some basic understanding on car maintenance you can instal the K&N intake.
