The K&N 57-2537 FIPK air intake system replaces the restrictive factory air filter and air intake. 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 57-2537 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 crank case vent hose. 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 existing factory mounting points. The tools needed are a screwdriver, a ratchet set, side cutters and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Delivered on date as stated. Awesome filter. Best filter, no question. Great buy. The part was very easy to install and fit perfectly. A good company to deal with that gets it right the first time. Very pleased, and arrived quickly.

This filter and intake really woke up my 2003 Mercury SUV. Sounds good and mpg went up even with 144,000 miles on this vehicle.

Really opened up the potential in my v6. I got another 2 mpg without having to change my driving style. Install as is with every K and N product I have used was a breeze. That and the really fast shipping left me really happy.

Installation was a breeze. Couldn't tell a performance difference until I did 2 over the road trips. Seeing somewhere around an 8 to 10% increase in fuel efficiency. I would recommend, purchase and install.
