The K&N 57-2565 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Mustang GT models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Mustang GT’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 57-2565 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 breather hose. The oversized conical 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. The tools needed are a screw driver, ratchet set, pliers 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.

 I WAS VERY PLEASED WITH MY K&N AIR INTAKE KIT. IT BOOSTED THE POWER IN MY MUSTANG, AND IT SOUNDS BETTER. IT HAS LOTS OF PICK UP AND GO. THANK YOU FOR HAVING SUCH QUALITY PARTS FOR YOUR CUSTOMERS.

 Nice install. There is minimal additional intake noise and the additional noise is pleasant. The bracket that holds the intake tube that attaches with the valve cover bolts is bearing a bit on a radiator hose I'm keeping an eye on that to see if it causes any wear. I estimated it would take me an hour to install, but actually took almost 3, but that was with a lot of diddling and dropped tools skilled mechanic could easily do in an hour. I'm sure the power gains are there, but a couple percent on the street are really not distinguishable. The kit simply belongs on the Mustang GT. I should have done this long ago.

 Easy installation, can feel the power increase and sound is so good I may pass on cat-back! This is at least the fifth K&N Cold Air intake I have installed over the years and the quality of your product is always a pleasant surprise. I would never consider any other brand.
