The K&N 57-2555 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Mustang Mach 1 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 57-2555 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 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.

Customer Feedback

I used this filter as a special Air Cleaner replacement for a 1955 Ford Thunderbird that otherwise would normally have an Oil Bath air cleaner. There is a company that makes air filter cleaner replacements for the old Oil Bath cleaners and I upgraded the included air filter to a K&N Filter, and I am happy with the results. For anyone else that has a 1955 or 1956 Ford Thunderbird with the original Oil Bath cleaner, you can upgrade to an air filter cleaner assembly from (Brand Name) and then upgrade the air filter to a K&N. Hope this helps any fellow '55-'56 T-Bird owners.

Installed the K&N 63-2587 on my 2014 Ford Fiesta ST. Installation only took about a half hour & was simple following the step by step instructions. The K&N cold air intake provides better throttle response along with a cool sound. For those who are worried about heat soak, its only s couple degrees higher than the restrictive factory air box. The only way you would get heat soak is if you were stuck in traffic in 100 degree weather. I live in New Jersey where it can get 90 plus degrees with high humidity & I have never had an issue. I have no regrets putting this on my car. It was money well spent. You can feel the difference as soon as you drive it.

I had bought an air filter for my 2007 V-6 Suzuki Grand Vitara. I just returned from a trip to Nevada. The trip is 2600 miles. We do this every Spring . We keep good records of the gas and mileage. With the new K&N air filter we got 4 miles to the gallon more. Also I had a lot more power. Good product. I have a 2010 Ford F-250 with a Diesel motor. Do you make a filter for this motor? One that will not have to have any modifications.
