    Reclaim Lost HP and Acceleration. Reclaim the lost power and acceleration from your 3.8L or 3.9L V6 by replacing the filthy, clogged up filter element on your current K&N Cold Air with a new K&N Intake Replacement Air Filter. This filter will protect your Mustang's engine against dust and dirt and the rubber flanges will absorb any unwanted vibrations, making this one great replacement air filter.

    Superior Filtration. This K&N Replacement Air Filter provides superior air filtration and successfully filters out harmful contaminants with its high-flow cotton gauze material. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. The filter has been pre-treated with specially formulated grade K&N oil and is ready to be installed right out of the box.

    Washable, Reusable Filter. K&N design their high flow air filters to be reusable. That means there is no need to buy a new filter every few thousand miles. You can just wash the filter, re-oil it and save money with a K&N Filter Recharge Kit.

    Application. This K&N Replacement Air Filter is designed to be a direct fit replacement for the 1999-2004 3.8L or 3.9L V6 Mustangs with the K&N FIPK Cold Air Intake part# 57-2532 installed.

      Luv the filter. Not sure way the first one all of a sudden didn't fit anymore. Glad I was able to replaced the filter instead replacing the whole cold air intake unit. Thanks American Muscle

      Great Filter and Fast Shipping

      The KandN that was on the car when I purchased it was filthy and dark black. So ordered a new one here instead of bothering to clean it and very satisfied. It's like the difference between night and day.

      Great replacement

      Took my car up onto some dusty back roads for a family vacation. Long story short the filter was caked in dust and I decided to replace it since I have had it for a while. Love the replacement.
