      Reclaim Lost HP and Acceleration. Regain lost ponies and acceleration for your Mach 1 by replacing the filthy, clogged up filter element on your current FIPK Cold Air with a new K&N Intake Replacement Air Filter. This filter will protect your 4V engine against dust and dirt and the rubber flanges will absorb any unwanted vibrations, making this a superb choice for a 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 2003-2004 Mach 1 Mustangs with the K&N FIPK Cold Air Intake part# 57-2555 installed.
