Reclaim lost horsepower and acceleration from your GT500 by replacing the filthy, clogged up filter element on your current Cold Air with a new K&N Intake Replacement Air Filter. This filter will protect your Shelby from getting dust and dirt in your engine 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 2010-2014 GT500 Mustangs with the K&N Series 63 AirCharger High Performance Intake part# 63-2579 installed.

        GT 500 Air Filter

        The product doesn’t fit to my 2011 mustang gt 500 . This air filter( KandN RF-1044) it’s flange inside diameter is bigger than the required diameter. Not recommended to replace the 2011 GT500 air filter.

        Great small upgrade!

        Fast easy install, the filter comes with a new adjustable band in box, as well as a KandN sticker. The filter itself comes already lubed with the filter oil so no need to get a recharge kit or anything. After installing, I noticed slightly better throttle response and you can hear the supercharger whine at a little lower rpm's. Overall, great little upgrade if you're on a budget.

        K N Intake

        K N intake never fails. Have used K N for years on other vehicles owned. It is a no brainer to add one of these to your automobile for improved breathing, better air flow, improved engine performance. Go Get ONE!

        Good replacement of the stock unit

        My stock filter was really clogged up, so went with a KandN replacement. Fit perfectly and really cleans up the engine bay. Can't say there was any performance gain, but I rest easier at night knowing that my Shelby isn't breathing through a clogged filter.
