      Improves Horsepower. Now you can improve your 2007-2009 Shelby GT500 Mustangs performance with a K&N Drop-in Replacement Air Filter. Simply replace your stock restrictive paper air filter with a new high flow K&N air filter and feel an increase in horsepower and acceleration while still providing excellent filtration.

      Filters out harmful contaminants. The K&N Drop-in Air Filter filter's out harmful contaminants with it's unique layered design. 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. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton's microscopic strands creating a powerful filtering media that ensures engine protection.

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

      Drop-In Replacement. K&N designed this Air filter to be a direct drop-in replacement for the stock 2007-2009 Shelby GT500 Mustangs air box, with no cutting or trimming required.

        Good product

        It does mostly as advertised. It fits right in the box with no problems. The filter is simple to clean. Power gains? I haven't noticed any, but I never expected any to begin with. Overall it is a good product that I recommend if you hate paper filters and want to save up for a MAF CAI.
