      Improves Horsepower. Now you can improve your 86-93 5.0 V8 pony's 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.

      Drop-In Replacement. K&N designed this Air filter to be a direct drop-in replacement for the stock 1986-1993 V8 5.0 Mustangs air box, no cutting or trimming required.

        Not a 5.0 air filter.

        Wrong size completely. Got it within a couple days Wich Wich was impressive, went to put it in and its 7/8 the size as stock. Wouldn't recommend the drop in I'd order the cylindrical filter..

        K N Drop-In Replacement Air Filter

        Really would recommend to someone who is looking to replace their old Air Filter. Easy to replace and really felt the difference after installing it. Throttle response increased in my Mustang.

        This upgrade is a must on all cars

        All my cars have a KandN filter, noticeable engine improvement. Yes more costly and then you need the cleaning kit, but if you love your care and want it performing well, then its worth it
