      Improves Horsepower. The K&N "Fuel Injection Performance Kit" (FIPK for short) Air Intake kit completely replaces your stock 1996-2004 GT Mustangs restrictive factory air box and paper filter with a high flow K&N filter assembly and intake tube for a noticeable increase in horsepower and acceleration while still providing excellent filtration.

      Filters out harmful contaminants. The supplied K&N Filter successfully 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.

      Straight Forward Installation. The 1996-2004 Mustang GT K&N FIPK Air Intake kit installs with commonly available basic hand tools, with no extra modifications required for installation.

        Feel the difference

        This cold air intake was easy to install my friend thought he knew but i just followed the instructions and did it myself. This was the first mod for my 2002 mustang gt and i got to feel exactly how much faster it felt. Will recommend

        I noticed immediate power gains and a nice, deep exhaust growl with this CAI. Works well with my Flowmaster. Instructions not very helpful. Put together with trial and error and common sense.

        The 57 FIPK was a great fit for my 2001 stage 3 Roush. I can feel and hear a difference in air flow from the m90 supercharger.

        K N air intake

        Great cold air intake fits perfectly and increases horsepower. Makes engine breath a lot better. Felt a big difference in a 4th gear pull.

        5 1999 GT - HunterP Installation Time: Afternoon

        great product

        This is definitely a great cold air intake for my 99 GT however I ran into one problem. The intake uses two brackets that that will then meet and tighten down on a bolt that comes out right below the valve cover if I remember correctly. On my gt that bolt wasn't there, instead, wires were exiting through that hole. So instead I had to zip tie the intake to the side panel and now it stays in place fine. If you have a 99 GT make sure your aware that you don't have that bolt coming out of your motor, its wires.

        Excellent CAI

        Gains power and gives it a meaner sound. Im sure it would gain from an aftermarket exhaust

      5 Top Rated Questions

      I want to add the most power I can possible should I go with this product or a bbk cold air intake?

      • On a 96-04 Mustang, the BBK Cold Air intake will get you a bit more power than the K&N FIPK Cold Air Intake.

      Will I have any issues fitting this to my 2000 Saleen with the supercharger?

      • The 2000 Saleen Supercharged Mustangs have slightly different intake fitment, so this will not work on that Mustang.

      Will this work with BBK 78mm T/B? Does the upper hose coupler from the plastic intake tube directly fit onto the intake port of the 78mm T/B or will I need to find a new hose?

      • BBK includes multiple fittings in the 78 T/B kit since the hose sizes changed halfway through the 99-04 production. So, the shouldn't be a need to change the hose itself. However, the coupler connecting the FIPK to the mouth of the T/B should be changed.

      Where do i find the optional tune

      So there's a little gap where the gasket and long/short bracket go. Should I be concerned?

      • I would suggest contacting our customer service department, as we would want to see some photos of the gap to be sure that you are not missing anything!
