Description
Improves Horsepower. Now you can improve your 2008-2009 Bullitt Mustangs performance with a K&N Direct-Fit Replacement Air Filter. Simply replace your stock restrictive 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 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.

Direct Fit Replacement. K&N designed this Air filter to be a direct fit replacement for the 2008-2009 Bullitt Mustangs with the factory cold air intake.

Fit of filter My 2008 Bullitt Mustang has the original air filter. Will the K&N filter fit without any mdifications ?

JohnnyV Year: 2008 Model: Bullitt

  • Yes it fits perfectly however it is tight. With a little patience it will attach with no problems. Be sure to have the clamp on the filter before you install the filter.

Will this work with with a GT too? I have a Ford Racing CAI and this filter seems to be the same size and shape I use now. From what I understand, the Ford Racing replacement filter isn't cleanable/reusable and I would really like to get one of these if it I can.

    Great filter for my 2008 Bullitt

    If you're looking to replace that old, warped, ugly, dirty filter from the factory, then this is the filter to buy! This is cheap (price wise), and it is also a direct fit, reusable filter, and on the big plus side, it looks great under the hood. I have not noticed any performance gains at all, but the induction noise is just a tad bit throatier, hardly noticeable but it's there. The extra rubber bumps at the end of the filter is a little off from the factory heat shield cutout, but a little twisting of the filter kept that to a minimum, but it is still slightly off. I've always bought my filter from K&N, and they have not let me down!

    Bullitt Replacement Filter

    The filter would be great if it fit. It is too long for the filter box in my 2008 Mustang Bullitt. When I tried to fit it the filter kinked so because I damaged it I know you will not allow it to be returned for the correct filter. I thought a company that has so much focus on Mustangs would have a better research before making fit claims. Oh well, it was only $59 down the drain. Thanks

    • Response from AmericanMuscle

      This filter is designed by K&N specifically for your Bullitt application. Many others have installed this without any problems. I'd like to find out more regarding what didn't fit with your factory cold air and get a replacement shipped out to you!

    Great Filter

    I have a 2008 Bullitt. the Previous owner had put a small spectra filter on it. This filter made a big difference in response.. I have had K&N filters on other cars I have owned and was always satisfied with performance.

    Bullitt Filter

    If you own a 08-09 Bullitt this needs to be your first purchase. Ford wanted to charge me $ 100.00 bucks for an unwashable filter. so after you wash it twice, This K&N filter has already paid for itself, and it looks alot cleaner than the stock filter.

    HIGHLY RECOMMENDED!

    I recently purchased this product for my Mustang Bullitt 2009 & i have to say, the overall performance of my ride improved! I mean you can really feel the difference compared to the stock Round Air Filter. P.S. to those having a hard time with the fitting, just loosen the clamp before fitting the filter to the duct (make sure the bolts that holds the duct to the case is removed so that you fit the filter easily to the case). I actually had to problems at all with the fitting, like what the description says "Perfect Fit!"

    K n N upgrade for Ford Racing M-9603

    Was time to replace the element in my Ford Racing M-9603. Chose KnN because it is reusable and a fine looking unit. Install was effortless and very easy. I saw elsewhere that a customer had difficulty with the install and kinked the filter in the process. I removed the old filter and also removed the two hold down 10mm bolts that secure the air tube to the filter box. This provided lots of room for installing the element. After aligning the index tabs, tightening the band clamp and reinstalling the 10mm bolts the job was completed. Great Product Highly Recommended..

    Well worth the money

    This filter is well worth the money since I'll never have to buy another filter. It looks great along with all of my other dress-up additions under the hood (see photos). I show this car a lot. The Ford Racing OEM filters are dark gray and everyone always thought it was dirty and needing replacing even when it was brand new. Very easy to install in about 10 minutes. Fits just like the OEM filter. It's hard to say for sure but the performance seems better, more responsive. When you hit the throttle you can hear a rush of air being pulled in that I didn't hear before. Haven't had a chance to run out a tank of gas to see if I get better gas mileage. Was getting 24-26 MPG mixed use before. Should have bought this a long time ago.
