    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.

        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.

        • It definitely will have it on an 06 with the ford racing intake

        I bought the Ford Performance cold air intake with the 85 mm mass air meter housing, will this filter fit my kit for the V6 05-09?

        • This K&N Replacement Air Filter is a direct fit replacement for the stock air box. Many enthusiast have used this filter for the Ford Performance Cold Air Intake, item 50141, however, we have not tested this for fitment. https://www.americanmuscle.com/fordracing-cai-0509v6.html

        Has anyone had trouble with the rubber under the hose clamp "coming apart" in areas with hot temperatures, such as Texas or Arizona? I was popped the hood on mine to check everything out and the filter basically came off in my hand w/o me touch the hose clamp.

        • Unfortunately, this is not a common issue with these filters and could have been due to the clamp being overtightened and cutting into the filter neck.

            Filter replacement

            Its a filter. Not much to be said here - it does it's job as well as it could. This filter is a little bit longer than an OEM Bullitt filter though so it will require some finagling to get into place.

            More power

            Always kandn is the best. My ford racing air filter needed to be replaced so I went for this option knowing that kandn are reusables . Installing it took just 10 min. Not 100 accurate to fit in the air box as the paper filter but i would say 99. Once it was all set the engine started breathing again, huge difference between kandn and paper filters. Highly recommend. Two tumps up.

            5 2008 GT - pfarabee

            Before you try to install, read this review.

            It takes 24 hours or so to properly clean and prepare this filter. I'm buying a second so I can change the filter and clean the dirty one and reapply the oil to it at my leisure. That way my GT isn't down for a full day or so while I muck with it. NOTE: You cannot just remove the hose clamp at the filter and then change it! You need to loosen the hose mounting as well, so you can pull the entire hose end up out of the housing, then remove the filter, then apply the new filter and reset the hose in the housing. It is only a couple more screws, no biggie. Don't bend your filter trying to force it in! Loosen the hose mounting and pull the end of the hose up to change it. As for the filter itself, it runs a bit more air than the Ford Racing blue paper, and gives a bit more throat to the exhaust as a result. Reusable, a smidge more power, and a bit of extra grumble.. what's not to like? Vroooom!

            Better than stock ford racing filter

            I have a v6 with the ford racing cold air intake and didn't want to pay $35 every time I needed a new air filter, and I've always used the KandN brand. The fit of the locating tabs is not exact, but with some finesse and patience, it will drop right in. Makes a nice noice when you get on it and when you let off the gas. Good option versus paper filter.

            K N Air Filter

            I found it a lot easier to take off the entire CAI system from the TB, it allowed me to instal the filter outside of the shield and install the entire system in one piece. It also made it so I wouldn't bend or damage the filter. This installation was so much easier and I recommend doing it this way to avoiding the struggle.

            PERFORMANCE BETTER THAN EXPECTED

            Replaced the Ford Racing Cold Air Kit filter with the KandN because it gives a cleaner under the hood appearance. Installation took 10 minutes by loosening the two bolts holding the bucket assembly and installing the filter with clamp. Surprisingly, I feel a slight improvement in performance with the KandN over the Ford performance filter.
