 Great product. I only use K&N filters on my 2008 Bullitt!
Patrick Chellino, Las Vegas Nevada
 This air filter is a significant improvement over the original equipment. Engine is noticably more responsive. If you are lucky enough to have a Bullitt Mustang, there are only two modifications that I recommend. One is to upgrade tires to 255/45/18 [brand], and the other is to upgrade cold air intake with K&N high flow filter!

 Great product and reliability. A brand performance enthusiasts have learned to trust.
