Product Reviews      Review part E-1997

 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.
Joel Oliver, Wildwood, Minnesota
 Expected to get higher MAF readings on my tuner/data logger than the stock filter, readings the same.
Mark Snyder, Lucerne, Indiana
 The part was a great fit and was easy replacement for the stock part without any modifications.
Lynn W Dornan, Michigan
 
Product (E-1997) was shipped quickly, and arrived undamaged.

Installation was easy.....direct replacement for OEM filter...fit exactly as the original.

OEM filter needs replaced every 10k-11k miles @ $80 per filter.  K&N is a good value even if it does not last 50k miles.  Clearly less restrictive.

Thanks Mike

PS:  I have your filters in my other cars.
