Review part E-1997
Tuesday, July 22, 2014 - Part E-1997
Great product. I only use K&N filters on my 2008 Bullitt!

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!

Expected to get higher MAF readings on my tuner/data logger than the stock filter, readings the same.

The part was a great fit and was easy replacement for the stock part without any modifications.

Product (E-1997) was shipped quickly, and arrived undamaged.

Installation was replacement for OEM 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.
