Good Product

Reviewed By Anthony D (SAN LEANDRO, CA) Reviewed for a 2013 Audi S4 —6/3/2014 8:52 AM

Just installed this air filter and it looks great. Slight increase in power. Still waiting to crunch the numbers on fuel economy. I definitely prefer this filter to one you have to re-oil. Overall I'm happy with my purchase.

Nice looking filter real tight fit took a little patience, seems like the truck is breathing better but have not noticed any fuel mileage improvement
