Filter is great, just as advertised.
Mauricio Garcia, El Paso, Texas
Great product and very easy to install. I noticed a big difference in the performance, my vehicle seems to have more power than with the original stock air filter.
Jeff Guilliams, Roanoke, Virginia
While the ordering experience was quick and easy. I have yet to notice any improvement in my mileage. Still think it's a worth while product.
