Timothy Watrous, Goodlettsville, Tennessee
I've used them for years on my Fieros. Good product.

The K&N filters I use are the HP-2001. I use them on a Chevy Tahoe 4x4. The filters are the best ones on the market The filters are also the easest to install because of the nut that is welded on the filter housing. Because of the tight area that the filter is located, the nut cuts a half hour job to just two minutes.

Excellent oil filter. Been using it for approximately 15 years now with no issues. I use it on my 1994 Chevrolet Silverado 1500 extended cab 2 wheel drive with over 254000 miles on it with the original motor that has never been rebuilt.
