Great product and easy to install.  It took the cob webs out of the performance of my '98 Buick Regal GS.  Before K&N it was sluggish to the point that I was considering another car, but with your filter installed I got the old pep back.  Thanks.

I have been using K&N products for 25+ years and will not purchase any other product. It makes my Cadillac PURR.
