I have been extremely happy with K&N air filters going back about fifteen years,when a friend recommended them. I just put the E-0940 in my Daughter's mustang, and right away you can feel the difference in power and smoothness. I have a K&N in all five of my vehicles. I'm still waiting for the one I ordered on line for my 1988 special edition Greenwood Corvette, which I hope is coming soon. I will definitely be a customer for life, since I have looked at similar products, but the quality is not as good. I also like that they're made here in the USA, (that's not easy to find these days.) Keep up the good work and never stop innovating. Sincerely, Brian Holmes
