Big difference in performance and pays for itself in only a few oil changes! Completely worth it in every way.

Excellent fit and finish. Well constructed metal webbing. Very nice quality. Oil well but not too well. Improved throttle response on the HEMI. Only a few dollars more than a quality paper filter. Why you're there, clean out the air flow sensor in the intake tube. It probably needs it. Enjoy !
Spectre Air Filter Reviews
Seems as good
Reviewed By Tim A (New Fairfield, CT) Reviewed for a 2017 Subaru Legacy —3/28/2018 8:56 AM
Have owned K & N and this seems identical, was given this survey only 2,000 miles in so longevity is in question but I can't imagine any issues. Fit was great and seems as good as K & N but doesn't cost as much.

"I have 4 K&N filters that I have installed in various vehicles. BMW Motorcycle, 73 Ford Pinto, 85 Ford EXP and 00 Mustang. Each vehicle I noticed improved performance most notably was the Pinto. I had installed a hipo cam, header with larger exhaust and a dual port intake. The car really responded when I installed the new filter and housing." —George E from Cheyenne, WY bought a K&N Air Filters for a 1981 Ford F-100, 4.9L 6-cyl. engine.
