K&N Replacement Air Filter

Just bought this 81 Merc Capri GS 3.3L registered for California. It has just over 149,000 miles on the original powertrain, and with the addition of the K&N and proper maintenance, will get significantly more. I have this confidence because my 92 Ford Mustang LX 5.0 with the original powertrain, and K&N with proper maintenance since 1992 now has over 372, 000 miles on it. Thanks K&N for an awesome, durable product (:

I'm in the horse industry and got tired of dust clogging up my filters every month from going to events. Not only do I not have to buy a new filter monthly, but I get a noticeable boost during highway driving. I can accelerate up hills using overdrive in an 80's Ford 4.9L, not an easy feat considering everything else is stock. It's also helped a touch with the mpg's. I went from 18-20 to 20-22.

Had one on this vehicle before and love these filters. Haven't found correct replacements for K&N on lawnmower and weed eater but I'm sure it would be an immediate upgrade and worth the money.

I have purchased K&N filters for every vehicle I have ever owned & really been satisfied with the performance. I purchased this filter for my little Toyota truck and this is the 1 st time it has shown me very little. Still a believer in the product as it has been good to me in the past . Great product 👍🏼
