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.

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 have been using for 8 yrs. and am cleaning today, with 7,000 miles on it. I have 1986 Toyota Base Japannese aisian carb. rwd 4sp standard... pu,96,000 miles.. original owner. I can't notice any gas milage increase or power increase. I used to get 17 mpg around town, stop and go  about 3 miles a day (doesn't even warm up) in the suburbs, and 22 mpg  in the country and 26 mpg on the highway. This did not change with the K&N filter. The little truck with 22R is very fast to begin with (it's a little screamer),I have abused it since it was new, but nothing ever breaks...it's like a little Sherman Tank, so I can't notice any power increase. It does clean the intake air very good though, compared to other filters I have used. So it is good that way.

Greatest air filter made. You guys really know what you're doing. Thank you

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.
