K&N 33-2111 Air Filter Product Reviews

Tuesday, November 21, 2017 - Part 33-2111
I purchased a 2001 corvette with 29700 miles on it. As part of the complete service I performed,I replaced the air filter with a K&N filter. The air filter was the original one and looked pretty clean. When I road tested it there was a noticeable difference in performance. I am developing the corvette into a show car. I have 3 other classic show cars. On 2 of them I us K&N air filters. The 3rd one is an oil bath filter.

Usual great quality, Was a difficult fit in my Corvette with the extra gasket. Glue on the gasket isn't sticky enough.

Give you 5 stars regardless. Have had your filters in all my vehicles. This one is going into a collector car but I haven't installed it yet. It looks like there already is an aftermarket filter in there, but I don't know what it is. It's not yours, I can tell you that. When I have time I will put it in. Love your products, keep them coming!
