K&N 33-2411 Air Filter Product Reviews

Fast friendly and very knowledgeable. Part seems to help on low end horsepower.

I recently purchased a newer vehicle and one of the first things I did was to order a K&N air filter for it. I have used their filters for the past 17 years and a firm believer that they provide much better air flow than any others on the market. They provide a cooler running engine and never need to be replaced only cleaned and oiled when needed. Highly recommended.

Made an immediate, noticable difference in the acceleration and power of our vehicle. I have put K&N Air Filters in my last three vehicles and in each case they have been great
