K&N 33-2141-1 Air Filter Product Reviews

Monday, August 22, 2016 - Part 33-2141-1
The most noticeable difference is a much improved pep when I step on the throttle. I have not noticed any improvement in mileage yet, but the added acceleration really feels like I added several horsepower. I have always had great results with all the products I have used. Fit like a glove and performs great.

Thank you so much! I didn't realize I had to change the filter every 30,000 miles. My 2003 Jeff Gordon car just hit 36,000.....the change actually makes the care run a little better....though it normally does run fantastic. Thank you

Product arrived within a few days. Looks easy to install and came with intelligent directions. I won't know if it is of any value until I drive long enough to see if there is any change in my 18mpg in town driving records of the past two years.
