K&N 33-5013 Air Filter Product Reviews

Thursday, February 22, 2018 - Part 33-5013
Very easy to install and immediately noticed the difference in improved acceleration + the few extra MPG :). All of my cars have a replacement K&N filter. Very happy with my purchase and worth every dollar spent.

The first item I buy when I purchase a new vehicle is a K&N Air Filter. I was also able to purchase the Filter Cleaning Kit to clean the Air Filter I have in my other vehicle that has 189,000 miles.

Perfect replacement of OEM engine air filter. Too soon to determine if performance will be improved but past experience tells me it will improve. Shipping box really took a beating but contents were undamaged. The decal advising not to discard the air filter was dried out and the back would not separate to expose the adhesive. If possible I would appreciate it if you would send another decal.
