K&N 33-5013 Air Filter Product Reviews

Wednesday, October 19, 2016 - Part 33-5013
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.

K&N air filters are well worth the cost. Had to order mine (2015 Acura MDX) since no local auto parts places carried it but again, it is well worth it. Just make sure you affix the decal on the air filter housing to make sure someone does not replace it if you get it serviced other than yourself.

I always replace the OEM filter in a new car with a K&N Air Filter and have never been disappointed.
