K&N 33-2045 Air Filter Product Reviews

Wednesday, November 11, 2015 - Part 33-2045
Great product but just had to return it brand new in box due to the fact that I found my original K&N Filter Charger and replaced the OEM setup with it and did not need the K&N OEM style filter replacement.

At first the filter didn't fit the stock air box on my 1996 mitsubishi 3000GT correctly, but after messing with it for 5 minutes it worked fine and I can feel the engine breathing better. I would definitely recommend it.
