K&N 33-2111 Air Filter Product Reviews

Monday, July 9, 2018 - Part 33-2111
Got this for my 1999 454 7.4 motorhome. Also took out exhaust manifold and installed headers and Banks power exhaust. This made a NOTICEABLE difference. Just adding this filter I swear u can feel it sucking in air a lot better. So happy didn’t expect such a difference just from this filter but it def added horses. Good for the engine
