So today i was looking at my air filter and i did notice that i have a paper/foam filter. (stock 06 4.0l) and i was searching all day long in my mopar dealer ship autozone and much more and i couldn't find the same filter i bought a fram filter that has paper/ and some sort of cotton or something like that. air filter part number was CA8205
also i was wandering a few things
1.- I KNOW CAI DO WORK but they sacrifice protection to the engine by that i mean mud/water/ dust. but there is any filter that will fit on the stock airbox to gain more protection or mpg or hp.
i did saw this product in youtube what you think about it can it be true?
has anybody run this air filter?
2.- does the trumpet restrict air flow?
i think its small but will it restrict air flow? any mod to make the tube bigger or wider?
3.- can i remove the old foam and stick it to the new air filter just to make more protection? (of course clean it) or it will restrict air flow?
