i thought this was a brand name debate... i voted K&N just because they have been around forever. when i look at buying parts i look for the stuff that works. what defines "works" better than the fact that its been in use by everyone for a long time. air raid and aem are new companys. granted they use the same idea as K&N with the oil impregnated cloth filters. its just that K&N have been there done that and have a great track record
I am going to have to go with Rusty's just because of the price and the lack of confusion of what to get. K&N all look different, so you don't know wht type of hoses you're getting, or the shield placement.
