I just got done takeing off the stock air filter box and air filter, I also removed the the mass air flow chamber and module, I connected a K&N connical filter directly to the black rubber tube or chamber that is directly connected to the throttle body. I took her for a spin and did find a noticable gain in pull almost the hole way through. Does anyone know of any bad side effects that would result from the removal of the MAF unit? The MAF looked very restrictive anyway. Tell me what you think?
