i need a new air filter and i have a bully dog intake and the filter is shot. i went to my local shop where they sell new flters and they wanted 70 bucks for the filter and another 28 for the sock that goes over the filter... the guy is also looking into a boost fooler as well but im probably going too buy one from here.... i was just wondering if i needed too buy a bully dog filter or if there was a cheaper filter that would work thanks
