Seriously this mod is awesome. I just got around to it today. I bought a universal K&N like filter and did the exact same setup as AGR and man is it sweet. I can finally here my turbo in every gear especially at 9psi lol! I cant wait till that intake comes out as well. THen a blow off valve THEN INTERCOOLER THEN EXHAUST HAHAHAHA Im gonna mod the heck out of this car it has so much potential. God I <3 my mazdaspeed. In other news I beat a 300ZX from 0-60 then he pulled on me after that and eventually about 1 car ahead when we hit 90. It was good stuff. I dont think he had many mods... becuase I thought those cars were out of our league?
