Good question on the stock airbox flow rates of stock filter vs AEM/K&N. Would be in for info on that. If it flows plenty fine, that's good for me instead of eventually doing a CAI. I'd rather not if I don't need to. Do any intakes actually work on our car? And equally important, if there are, do you need a tune or anything? I saw a Cobb one, but I think it was for another car, but the lower portion seemed to match (where the cold-air funnel is). Any info on this?
