AEM and INJEN CAI are good Intakes i would prefer AEM from those two but the best is TPR, no boggin that happens on the lower RPMs. boggin is very noticable its like your car is choking or about to stall. its not worth installing if you are the unlucky to get the boggin but there are people who have either Intake and dont get this boggin, but go TPR they are cheaper, perform better, and will not give you any boggin
