The concept of getting a money worth it gain without risk of damaging components is not realistic. No pain, no gain. You may get a few out of intake and exhaust, but as Billy said, the intake is pretty good. if you look at where the suction is, its actually in the wheel well outside the engine compartment. Short of a ram air, I cannot see the difference. I have the Injen intake, I don't know if its faster or not, but it sounds a lot cooler
