You make good points, I must say that I agree with you for the most part. Like I said earlier, all show no go. So are you saying that when K&N advertises one of their intake kits (not the filter, the whole shabang) and say +10-15HP!! or whatever it is, they are full of it? Most of the time kits like that come with a box or partitions to block the hot engine air. Does your claim only hold true for rice burners or all cars? I agree with most of what you said regarding suspension and all that, but I have trouble believing that intakes and exhausts, decrease HP on the vast majority of cars. Yes, it does take a lot more than that to make a rice car truly fast, but it surely couldn't hurt one. Engineers have to design cars to meet certain noise standards, which would include intake noise and exhaust noise. It only makes sense to me, if an engine "breathes" better that HP will go up. I respect your opinion, but it goes against everything I have ever heard or read as an avid car nut.
