You said how old you were, so I answered, means nothing. I didn't say the engine wasn't less restricted, I said they don't MAKE HP. The point is the amount of difference cannot be felt. You can say it can forever, but the dyno doesn't support it and never has. Yes they allow slightly better airflow (its less than 2%). If these things worked the factories would put them on. They aren't worth the problems they can potentally cause. As I said if you like them and don't mind the risk (however small) knock yourself out.
