I know, what are you gonna do?

You lead them to water and they still run along the shore.

 

FWIW most all "COLD AIR INTAKES" which scavenge air from the engine bay are BS. The MKIV VW community has this great program called VAG-COM, it allowed us to see the measureing blocks from the bosche engine managment. It showed through the IAT sensor that most of these COLD AIR INTAKES actually were bringing in significantly more HOT air. The only difference was the ruduction in restriction which could be measured by the change in the MAP sensor. Unless you have a fresh air feed (read snorkle, or ram air) you're actually not helping a whole lot. Couple that with the fact that unless you rev the engine fairly high, you'll never see most of the gains. Dyno's on multiple vehicles TYPICALLY show the gains to be in the upper RPMs where flow was an issue. On turbo cars freeing up the exhaust helped some because you could spool the car faster, which could get you some torque, but up to the point where the turbo spooled cars typically LOST torque. This is typically due to the loss in backpressure. I'd be willing to bet most gains reported by any CIA manufacture are over 3500rpms in most cases. It's not that I'm against CIA's but they don't make sence on a NA car that you want torque down low.
