I too hate seeing people put others down for buying aftermarket engine upgrades.

Aftermarket upgrades do work, and do add power, fuel economy, etc. They just have to be used in the right application.

i.e. - My Honda Prelude absolutely loves more air. When I installed the CAI on it I could feel the difference than without it.

Again, the point is you have to add these things to the right vehicle. My prelude redlines at 7000 rpm's, and the limiter is at 8000 RPM's. When I finally get a turbo on it, it will be pushing 10,000 RPM's. So upgrades that hurt bottom end torque is not a problem imy application.

Anything you can do to any motor to make it breathe better, whether it be exhaust, intake, or whatever, will always have some benefit over the stock setup. Unless of course you put a full 3 inch exhaust or something on a N/A car. N/A's do need back pressure, boosted vehicles do not.

Anyway, me recommendation would be to not get a TB spacer, I would get a bigger TB. My 2ó.
