But my butt dyno says the car revs smoother on the topend, doesn't sound very different, but looks great under the engine bay. I was also thinking about just making a 90° tube and have it come directly out the foglight area so it will take direct air up the tube. For the price i think it is worth it, and the design of having the air tube allows for modifications to make it better which i like. It seems this set-up has produce horsepower gains on the E36 M3, Mini, S4, S2000, etc etc....although no dyno results have been posted for the E46 M3 yet.

List price is $999, street price $850, or email me for more info. Just keep in mind it is out of stock for a few weeks...as it comes straight from Italy.

What do you have to do with the mass air sensor? Do you reinstall it and the screen in that metal housing?
