every car is different, you cant justify his statement just because they used a skyline as a test mule. depending on the setup of the intake you will see some gains under the hood. Airflow needs to be smooth going thru the MAF for optimal reading and gains. if the air filter is bolted on directly to the MAF then the turbulence wont have time to smooth-en out before it reaches the MAF sensor. attaching an intake elbow on the MAF with a filter at the end will show more gain because the air flow is smooth by the time it gets to the MAF. its all about air flow.

The true CAI made 6whp over stock...and they were using crappy tubing. True CAI's do make power.

I think this is a valid question.

Would the results differ using a N/A car? My thought process is they have a turbo compressing and heating up the air. Would a N/A set up experience the same result or slightly better or slightly worse?

Would the same results be seen on a N/A application?

This must mean that the intake on a CSL M3 would have no beneficial effect... Yeah right. .

The stock airbox on the 330i's pretty well thought out due to the ram air induction that introduces cold air from the gills. And then there's hot air from the engine bay you could have from the majority of air intakes in the market- and that's a no-no. So the only intake I could see benefiting from would be the Gruppe M, and I'm not paying 1-2k for it.

It would be silly to put a cheap Cosmo air intake and not have the benefit of being able to use the gills.

omg this is such a pointless thread, put it this way. if you want to hook up your car then why not throw in a aftermarket intake seriously. who mods their car without installing an aftermarket intake shit might as well. plus it sounds cool

Anywho, does anyone know of an intake similar to the Gruppe M intake that's not in that price range? Or any intake that'll allow the ram air induction towards the gills' ? I've been searching with no results.

...ram air
DINAN long tube clone makes the most power.

I'm looking for anyone who knows anything about cars, not those who "pretend" or are posers and have time to be keyboard warriors.

Basically, I'm looking for an intake similar to the Gruppe M. Why? Because it uses the same factory concept of introducing cold air through the front gills. Yea I know the Dinan long tube is a good intake, but I'm not looking for that. There's a reason these engineers spent so much time perfecting this. And I hear you lose torque, I don't want to lose that.
