So why is everyone so anti-CAI?

Well, at least for the M42, the stock airbox is plenty big enough and offers very good filtration. The only real bottleneck is the intake tube behind the headlights. Replace that hose with a 3" diameter pipe and that is as good as you will get without a tuned resonance intake. Ghetto, yes, but it really is the best option. I'm not sure how different the M20 is in that respect, but you won't see much of a gain from a CAI.

They sound nice - that's something!!!

Are you guys saying that because you've run them and you've either lost power or done nothing.... or because that's what you've heard?

maybe because they do nothing on an e30?

CAI can be a good thing.... When done right...

But the bang for the buck is well...

Not much bang.

I've been debating on getting a CAI setup for my car but all I read is to not even bother. Are these people speaking from experience or just because they BELIEVE that they don't work?

The opinions seem to be really mixed. I'm asking because I'm debating between a Kamotors setup or the Signature Motoring shield on Ebay.

Facts & opinions wanted!:hitler:
