Okay, so I was recently told that my AEM Cold Air Intake does absolutely nothing to benifit my car. That a stock air cleaner is actually better then the AEM. I am not sure I believe this. How and why would all the intake manufacturers post "factual" results?

So many variables to take into account - but isn't a cold air intake better if properly shielded (to make sure you're taking in COLD and not HOT air?

The orgonal question is intriguing - if ALL these manufacturers are claiming that their intakes and filters improve performance - are they ALL wrong and we ALL right?

So many people just dismiss these intake kits without explaining. Like you. The filter companies all provide these great "results". Their arguement is a little more compelling. They explain themselves. I think this is where the confusion from the original poster (and myself) comes in.

I've search this forum over and over and can't find a definitive answer. Anyone care to try and give a detailed and reasoned answer - one way or the other?

and guess what, it's hot. I think the factory airbox is great, does a great job with quieting the turbo sound. An intake in most cases isn't going to gain or lose you much. I can say this, my APR airbox with my current turbo setup did gain me some g/s in MAF readings. Is it the filters? The airbox design? I have no idea, but my logs don't lie. I'm not so sure there is much to gain on the smaller turbos with MAF housings and software that are getting maxed out anyways.

I have a non-turbo 1.8. It's a Euro thing I guess.

Will a CAI help more, less or the same on a non-turbo engine? (Again - assuming proper shilding, etc).

in some cars, the stock airbox and filter flow better than others. Actually, I can't say I did my comparison to a stock setup. I was actually comparing my home made cone setup to my APR airbox. I haven't had a stock box in quite some time now.

So it is better for performance than a HAI.

Never, *NEVER* belive a manufacturers claims or even worse is claims from magazines.

Magazines regularly skew results so the biggest advertiser gets the best results.

As for the aftermarket filter/K&amp;N people, you should read this and then decide how badly you want that extra 1hp.<ul><li><a href="http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm">K&amp;N Dirt Inhaler (Tm)</a></li></ul>

I've read it before. Genal idea seems to be that K&amp;N filters allow more in in - but also more dirt. Correct?

I'd never put a K&amp;N on my car again, when I did it killed my MAF before...
