So, I see that the Intake is $195. This isn't bad and I'd save up a week or so and be able to buy it for myself, but my question is, do I need the COBB air box? or will it fit in the OEM airbox? HELP PLEASE!
It won't fit in the stock airbox, thus the reason Cobb made their own...Originally Posted by Mike193
If you want the intake to draw in the same air as the stock box, buy the airbox. If you're fine with it drawing in the hot ambient engine air (which your stock airbox does NOT do), then don't buy the Cobb box.

on hotter temps the airbox helps. no oem wont fit
IAT sensor is located in the MAF. There are timing compensations for IAT. A SRI can cause you to be pulling massive amounts of timing. Do you want a nice downgrade for your money? If not, buy the airbox or go with an AEM unit.

You definitely need the airbox otherwise, as others have said, you are wasting your money. Also, be advised that this intake is very LOUD. There are some YouTube videos out there that you can check out if you want to get an idea what it will sound like.
I personally love the sound but I know others have regretted putting it on after driving with it for a while. Just my .02.
While we're talking about this.... does anybody know how GOOD the Cobb box actually is? I'll search around too, but I was just wondering if it does reduce the IAT's. Is it as good or better at that than the stock one? I've heard (no support) that the area the SRI sits in doesn't get all that much hot engine air and it isn't so bad. I have one with a box, but haven't put it on yet because of this... and the need for calibrating.
I have not seen back-to-back IAT readings of airbox vs exposed filter.

I didnt plan on going with an exposed filter! I was just confused because I figured it would fit in the OEM airbox just because they sell them separate, it would make sense to sell them as one single unit if you need both.
thanks for the help tho guys
