Personally I like the AEM because it doesn't narrow done at the end and doesn't have that long arss tube sticking it out of it for the BPV (I have the GT28RS so my inlet is a full 3" instead of the 2" on the factory MSP turbo.)
Looks like the CARB information on the AEM is on the filter side of the MAF instead of the turbo side, which sucks because you can't turn it into a short ram and still have the carp sticker in the engine bay.. doh!
ya no problem. I think i am going to keep the injen to be honest with you. I think it fits a little better. I think that they spend a little more time designing it. unlike the aem you dont need to use a piece of hose to connect the bov. I kinda like the black though better than the chrome. As far as sound / spool time they are about the same. THe stickers are exactly like you said.
