Which cold air intake?
 

Im torn between Z1, Takeda, and AAM. Im leaning mlre towards the takeda for the carb legal aspect. What do you think?

Go with the one that looks the best to you because that's all your paying for.

The Stillen G3 is CARB legal.

I'd actually go biggest. I know they all neck down or use OEM ID pipe but go biggest! I think that's takeda at like 2.75"OD. I do like Z1's filter design on the inside though.

I was trying to keep the price below $450. I actually got the AAM Comp intake for $420 on Ebay just a few moments ago. I know they use 2.75 inch piping instead of the 2.5. All i need now is a remap!

Take a look at the Z1 CAI.

HAD STILLEN, NOW Z1, I was satisfied with both. Z1 is cheaper.

Cool thing about the Z1 is that you do not have to cut anything to instal them. The Z1 CAI is not necessarily cheaper, it's just more affordable than some of the others.

Yes but you only get the max gains they claim if you do cut the radiator support, so now your back to the same as Stillen G3. I went G3, enough people have them with no issues and your only trimming a very minor portion of the support that wouldn't even be noticeable if you went back to Oem.

This.
This was my issue when I was looking for an intake. Removing the bumper is fast and easy. The cutting/trimming was very easy as well. I used a small dremel tool to cut and you only remove so much of the support. I like how the intake sits as well- behind the bumper. Gives the inside a more cleaner look imo. You can also hear the air being sucked in, into the intake.. Sort of like air going through a metal piping. Just had to zip tie some areas near the filters so there would be no shaking and rattling.
+1 on the G3. Smog legal as well if it suits you.

I prefer the Nismo R-Tune intakes over the ones listed. They look fantastic and seeing the word Nismo in my engine bay makes me that much more happy. No cutting required either just a bit of drilling to relocate the windshield washer reservoir.

Z1 hands down. I like the stealth look in black:
