I have been looking at cai lately, can someone give me an opinion on these. From what I can tell an intake is an intake, its just a 3 inch diameter pipe with a filter on the end of it correct?

yessir ur right about the intake diameter and all that, chrome intakes is known by alot of people that own grand ams and aleros, personally id go with doctorspeed but if your lookin to cut bak on prices i would say go with chrome intakes

got mine from chromeintakes. Love it :)

well I paid about $300 for the SE's CAI ,
and its the exact same as the Chromeintakes for $90.

The silicone boots on the expensive ones is a little thicker(maybe 1-2mm)but doesnt really make a differance.

Thanks, I went with the chromeintake cai.
