Just wanted to see what general opinion's are on Airaid & Roto-fab CAI's are. Thought I one time I heard they were one of the best. Any pros or con's to the kit? Am also wondering the same about the Roto-fab. I know the JRE dyno # test is out there but I want to hear some real world opinions on these two intake kits from those who have them on their 5th gen.
