most of the people that installed CAI seem to go with INJEN

Is it that much better than Stillen??
I was thinking about going with STILLEN due to its stock look and easy install??

I can't tell you why, but I just finished installing the stillen. It was pretty easy. Took me around 30 minutes.

I thought it would be loud, but I think our stock exuast noise is louder than the intake. My BMW had a better purr from the intake.

Can I notice a difference in power. Not sure, cause I still in the breakin period of car, so I guess I would never know since I never took the G to it's limit.

Won't really notice the sound untill about 5 grand in the RPM range.
