See very good results on stillen g3 and better position on the filters but need to cut for install.

Injen cai is more work, but can go back to stock any time.

Which one?

 

yeah with injen you can go stock much eaiser than stillen but like you said the stillen offers better filter position ... i've had the stillen for almost a year and i love it.... the gains diffrence between the two is not much but if you much louder CAI go for Injen..

 

Before I did some test:
1. stillen gen1 intakes - very loud, no gain, lot of vibration inside.
2. stock with hks dry filters - good..
3. stock with k&n filters - i like it very much.

So I believe if i want some gains (10hp) maybe stillen is a good choice.
I saw some dyno graphs with good gains (I have BB kit, fast intentions hfc and exhaust, Bullydog) so maybe it will be good for me.

Let me know your impressions as today.

Thanks
