So the masses have pretty much convinced me to swap out my Injen CAI for the stillen intake kit due to many different reasons. My question is, my 05 6mt Coupe has pretty much every bolt on and was tuned (uprev) a few years ago with all the bolt-ons (including the INJEN CAI). Would changing my intake and not getting re-tuned hurt the car at all - thinking AF ratio? I plan on getting re-tuned a year or so down the road, but after I redo my whole exhaust as well So basically, if changing my intake to the stillen may cause any issues, I can hold out on installing it until I am ready to get another oprev tune. thanks for any help!

 

Not necessary to re-tune. The flow of the filters isn't different enough to be an issue.

 

Thanks!
