so are you saying would be better to do hondata mod?I've recently taken the Gruppe M off my DC5 and reverted back to an OEM box with the Hondata mod.
There is an obvious change in noise as the Gruppe M is a lot louder and growls in VTEC. There isn't however any noticeable difference in performance. I'm not saying you won't get more power out of an aftermarket induction kit because you probably will, but the difference is negligible unless you remap the car etc.
the induction kit i have is enclosed and has cold air feed pipe on it. pulls much better than standard box, but i did try the standard airbox (no mod) and i must admit it is smoother each gear change.
cheers mate, its my first honda, just trying to find my way around the tuning of these. thanks for all your advice guys.
