need opinions please....

I have 2 options on getting CAI...

I can get a used CF dinan CAI for $300 or GruppeM CAI brand new for $650(not suree on price)

Does the GruppeM have that much more HP gains than Dinan??
anyone have the actual dyno on these 2??

i think someone posted the two dynos in the past... gruppeM has been quite popular as of late. I would go with gruppeM for the cf look and dinan discontinued theres... i would want new.... thats just me

The "avg" (not best, not worst, but middle) dyno run of both showed the GruppeM is clearly better. The difference was 5.3 hp, 2.4 ft-lbs at the rear wheels. Also, there may be a gb for the GruppeM right now, in which case the cost is more like $500. Check www.rennsport.net

A used cold air intake should not affect performance too much as long as there are no cracks in the cf and the filter is good and close to new. This item probably wears very well compared to other performance mods such as a used exhaust or clutch or headers and cams.

Check out the dyno's in my sig. I've seen the power increase from one to the other and I definitly felt a difference. I did it impartially and decided to keep whichever CAI worked out better. The Gruppe M definitly turned out better and overall had a better more aggressive sound to it after 3.5k rpm. under 3.5k it sounds very civilized

Thanks, Samir. Nice, but not the dramatic differences like Dinan to Gruppe M 325. Why do you think there's a difference? How does it compare to Dinan on 330?
