gruppe m carbon intake vs dual cone intake

i have recently been looking at the various intake options for the 335 and i know there is a big difference in price but i havent seen any power gain results from the gruppe m intake so i was wondering if anyone could tell me which of the 2 is better

the gruppe m's fit and finish is better but imho that's all you're paying for - looks and the name. the DCI design has made proven gains. i doubt anyone knows if the gruppe m even makes legitimate gains because no one has one to dyno and confirm. if you're wiling to go the the gruppe m intake please come back and post your dyno results
