Guys

For a gt35 turbo Evo 9 what would you choose? Running ets frot mount intercooler and shortest upper intercooler pipe , we know both units are overpriced for just an intake but the performa ce wise we leed a unir to perform as at least what an open cone filtre, so by the looks gruppeM takes some more credit with all the carbon ducting but their cone filter seems a bit small for a 600whp Evo....in the other hand, has the arc box proven to be no restriction for high boosted evos?

I have seen many dyplots and comparisons here but all uses open cone filtres on high poderes 4g63s,

Ruanos for the advance
