GruppeM is world renown for their carbon fiber intakes, it could be the combination for proven power, exclusiveness, and extremely high price. GruppeM has released their Ram Air System for Volkswagen’s newest revision of the GTI, as expected the kit includes a carbon fiber shroud to effectively funnel colder air into the include cone filter.  Vendor provided dyno charts show a gain of about 5hp or so.
