GruppeM is notoriously known for being expensive. I am sure the quality is great, materials and execution, but still a lot to pay for something that is really more show than go.
it is expansive, but the quality is superb.. no doubt..
close box intakes been known to have a constant intake temperature..
there was a thread somewhere here testing both cone filters and close box. although cone filters been doing more power, but after 2-3 runs power drops to be same as the closed box, and later on it goes lower than closed box.
that was a dyno test i think between AFE and BMS or so, with hood closed.
so i'm sure the GruppeM would make a bit more than the AFE, constant power all day long, specially in Bahrain where summer reaches 45-50c on day time, and 40s at night..
