i tried to get more picture there to let you guys know about the structure. I think the the GrurppeM CIA is under certain premise to compare with OEM one. the key benefits are larger flow of air and won't suck heat from engine bay. I am living the city the temp will increase to 40'C at summer. So cool air is very important. If i back to Toronto, i'd go for AFE2 CIA. However, after the change i notice clear increase on power and torque. Althought it may not be very significent but clear response is good enough to me.
