the Z1 SMIC. Harry tuned my car couple days ago, but Id just like to add something. I have the stock front facia and I still have the air ducts on the Side mounts. I did shave the side air ducts to lessen the restriction but there is still some restriction on air flow when the car is not moving, the benifit is of coarse when the car is actually on the road, moving. Im sure if I didn't have the side air ducts on when we did the dyno, the Z1 intercoolers would have provided a cooler temperature in my opinion.
