Well I am not sure. The manifold has all the holes for the stock stuff, but it doesn't have the clearance for the after AEM fule pressure regulator. I don't know what they did, but it did not have enough roon for it, you might have the room if you use the stock FPR but with what I am doing I don't think that the stock FPR will be sufficient. Anyways I am going to get with my sales guy and get it straightened out.
