Let me start by saying that if you are thinking of saving some money and going with the Summit Racing aluminum radiator, dont. I have already spent enough that I could have purchased the one from arizona z car, and I still dont have it done. If you want the details of what has been involved so far, send me a PM, but trust me when I say it is not worth it. The latest issue is that the water inlet neck is right next to the mass airflow meter. By removing the mounting plate, I can make enough room to get the hose on the inlet neck. In order to mount it back onto fenderwell, I will have to make some major modifications to the bracket. I would prefer not to destroy the mounting bracket just to make this thing fit. My question is this: Would it be ok to let the intake couplers hold the MAS in place? It is held in place pretty well by the hoses, but I figured Nissan mounted it solidly for a reason. Will vibration be an issue? Will it work?

I think it would be better to mount it solidly. The extra movement of it just being mounted by the hoses might cause the hoses to wear. Oh, and it's not a MAS, simply and AFM (Air Flow Meter). And being a AFM rather than a MAFS, it's much heavier and would probably put extra stress on the hoses. Our cars EFI systems weren't sophisticated enough to have a MAFS.
