The stock MAF sensor is transferred to the Dinan housing. There is slack in the 4.6 MAF sensor wiring. If not enough all you would have to do is splice in what you need.

Dinan products go through significant research, testing and development. I wouldn't use a larger diameter TB than the Dinan offering. Also, unless you can find a Dinan tune that takes advantage of the CAI, there will be very little improvement in performance. It will sound much better but that's about all.
