They have different part numbers so presumably there is a difference but it was not noticeable to me when I drove the car.Can't be a difference between an AFM from a 3.0 and a 2.5.
There are definitely differences, in both the fuel ECU and ignition control ECU.Come on there can't be any difference between a 3.0 & 2.5 Bosch system. Maybe the AFM is set one more sprocket? The displacement justifies no upgrades in the injection system. All parts work in both cars, I switched 2.5 to 3.0 & 3.0 to 2.5, ecu's, afm's you name it, and I've done this many times and there is "NO" difference. Part numbers, yea right?
