Why waste your time? The throttle body spacer will do NOTHING on a mpfi engine. It does help on older carb vehichles as well as old TBI engines where it actually does help atomize the fuel. But all it will do for your 4.0 is make a funny little whistling sound, as the injectors are already placed correctly to atomize the fuel before going into the cylinder. It will slightly broaden the torque range down low, while dropping horsepower at the top end.
