some models may because of years,different smog controls.My mechanic had to change alot of stuff from my 99 motor to a 97 e class motor.In some ways its better,because i have alot of stuff missing, that i did not need.Just make sure wiring is new or fresh.I would have loved to bought a 3.6 m104,and changed computers.
