Is this something I should have for a 1992 300-E M103 9083 single cam six cylinder motor. I have no probles at this time and the car is like brand new (time capsule) I have been servicing the fluids and replaced the brake pads. Getting ready to flush the Power steering fluid and do a transmission filter service.

Anything I should look out for or buy to have would be helpfull.

thank You
