    Hello all, does anyone know the MB recommended torque for W169 A150 spark plugs please?

    Have changed hundreds of plugs in my time on cars & bikes never used a torque wrench but doing the job on this car has caused so much build up stress I will be taking ever precaution.
    Made up a big mirror which hangs inside the engine compartment and going to follow someone elses excellent idea to remove the air box first as it looks so easy to do.

    Your Mercedes:
    C220CDI AMG Line Premium, SLR McLaren Roadster, SL55 & C32AMG
    20 newton meters should be ok.

    You dont need to remove the airbox, it would be easier to jack the car up at the front and do them from underneath.

    Its not a scary job at all, dont stress yourself.
