Color of the spark plugs

  • Normally on the spark plug ceramic so that the ignition coil/plug connector does not bake and comes off more easily and without destruction the next time.

    I wrote that above.

    Okay, sorry, I meant rather that the thread is wetted.

  • The BERU grease is applied to the sealing lip of the spark plug cap.

    If you smear it on the insulating body of the spark plug, it then essentially sticks to the rubber of the spark plug wrench.

  • So, I've spoken to my consultant and the grease is actually going on the thread

    Everyone can put grease wherever they want.

    See attached photos of its packaging and extract from the VW instructions.

    It is also a fact that the Porsche workshop manuals from 996 to 991 never mention the use of any grease during assembly, whether for the spark plug cap or for the spark plug thread.

    Over the last five decades, I myself have screwed spark plugs in and out of numerous VW, BMW and Porsche engines, exclusively with light alloy cylinder heads, without using grease on the thread, without ever encountering any problems with seized threads, not even after 4 years of operation.
