Same spark plugs?

  1. #1
    I'm going to be doing a mini service on my GTI with J4 head, but will be soon changing to my JP4 206 1.6 16v head.

    Obviously i don't want to change my spark plugs and then change heads and have to buy more. Waste of money in my opinion, so was wondering if they are the same?

    If they are i'll go buy some now If not, i'll wait

    Thanks,

    Andy
