    Spark Plug Gap

    Time to do my plugs on Stage 1 AGU 1.8T.
    I have bought NKG V Power BKR7E (one step colder) but is 035" (0.9mm) gap ok.
    Pretty sure I use these all the time, but I keep hearing about gapping to 0.28''?
    Cheers

    Have heard 0.8 as well, just to add to the confusion.

    1.1mm is the general standard for plug gaps, though.

    For chipped cars the gap is .028" !!

    Any gap above that will affect your cars performance.

    If you have never gapped to 0.028" you are in for a real treat.

    So if I never changed or adjusted my spark plugs when Gav tuned the mk4 ecu then I should do it?

    I'd pull them out and check them Clif. The BKR7E only cost about a fiver each if you decide to replace them.
