    if you using lfr6a they dont need gapping gap is correct if you use lf6ra-11 they will need gapping, just buy the stock ones and put them straight in.

    Always Gap to the MINIMUM tolerance. Itll help with starting and very slightly advance the timing. The fuel
    will burn completely and will help in overall preformance. Just like with valve timing, alwys wanna go for the lowest tolerance.
