    NGK PLATINUM PLUGS

    Hi there I purchased an aftermarket set of NGK plugs PFR6B-11 for my 2001 STI & what I'm wanting to know is as an aftermarket plug do I need to change the gap or are they fine just to put straight in.
    I'm told the Subaru dealers plugs from NGK are at 1.2 where as the aftermarket plug is, I believe to be at 0.40?
    Cheers
