    Turbo Spark Plug Gap

    Hey guys,

    I have a 1987 325i M20B25 with a turbo. my question is should I keep factory spark plug gap or would I need to run a wider or small one. I am new to turbo cars so just looking for some help. Thanks!

    depending how much boost and kind of ignition system normally you run colder plug and smaller gap

      What would be considered colder plugs? and the boost is maxed out at 10 PSI. Sorry for the questions just completely new to all of this lol
