Spark Gap

I have an OBS (EJ25) and can't find what the spark gap should be. Does anyone know?

Do not attempt to gap your plugs if your using platnum, or another precious metal, there is a high chance that you can rub the very thin layer of that metal off, making them worthless.

You dont really need the platinum/etc. plugs anyhow with the N/A motors.

I already went with platinum, and the factory set gap was between .044 and .045. Thanks for the input.

That was a qoute from above^^ And that is also why platinum and other alleged precious metal plugs aren't worth crap. Get regular NGK's or even copper and everything will run fine. Screw Iridium and all that jazz. My opinion.....Brian
