Use BR8ES. These are a fixed top NGK, non-projection type plug. These are a copper core cross-over to the factory Bosch W3DPO Platinum plugs. They cost $2 and are available at Advance Auto and several other local parts distributors.

If your going one hotter then use the BR7ES. If your not interested in the resistor plug then you simply remove the R. The OEM plug is a resistor type plug, but this is only to reduce radio interference..

I run these pretty hard so I've not had a fouling issue.

Who listens to a radio in a 930 though
