930 Track Sparkplug Recommendation
Looking for the best plug for 930 track use.
1980 930 Stock turbo .8 bar Stock CDI SSI Headers, no muffler I'm assuming a colder plug like the NKG BR8EIX is a good choice. Recommendations? And, what should the gap be set at for stock CDI. Thanks Jim 1980 930 1995 993 |

I've run stock plugs for years, no issues or complaints. $16 each from our host.

I use a Denso IW-24 which is their heat range 8 iridium plug. They also make a racing version of that plug but I've found the standard iridium version is pretty awesome.

Don't torture your poor little stock CDI with a resistor plug. It will just get even hotter than normal, and deliver less energy at the gap.
Why change from a 0.2mm platinum electrode to a .4mm copper electrode? Seems like the wrong direction to me. |

or use the IK-24 with a smaller 5/8" hex. Easier to change.

Thanks guys.
I'm bringing a 1980 930 back to life and want to update the plugs. My former mechanic used some Champion from a long time ago. The car has been idle for over 10 years so is getting the fuel system and mechanical go over before restarting. Lot's of opinions to consider here. Jim 1980 930 1995 993 |
