One of the other members asked me what heat range plugs I was using in my cooupe. I've been using NGK BPR5ES Irdium race plugs but I also know that one of the prep manuals for Datsun Cherry (Rentille74 I think) notes ranges from 5 to 8. Iv not,suffered any detonation so stuck with the hotter / standard NGK 5 although I've given thought to going to a slightly colder 6 or 7.The A15 in my car runs 11:5-1 comp with a moderate cam , ignition advance is 38 degrees and I run 100 octane fuel.

So my fellow A-series racers what plug heat range are you using?
