Over the years I have run J8's, AC's and latterly NGK's in a number of different WW11 truck engines.

I agree with you guys the old J8 just keeps doing it's stuff but I had some issues with hot starting.

The AC however gave poor results for heat resistance during running and this was in several jeeps !!, not renown for over hot running here in the UK , poor hot start as well.

I run the 216 on NGK and they run real hot inside a 12 cab engine bay with no problems at all,..... they get my vote for best all round performace.
