HOT plugs OK in HIGH C/R engine?
OK I ran into a guy on this board who was running High C/R pistons (12.0). He Hasn't had a smog check yet, BUT some guys including me use the NGK extended reach HOT plugs (part number NGK ZFR4F-11) with lower FP to pass. Is it possible to rund these plugs with the High C/R. I would think there might be a problem, but I wanna hear from you guys. Thanks!

It depends on how much heat(power) you are going to put on the plugs. If you driving in stop and go traffic all the time it's not a problem. If you plan to break the land speed record then you are going to have major problems.
