GEN III Spark Plugs

[Millsaps2]

Has anyone replaced the standard CPR8EA-9 plugs on a GEN III with an iridium replacement? I have not been able to find a cross reference for an iridium replacement.

For info:CPR8EA-9
C=10 mm thread
P=Projecting insulator
R=Resistor
8=Heat rate
E=19 mm thread reach
A=Special design
9=0.9 mm gap

So far it doesn't look like there is a 10mm iridium cross with a projector tip. There is a 12mm iridium plug but I think it would be a tough retrofit

Do stick with the new projector tip plug but don't worry about needing an iridium plug. If we had to remove the engine (like some trucks and cars) then the extended life may be worth it but the FJR is a fairly easy change. There is a recent thread that talks about plugs here.
