NGK TR6 Plugs - Gap?

Anybody have a suggestion for the gap on these plugs? I am currently using .50 w/Nology wires but can't seem to find the exact specs.

TR6's Max gap is .043

Normally this plug is used for NOS or FI apps.
Tends to foul in a stock or H/C engine.

thanks for the info - I gapped at .050 after going to NGK's website and this is what they recommended. I am going to pull them in a week and see what they look like.

Np. TR55's are normally .050-.055
Not sure what they put online. Standard LS1 gap is in that range.

Talked to NGK techs directly before I tried TR6's once and they didn't like me going past .040 and said anything past .043 is bent to far and out of spec.

Re: NGK TR6 Plugs - Gap? (MelloYellow)

I've seen the same results with the TR6 plug...gapped below 40 is ok but above is more risky. I installed a set that I gapped to 42 and I burnt one of the electrodes clean off...this is with some nitrous use, though. I gap them to 38 without any problems now.

Thanks
