Default What gap for copper plugs? TR5 TR55
Trying to decide what to get, TR5s or TR55s. As far as I can tell the only difference is the gap on the plug. What do yall like to run for a gap and why? I know factory gap with iridiums is .040"

Truck in sig, basically stock.

My vote on the poll was with a TR6 in mind. I would recommend .050 gap.

I did search but most don't seem to post up the gap they're running.

If it is basically stock then I would run a stock heat range plug gapped to the stock specs.
