Reckon they don't drug test where he works....

I run the 6R12's. Never had a problem. I do have a set of NGK's in my box that I've never used...

Plugs is plugs as long as they fit in the hole and don't get whacked by the pistons. Their job is simple. Only critical thang about 'em is the heat range.

Now. Somebody start an oil thread. ..

I run Champion RA6HCs tho the RA8HCs are closer to the stock heat range.. Baggers have Tmax so no issue with screwed up ion sensing..

Every time I check mine, they look excellent, still running OEM stock plugs.
Whenever I change, the same will fill the hole again.
OP, how do yours look? How many miles? Any problems?
