Sorry Jim but it's to stinking cold outside to go out to the garage and tell ya what I'm using. I know they're Bosch, I'll check tomorrow, heh how did that brake line bleed go.

Jim I've switched between Bosch WR9FC and NGK BPR5S plugs, good luck with both. I kept fouling the J12 Champions.

If your plug is brown it's cause it's been up your ***.

It was a joke.
Seriously though, with todays gas you have to be 4-6 jet sizes too big to get brown colored plugs, the gas just burns too clean any more and plugs clean themselves[if they are the right heat range].

So buy a couple new plugs and lean the primary's a lil, as long as your timing is 1st set correctly.

I would use ngk, autolite or champion.
