Any advice would be appreciated.

There's also an R45S that has a slightly longer electrode that projects into the combustion chamber more. | | | | | Joined: Feb 2000 Posts: 987 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 987 | It has been almost 20 years since I ran an auto parts store. But even back then Non Resistor plugs where not real popular. My question is this, are they even available? I know in all the time that I sold parts we never ordered any. We might have had some old stock.
