Hi Guys,

My 2056 has heads threaded for 12mm plugs. The PO was running NGK DR8ES-L. That's a 19mm thread reach.

I was thinking of running a hotter plug, but can't seem to find a 6 rating in 12mm. And not sure if the 19mm depth is advisable. Would also love to find a plug with integrated terminal tips...as these are threaded but don't come with the terminal nut. How much could NGK really be saving by not including those!

Thoughts or suggestions?

Thanks!

I'm using the NGK DP8EA-9 in my 2270. They also don't come with the screw on tips though, so I borrowed them from another set of NGK plugs that I had that had them.

I am running are 12mm NGK DR7EIX Irridium. I think they came with the screw on tips.
