This is a full set of 6 plugs for a GN.  Brand new in the box

These are the CR's so they have the thicker electrode to put up with higher cylinder pressures and temps. Along with periodic hits of detonation.

This heat range is correct for stock cars with minor upgrades to modded cars with basic bolt-ons. I recommend these plugs for bone stock through basic bolts on's. Anything faster than high 12s, I would recommend the slightly colder CR42TS most of the time.

Shipping is quoted for the lower 48 and I will combine shipping for this and any of my other items.  Just add everything to your cart and choose 'ask seller for a total'. I'll weigh it up and get you a discounted price for everything.

I ALWAYS leave first feedback as a seller and I ship promptly!
