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 for most cars running faster than high 12's to mid/low 11s.  If you're car is still in the 13s I would recommend the <a href="https://www.ebay.com/itm/222759940527">CR42TS in a slightly hotter heat range</a>.

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!
