Nitrous spark plug recommendation

[98toreadorLSC]

I'm going to be ordering a nitrous kit for my 98 Mark and was wondering what kind of plugs would be best for it. Ive heard you wanna go with a colder heat range and what not but any recommendations??

Rule of thumb when using nitrous is stick with a plain copper plug. Nothing to blow off the plugs if a problem. Also you will need to tighten gap and knock timing down. Again rule of thumb is 2 degrees for every 50HP. Running a heat range cooler or 2 is in the cards too. I have AR94's I think in mine which are an "autolite racing" plug hence the AR name ,which are 2 steps colder. These are clipped from autolite. I have no problems with them NA at all also.

AR94s are my suggestion as well. I ran them with nitrous for quite a while with no issues, and no fouling in daily driving as well. At minimum Autolite 103s, which are 1 heat range cooler than stock.

NGK TR6's copper gapped tighter. I have used these with no issues on a 125 wet shot (rated at the wheels).

22c's would be a good one... 12c's if you are going extreme with the Nitrous.
