what plugs should i run with a 100 shot of nitrous. i am currently running NGK tr55 on my engine but i am gonna be adding the gas to it and dont want to mess anything up. so what should i do? i have heard people talk about putting TR6's in their engines but just want to get some expert opinions

 

Everyone I have ever heard of runs the TR6's.

 

I use the Autolite AR103's gapped at .035 for a 150shot. I keep 3 sets on hand so I can change them out between runs. I haven't had any problems at all. The plugs always come out looking great.

 

Ah yes. Forgot to mention to gap them @ ~.035". The gap out of the box is larger if I remember.

 

anyone else?

 

I would also reccomend the TR-6s. I actually had them in my Silverado for about 5,000 miles or so just because it needed plugs and that's all I had kicking around. Some people say they will foul if you don't spray atleast once a week but I never had any issue like that. The only side affect to the TR-6s is you will notice alittle rougher of an idle. You should gap them around .035-.040. Every set I have ever bought came gapped at .038 right out of the box.

 

What about a 300 shot? What do you guys suggest?

 

Autolite 472

 

8s gapped at .035.

 

well i got a set of the tr6's and put them in and now i just have to finish wiring everthing up and i will be able to spray it for the first time. cant wait
