im just looking for opinions on the best plug to run in a 396 with a 100 to 125 wet shot? i think im down to either the 103's , 104's or the tr6's. thanks guys

I would think 103s for your setup. I personally run 104s and have no problem with them. Like $14 at your local auto store. As opposed to having to order NGKs or find a local speed shop that carries them.

 

well i have no problem getting the ngk's i just want to know which one will be better for me. I wont be running the nitrous very often so i need a good in between plug. one that will run good on nitrous but also run good on just motor. maybbe a step or 2 )at the most) colder than stock.thanks for your opinion
