Default g8 nitrous plugs?

Tryed searching around but couldnt find anything we put a nitrous kit on a g8 and swapped in autolite 103's and from what I was told it had a rough idle so they swapped in the stock plugs and it ran fine again. Does the g8 take a different plug then a standard ls1 for nitrous? Does anyone know what plugs to use that is copper and 1 step colder?

I believe tr6 would work pretty much the same as the autolite 103's as there similar just people prefer different brands.

TR6's will be fine. As long as the tune isnt aggressive.

Tr6's are the same heat range as the autolite 103's wont they make the car stumble as well? He put autolite 103's in and it drove bad wanted to stall etc...

Some cars respond differently to running a colder plug. You may be able to get it to run alittle better by working on the tune. I would not spray it on the stock plug. Arent they platinum?

Yes dave, the stock ac delcos are platinum which under no circumstance should they be used.

It takes the same spec as any of the LS style plugs. Shoot me a PM and I can send you an updated list of part numbers if you would like to try a different plug than the autolites.

Try The TR6. We have been using the BR7ef but if the car is already running rough I would try the TR6 over the BR7ef

It almost sounds like something else is going on...Try putting the NGK plugs in and see how it reacts.
