I need to change out from my original stock plugs. I want to turn some tr6 as plan to run nitrous but the nitrous will only be run very rarely. I would run 75 to 125 shot range when do use it. So will the tr6 be ok for daily use. What should I gap them down to .035 or .040 rather than .050?

 

I have run them for a couple of years now. They don't make it 60-80-100k miles like some new oem plugs, but I did not have to change them often.

I generally change my plugs anytime I am working on something major, especially ignition.

I have not had a set foul out on me.

 

i ran them and they worked fine for me

 

Ok as likely won't be hitting them with spray till next year and then just occasional nitrous fun. So what should I gap them too..

 

.035 seems to be fine
