I run NGK Tr6's in my Camaro. Will those be cold enough for Nitrous on the 5.3L truck?

 

i ran tr55 iridiums in mine. when i went to the 175 shot i went to the tr6 iridiums.

 

i think they say no iridiums since they are so hard. they will outlast the piston in that event. i ran iridiums and had my best runs with them. ran then for 4 months with no problems.

 

Cant go wrong with NGK-TR6 and thats what most use. They are cheap too!

 

i run the stock replacement NGK conventional plugs in mine, no problems. by conventional i mean they arent iridium or platinum, etc. as long as they'll spark, they are good enough.
same set of plugs for about a year and a half spraying a few times a week CHIP

 

i run the TR6'S with a 100 shot on my 5.3 and i have had absolutely no problems with them. i ran the TR55's before the nitrous.
