Just wondering if AC Delco made a cold plug for our trucks. I think i'm gonna get rid of the NGK TR-6's. They've been giving me nothin but trouble. Will it be safe to spray nitrous with the stock plugs or do i really need cold ones?

 

Try the R43 LTS. That is what I run with the Whipple. Actually I run an "MR" but the M just stands for marine. I would never run a platinum with juice or forced induction.

 

My Whipple instructions recomend using an AC Delco platinum plug. I am using AutoLite 104s right now though. I agree with L-EATER though and would noe use a platinium with power adders - things get pretty hot in there.
