What plugs are you using, btw running boost. Last time i searched was not much out there maybe better luck this time.

GM replacement = ??? (need to take them out again)
NGK = NGK LTR6IX-11 looks about right but damn $9 a piece

 

Thoughts?

 

Talk to chuck at HHP or whatever it's called. He's got that info

 

I went ahead and got ngk iridium, now to see if i keep gap or make it smaller like i did with factory plugs.

 

I've heard bad things about running iridium and power adders, or is it just nitrous?

 

Brisk racing rr14s is what I have been running 150 shot nitrous 400hp/500ftlbs

 

you're only making 400 on a 150 pilled setup?

what kit are you running if you don't mind me asking?

 

I have been running iridums with boost on my truck for a year. It is daily driven and daily boosted. I have no issues at all.

 

maybe it's just iridiums and nitrous that's an issue, obvsouls boost is easier on things than nitrous

 

Platinums are a no no, many people run iridiums but I prefer a standard plug with boost.
