Spark plugs on a 75 shot on my LS4 engine. I was wondering if I need to get new plugs or re-gap the ones that I have? or not do anything since it is a small shot. I looked all over trying to figure this out but I can't. I seen the spark plug chart in the sticky but honestly cant understand it . If anyone could share some insight it would be greatly appreciated !

I was also wondering about window switches. I looked around and seen the descriptions on what they do. I just wanted to know if they are programmable so only activate in 2nd and 3rd? Do some do and some don't? or do I need some kind of controller to do that? I saw a $60 window switch from summit . I Don't want to fork out 2-300 for a controller but if I have to I will.

Edit: are my stock ones ok? or should I buy colder ones like these one step colder = safer? Some guys use 6 on lightly modded cars, i figure 7 should be good for a 75 shot... any thoughts?

Thanks for reading, sorry for the noob-ish questions I just could not find them anywhere :/

Not many people on the boards on weekends, Monday morn ull get some answers for sure, as for plugs I've learned u have to go at least a step colder for nitrous, probly. Step for 75, 2 for 100+
