I'm just running 1 step colder plugs with my 75 shot, they should be okay with your 100 shot also. Try out the R5671A-8 4554 NGK Coppers. You will have to replace them often since they are copper, but I would just swap them out every time you do an oil change. They only cost like $15 for all 4 of them so that's good. Mine are gapped at .32

The problem is that u never know when they are gonna foul out. I wouldnt run 2 step colder when im not spraying. I found out that my car runs best on stock heat range with a 75 shot. For a 100 shot i would get atleast 1 step colder. I would try the v powers heat range 8.

Yeah, i've been running mine for around 600 miles already and only sprayed my nitrous maybe 4 times since i've had it. My plugs look perfectly normal, I just check mine every other time I spray just to make sure they are in good shape.

They will look fine but when u run colder plugs on ur n/a and then u spray u can foul them out and burn a hole in the piston. Thats why it good idea to swap them out when ur done sprayin.
