i installed my zex kit and got colder plugs (ngk bkr7e) and i've had the plugs in for maybe 2-3 days , i havent shot nitrous yet but i was about to for the 1st time and i was checking them before and was gona check them after a quik run, but i need somone to tell me if my plugs look ok because theres white on the matel thing over the point. its not crusty or anything but im not sure if its ok.. this picture is of the plugs after 2 days , havent shot nitrous yet.

UPDATE-(cant post more than 5 a day when trail user) shot the 55 shot for a quik run, plugs look the same, actually i only checked the 1st one.. has anyone had problems making a good thread in there intake for the nozzle? i've made 2 holes had to cover the 1st one.. no matter what i do the hole is to loose and seems almost stripped no matter how carefully i make it/tap it and screw it in, my aem intake is so thin it makes it hard... i think i need a larger fitting i can screw the nozzle into in the intake. anyone done this?

get a picture without the flash..it looks kinda white in this picture
black=rich
white=lean
brown=right

 

Just a lil tip. You may want to invest in an adjustable fuel pressure regulator b/c I had the same situation w/ my nitrous kit. I ran the 55 shot (wet) and the plugs were almost black so I changed out the nitrous jet for the next biggest and they kinda looked like yours does there. But they were only that way after shooting the nitrous not before.

 

That sparkplug looks normal. You could run a hair richer, but its ok. On the bottle you will run a little rich anyway. The companies jet the kits a little rich as a safety margin so you dont blow your engine.

 

heres what they look like after a few shots of n20 - what do you think? look ok?

 

Looks like they are tan-colored right now. Everything is fine.
