I currently sqeezing NX Wet Kit (50shot) on my ride and I got the ZEX Spark Plugs Part# 82003 (Turbo and Nitrous Application) and I used a full tank of gas and a whole bottle of N2O 2 weeks ago, while using the ZEX spark plugs I noticed some really rough start, rough idles and little backfires, so I thought it's normal...

And this week when I start my ride, it seems like when I turn the key to start, it had this 1sec delay before it actually starts, so I thought it's normal, about 3 days later my CEL goes off, I took the ECU fuse to reset, but after about 20min driving my CEL goes off again... I took the ECU fuse again one last time but it didn't fix that problem...

So yesterday I changed my spark plugs (pictures below) and either it's overheating, is it because this week Las Vegas weather reached 100+ and 2weeks ago it was only low 80s?, or the spark plugs are P.O.S. and is Detonating?

I got my DensoIridium IK20 spark plugs back and it starts quicker now, the idles smoother, and I got rid of that CEL...

If you guys running Nox please let me know what type of spark plugs you guys using, how long you used them, part numbers and some feedbacks please!... and where to buy!

Thanks for the help you guys!

mine seem to be still working fine, i do notice a little less power running all motor and no N2O on them specially when its hot outside. but ive no CEL's or starting problems. But as far as the way they look, id say they are similar to yours in color from the burn.

yeah I've seen that thread...

I'm running the ZEX Nitrous and Turbo Spark Plugs, they are great on high RPM and or squeezing N2O but my CEL's going off, and it's misfiring...

that NGK Spark Plugs 2 steps colder? and you think how long can the NGKs last until you change them?

Thanks man, much appreciated!

I was using the Denso IK20s and I had no problem with the CEL...

I dunno what's wrong but everytime I put the zex spark plugs (Part# 82003) my CEL goes off! I kinda like it too, it pulls really hard when I got it on...

but i'm using the regular IK20s now and seems like I don't have any signs of detonation... the pull is not as hard as the zex but... this will do... I only squeeze every other day anyway...

and now i'm selling my NEX and Purge Kit... i'm boosting soon
