Tiny yellow specs on spark plugs, Zex Hyperformance plugs.

Someone verify this for me, I believe that means I'm burning up some aluminum or the internals itself. Most likely running lean or could it be a timing issue? I cannot adjust the timing of the car due to 03 Accord, coil on plugs, no dist here.

nitrous application. I'm going to back down the shot and I have a GReddy fuel pressure gauge now to monitor it. I'm also hitting a dyno to check if I'm running lean or not next week.

I pulled those Zex plugs out and put back the stocker Iridium plugs.

 

ditch the zex plugs. total crap.

 

I agree, the car had a small spit here and there at idle, now its smooth.

my problem is I cannot find that stock iridium plug two steps colder. anyone got an idea NGK: IZFR6K-11, I would want a IZFR8K
