Spark plugs and Meth

[Bleu]

I'm building up a stealth I bought with 13ts and 550cc injectors. I plan on installing meth injection because the stand alone ECU has water injection support. The problem I'm running into is I plan on pushing about 20-22psi if I can and my first thought was to run 2 steps colder but would that be neccessary with the water meth? Also, its really hard to find resistor coppers 2 steps colder. I can't find BKR8E's anywhere.

Any information on the subject or even a open discussion about which plugs to run is welcome.

Decided with BKR7Es I'll probably gap them to about .028-0.29. I'll post back here with results in a few thousand miles I guess.

For 13Ts your power doesn't warrant 8's, I would stick with 7's and the NGK BKR7ES are great. It is all you will need.

Yea, that's what I figured. The funny thing is the motor had 8's in it already and I was just tempted to leave em there since they look pretty fresh.

The 7's should do me fine though

I wouldn't do 8s on 13ts, just not enough power/heat to keep them from fouling. And remember, to read a plug to see if it is too hot or cold the lean or rich foul ring is all the way down at the base of the ceramic nose, not at the top where you can easily see. You have to get a bright light and look down into the plug. If there is any black ring at the bottom, it's too cold or rich, there should be a thin beige ring at the bottom.

Thats really good information that I did not know. Thanks again!
