I have some Denso Iridium plugs for my 96 Eclipse RS-T and would like to know what you guys Gap your spark plugs at for our turbo charge 420A's?

use .30 as a starting point and then some people begin to experiment with increasing it little by little until they start misfiring and what not. that's usually the accepted gap though. next time use the search function, it will pull up lots of results.

.035 that's the number I got from a while back. Worx fine for me, maybe I should try going lower never tried.

I found this out: up to 16 psi, gap the plugs at .030"; more than 16 psi boost, set it to .028" Right now, I got mine gapped to .030", running 15 psi daily. It seems to work the best.

HadesOmega, I see from you signature pic that you autoX. What do you think of it? That's something I'd like to get into. I went to a local Solo II recently, a got to ride in a couple of runs. I never knew our cars can handle like that!

8 psi gapped at .035 working nicely...

.035 here and as indicated by HRC.

BTW, NGK BKR7's come pregapped at that setting.

even if they do come pre-gapped check them cus mine cmae at like .045 instead.

Of course! :-)

Where do you guys order the 7e's from? They dont sell them anywhere around here. I have been using the stock heat range. They have worked fine.

Hehe I don't think 7e's make much of a difference. I just put my 6Es back in cuz I broke my 7Es :( and it seems to run smoother now. I guess 7Es are good if your running a lot of boost.

I've always ordered them from Advance Auto PDQ. They have to order them, but it only takes a day. Only $1.29 apiece, can't beat that!
