Gap on a set of autolights

[junior92]

I need to know what gap to run on the autolights. Out of the box they are at .21.

Stock gap is .035". If you are running stock boost I'd go with that.

Brad, which Autolights? 63's? And I forget, does your CSX have an MSD (or other) box on it? Stock gap should be no problem with a strong ignition.

+1 to start with .035" if it works great, if too much boost and spark gets blown out try less.

I run a msd box. Autolight ar51 they come gaped at .21 out of the box. They are the back cut plugs. I have chaps gaped at .28 in the car now. Ranning a holset hx35 at around 18 for now but will b up around 25 psi later.

If the .28 works OK start there
