NGK Laser Iridium Gap Size

[NickJBill]

What should gap be for this? I’m looking to run a Bootmod3 91 octane Stage 1 tune and I have the following work done - Vrsf intakes, FTP charge pipes and j pipe, Vrsf top mount intercooler, Mishimoto oil catch can.

I’ve heard anything from .018 to .022.

Any help would be great!

Thanks all.

On the BM3 web wiki they recommend gap.

If you'll be running less than 30psi of boost we suggest a 0.022-0.023" gap. We've gone to 0.018" on some cars with 30+psi but in most cases that isn't needed and will cause rough idle in some cases. In most cases though we just go with the 0.022-0.023" gap and call it a day.
