Preferred plug for SBF w AFR185s & 100 shot
Recommended by AFR, run them with no issues on NX 100 shot gapped at .035. The cut back ground strap and nickel plating are nice. The nickel plating with just a little anti seize makes removal a non-issue from aluminum cylinder heads. Recommend grabbing them when the price is right, sometimes it’s same or better than the standard 392X Autolites.
