## Customer Reviews

### ⭐⭐⭐⭐⭐ great spark plugs
*by D***L on December 28, 2024*

we put the plugs in the race truck every year great plugs

### ⭐⭐⭐⭐⭐ Preferred plug for SBF w AFR185s & 100 shot
*by D***D on May 6, 2022*

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.

### ⭐⭐⭐⭐⭐ Five Stars
