Highly recommend these plugs. ### ⭐⭐⭐⭐⭐ great spark plugs *by D***L on 28 December 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 6 May 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. ## Frequently Bought Together - Autolite AR3923 High Performance Racing Resistor Spark Plug, Pack of 1 - Valvoline VR1 Racing SAE 60 Motor Oil 1 QT - WIX Filters - 51061R Spin-On Lube Filter, Pack of 1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/443289120-autolite-ar3923-high-performance-racing-resistor-spark-plug-pack-1](https://www.desertcart.fi/products/443289120-autolite-ar3923-high-performance-racing-resistor-spark-plug-pack-1) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-08-18*
