I prefer .028 gap as required. I had a little hesitation when I gun the gas on my truck. Replacing the plugs fix that problem. Truck has power again. I also recommend a magnetic 5/9 socket. I put as required dielectric grease on the tip of the boots and Silicone lubricant on the rubber coil top sleeve to help future removals. ## Frequently Bought Together - OverstockDirect OEM Iridium Spark Plugs (6 pack) SP580X CYFS12YT4X - Motorcraft WR6135 Ignition Spark Plug Boot - Permatex 22058 Dielectric Tune-Up Grease, 3oz. - High Performance Dielectric Grease Used To Protect Terminals, Spark Plugs, Wiring And Other Electrical Connections Against Salt, Dirt, And Corrosion --- ## 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.us/products/280339937-oem-iridium-spark-plugs-6-pack-sp580x-cyfs12yt4x](https://www.desertcart.us/products/280339937-oem-iridium-spark-plugs-6-pack-sp580x-cyfs12yt4x) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-14*
