Overall, the driving experience is more powerful and responsive compared to the OEM plugs. Highly recommended Review: Great plugs !!! - Had to do a plug change on my Ram pickup.

Plugs work great . Happy with purchase . ### ⭐⭐⭐⭐⭐ Expensive. Work fine, no noticeable difference e *by B***N on 7 June 2025* The gap wasn't 0.044. Its was closer to 0.041. That being said, the stock plugs I pulled out measured 0.042. Rather than mess around trying to regap 16 spark plugs perfectly I just installed them as is. I changed the plugs at 144 000km and notice almost no difference in sound or driving. They came well protected. These plugs are kind of expensive. I bought them for $250 Ca and their price seems to just keep going up. The drivers side on my 2018 ram 1500 sucked to do, even with the swivel socket. ## Frequently Bought Together - 16 pc NGK Iridium IX Spark Plugs compatible with Ram 1500 5.7L V8 2011-2021 - GEARWRENCH 3/8" Drive 6 Pt. 5/8" x 6" Magnetic Swivel Spark Plug Socket - 80546 - 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.hk/products/512466008-16-pc-ngk-iridium-ix-spark-plugs-compatible-with-ram](https://www.desertcart.hk/products/512466008-16-pc-ngk-iridium-ix-spark-plugs-compatible-with-ram) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-10*
