Great value, plus fast delivery by Amazon. ### ⭐⭐⭐⭐⭐ Better than Bosch *by B***K on May 5, 2025* I never really cared for Autolite plugs until now. I was using OEM Bosch plugs in my BMW R1100RS motorcycle and was experiencing idle and acceleration issues. The plugs tested good, but a recent article I read recommended these plugs. Problem immediately was resolved when I swapped over. ### ⭐⭐⭐⭐⭐ Short Term Looks Good *by P***. on May 27, 2025* Cannot comment on their longevity, as I just bought them for my Honda NC-700X motorcycle. The OEM (I think) was NGK something or other, which cost $18 to $30 EACH!! These are also iridium and cost about $5 each. Bike started right up and runs great. --- ## 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.pl/products/1253005-autolite-iridium-xp-automotive-replacement-spark-plug-xp3923-1-pack](https://www.desertcart.pl/products/1253005-autolite-iridium-xp-automotive-replacement-spark-plug-xp3923-1-pack) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-24*
