Would purchase again. Good quality and value for the money. ### ⭐⭐⭐⭐⭐ Review *by G***R on 29 August 2017* as described!!! Did the trick!! ### ⭐⭐⭐⭐⭐ Review *by M***N on 21 January 2024* These pre-gapped plugs are great for your engine. It took me 1 hour to replace all my old plugs with these new ones in a V-8 Mercedes 550 engine. EASY. The NKG plugs are running smoothly and sometimes, as with these, small things can make a big difference. I had previously installed Bosch, but after 50,000 miles I felt they needed to be changed because I was seeing degradation in my fuel mileage. I will come back and update this review in 5,000 miles to tell you if and when my mileage has improved. I can already see a upgrade in engine performance just going about 10 miles. --- ## 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.kr/products/261588826-93911-lkr7aix-iridium-ix-spark-plug](https://www.desertcart.kr/products/261588826-93911-lkr7aix-iridium-ix-spark-plug) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-25*
