Got me somewhat worrying and curios, and so I went to an auto parts store and bought the same set of plugs. Guess what -- the set from the parts store is exactly the same as the one from Amazon. It looks exactly the same, all the dimensions are identical, the weight is the same, the resistance is the same. I have replaced a set which was installed 3 years ago and did 25000 miles on my Yamaha FJR1300, and it did not really need to be replaced. --- ## 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.es/products/281662041-4218-spark-plug-4-pack](https://www.desertcart.es/products/281662041-4218-spark-plug-4-pack) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-07-08*
