At first it ran fine, but after about 1.5 hours of run-time, it started missing. I use a gasoling additive (SeaFoam) every time I fill it so I wasn't sure why it started running rough. I topped off the tank with new fuel and took it out and ran it at high speed for about 25 minutes thinking it would clear the lines and plugs. Not so! Still running rough. Made the decision to change the plugs with these new plugs and it cleared up the problem. Runs great now! They were the perfect fit and installing them is super easy on my particular motor. It's an easy and inexpensive fix for an annoying problem. ## Frequently Bought Together - NGK 90410 Standard Spark Plug LKR6E-9N - 4-Pack - Yamaha New OEM Primary Fuel Filter Element, 6D8-WS24A-00-00 - Yamaha New OEM Oil Filter Cleaner Element Assy, Marine/Cycle, 5GH-13440-71-00 --- ## 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.pt/products/537935992-ngk-90410-standard-spark-plug-lkr6e-9n-4-pack](https://www.desertcart.pt/products/537935992-ngk-90410-standard-spark-plug-lkr6e-9n-4-pack) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-09*
