Review: The plugs I needed for my pontoon. - Recommended for my 2020 Yamaha F90 4 stroke. Review: New Plugs Fixed My Rough Running Motor - My Yamaha VF90 was started running rough shortly after I got my boat back in the water after a long very cold winter. 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. ## Features - Trivalent metal plating provides superior anti-corrosion and anti-seizing properties - Corrugated ribs prevent flashover - Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer - Copper core aids in heat removal - Triple seals prevent leakage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081DQ73X8 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #38,639 in Automotive ( See Top 100 in Automotive ) #245 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car, Truck | | Core Material | Copper | | Customer Reviews | 4.7 out of 5 stars 89 Reviews | | Gap Size | 0.04 inches | | Included Components | NGK 90410 Standard Spark Plug LKR6E-9N - 4-Pack | | Item Highlight | Dependable nickel electrodes for cars, marine, and small engines. 20,000-30,000 mile reliable ignition. | | Item Type Name | NGK 90410 Standard Spark Plug LKR6E-9N - 4-Pack | | Item Weight | 6.4 ounces | | Manufacturer | NGK | | Manufacturer Part Number | 90410 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | 90410 | | Number of Items | 1 | | Thread Size | 12mm | | Top Material Type | Ceramic, Metal | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** NGK - **Core Material:** Copper - **Thread Size:** 12mm - **Top Material Type:** Ceramic, Metal - **Vehicle Service Type:** Car, Truck ## Images ![NGK 90410 Standard Spark Plug LKR6E-9N - 4-Pack - Image 1](https://m.media-amazon.com/images/I/51BU5ALFtFL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The plugs I needed for my pontoon. *by M***Y on July 25, 2026* Recommended for my 2020 Yamaha F90 4 stroke. ### ⭐⭐⭐⭐⭐ New Plugs Fixed My Rough Running Motor *by G***R on July 16, 2026* My Yamaha VF90 was started running rough shortly after I got my boat back in the water after a long very cold winter.
