NGK Laser Iridium Spark Plug Box of 4 (SIMR8A9)

NGK Laser Iridium spark plugs are a solid option for many Honda motorcycles, offering a great balance of performance and how long they last. These are built to meet original equipment standards, meaning they're tested to ensure they work right and hold up over time. The center electrode uses an iridium alloy, which is much harder than platinum, giving you a more consistent spark and longer life. Plus, the pure copper core helps keep the plug from getting too hot, ensuring reliable starts even in tough conditions.

You'll also find a platinum pad on the ground electrode. This helps it wear evenly, especially in modern ignition systems, and contributes to a stronger spark. The pure alumina ceramic insulator is strong and transfers heat well, while the trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later. This set comes in a box of four, perfect for most 4-cylinder applications.
