NGK Laser Iridium Spark Plug Box of 4 (CR7EIA-9)

If you're looking to keep your 2014-2017 Suzuki LT-A400F KingQuad ASi running smoothly, these NGK Laser Iridium spark plugs are a solid choice. They're designed as a direct OE replacement, meaning they'll fit right in and perform as expected for your ATV's ignition system.

What sets these plugs apart is the iridium-tipped center electrode, which is significantly harder than platinum and offers excellent durability. This means a more consistent spark over a longer period, helping your engine run efficiently. The pure alumina silicate ceramic insulator helps manage heat, and the trivalent metal plating on the exterior helps prevent corrosion and seizing, making them easier to remove next time. They also feature a platinum pad on the ground electrode for even wear, especially important in modern ignition systems.

You'll want to order these in a box of four to ensure you have one for each cylinder on your KingQuad.
