NGK Standard Spark Plug Box of 10 (JR8C)

NGK is well-known for providing reliable ignition components that have been a cornerstone in OE applications for decades. This box of 10 NGK Standard Spark Plugs, part number 5139, continues that tradition, offering dependable performance for your vehicle. These plugs are designed to meet OE specifications, ensuring they work correctly with your engine's ignition system.

Inside each plug, you'll find a solid 98% pure copper core that helps dissipate heat effectively and improves conductivity. The insulator is made from high-grade alumina silicate ceramic, which gives it superior strength and helps manage heat transfer. For easier installation and removal, the exterior features trivalent metal plating that resists corrosion and seizing. NGK also uses a triple gasket sealing design to prevent any combustion gases from leaking out, keeping your engine running smoothly.

This particular plug, the JR8C, is often used in motorcycle applications and is noted as being a hotter heat range than OE for some Suzuki models from 1988-1998. When you're ready to replace your spark plugs, this box of 10 from NGK ensures you have what you need for a complete tune-up.
