NGK Nickel Stock Spark Plugs Box of 4 (CR9E)

This is a box of four NGK Standard spark plugs, part number 6263, using the CR9E designation. These are the same kind of plugs you'd find as original equipment on many different kinds of vehicles, including motorcycles and snowmobiles. They're built with a pure copper core for good heat dissipation and conductivity, and the insulator is made from alumina silicate ceramic, which is strong and helps with heat transfer. The outside of the plug has a trivalent metal plating that helps prevent corrosion and makes them easier to get in and out when it's time for service.

NGK uses a triple gasket sealing design to make sure combustion gases don't leak out, and the corrugated ribs on the insulator help prevent flashover. These plugs are designed for long life and consistent performance, making them a solid choice for keeping your engine running smoothly. They fit a wide variety of applications, from Aprilia motorcycles to Arctic Cat snowmobiles and Kawasaki sportbikes.
