NGK Standard Spark Plug Box of 10 (CR4HSB)

NGK is known for making reliable ignition components that many manufacturers trust as original equipment. These NGK Standard spark plugs, found in their iconic yellow box, are a prime example of that proven technology. They're built to deliver dependable performance for a wide range of applications, from generators to trimmers and even some motorcycles.

Inside each plug, you'll find a pure alumina silicate ceramic insulator that's strong and helps with heat transfer, keeping things running smoothly. The 98% pure copper core is a big help too, offering excellent heat dissipation and conductivity across a wide range of operating temperatures. Plus, the trivalent metal plating on the outside isn't just for looks; it gives you superior protection against corrosion and makes them easier to install and remove down the road, preventing seizing.

NGK also uses triple gasket seals to make sure no combustion gases leak out, and corrugated ribs on the insulator help prevent flashover. These plugs are constructed for a longer life and consistent performance, making them a solid choice for keeping your equipment running right.
