NGK Standard Spark Plug Box of 10 (BPR4HS)

NGK Standard spark plugs are a proven OE cornerstone, offering reliable performance that customers have counted on for decades. These plugs are built with a solid 98% pure copper core for excellent heat dissipation and conductivity, helping to maintain optimal operating temperatures across a wide range of conditions. The high-grade alumina silicate ceramic insulator provides superior strength and dielectric performance, while triple gasket sealing prevents any combustion gas leakage. This makes them a solid option for a variety of applications, including motorcycles, ATVs, and small engines.

The trivalent metal plating on these NGK plugs is notable for its superior anti-corrosion and anti-seizing properties. This means they install and remove more easily, even after extended use. The corrugated ribs on the insulator help prevent flashover, ensuring a consistent spark. You get a box of 10, which is handy for those jobs where you need multiple plugs, like on certain multi-cylinder engines or for keeping spares.
