NGK Standard Spark Plug BPR4HS (Box of 10) for Select Aprilia, Honda, Kawasaki, Suzuki, and Yamaha 1971-2016

Fits select 1971-2016 Aprilia, Honda, Kawasaki, Suzuki, and Yamaha scooters, ATVs, and motorcycles, including PW50, JR50, and Scarabeo 50 2T models.

NGK Standard spark plugs (BPR4HS) are engineered as a reliable OE replacement for small-displacement engines. These plugs feature a solid 98% pure copper core for superior heat dissipation and conductivity, ensuring consistent ignition across a wide heat range. The high-grade alumina silicate ceramic insulator provides high dielectric strength and heat transfer, while the corrugated ribs help prevent flashover that can lead to misfires.

Each plug is treated with trivalent metal plating, providing long-lasting protection against corrosion and seizing in the cylinder head—an essential feature for air-cooled engines and powersports applications. The triple gasket sealing process prevents combustion gas leakage, maintaining engine compression and efficiency.
