Description
The NGK BPM8Y V-Power spark plug is designed for small engines and outdoor power equipment, delivering improved ignition performance through its V-cut center electrode. This design helps the spark form more efficiently, resulting in quicker starts, smoother operation, and reduced fouling—ideal for chainsaws, trimmers, and other lawn equipment.
