Spark Plugs: Green Plug 4028

[NGK BP5EY-11 Spark Plug Green Plug 4028 ngk bp5ey-11-4028]
A 90° groove is machined into the center electrode, making it easier for sparks to fly.
Because the spark occurs further out from the center electrode's periphery, the quenching effect of the electrode is reduced, improving ignitability.
This improves performance during starting, idling, and acceleration.
