NGK spark plug B9HCS short thread NOS | Yamaha

B9HCS spark plug with short thread suitable for various Yamaha moped, moped or small motorcycle models.

The spark plug is intended as a replacement for vehicles that require a spark plug with the designation B9HCS and short thread.

Thanks to the short, slanted / flat electrode, this spark plug is also suitable for high-compression engines where the piston protrudes far into the combustion chamber. The only difference to the B9HS is the electrode.
