Frequently Asked Questions

How many YB05F spark-plug caps are required for a Honda CB450K or CB500T?

One YB05F cap is included. A CB450K or CB500T needs two plug caps total, but confirm the YB05F code, shape and clearance at both cylinder positions before ordering two identical caps.

Why should the YB05F code and cap shape be matched?

Different cap codes can use different angles, dimensions or terminal arrangements. Match YB05F and compare clearance around the cylinder head and fuel tank at each cylinder position.

Is the spark-plug wire included with the YB05F cap?

No. One YB05F spark-plug cap is included; spark-plug wire is not included.
