Installation Information:
Allow the engine to cool completely before servicing. Disconnect the battery or spark-plug lead to prevent accidental starting. Thread each plug by hand first to avoid cross-threading, then tighten it to the torque specified in the equipment owner’s manual.
Important Fitment Notice:
Spark-plug requirements, gaps, and torque specifications vary by engine and model. Generac has revised the recommended spark plug for some engines, so matching an older cross-reference number alone does not guarantee compatibility. Confirm the required plug type and gap using the latest owner’s manual or parts list for your equipment before ordering.
