Multiquip 9807654716 Spark Plug BR4HS GA-6HZR HC-0649830

The Multiquip 9807654716 Spark Plug BR4HS GA-6HZR HC- is a genuine OEM spark plug designed for the GA-6HZR. This OEM-sourced component is built to the exact specification required by the GA-6HZR, ensuring a direct, drop-in installation with no guesswork on fitment. Sourced directly through Multiquip's authorized parts network, this plug is the same component installed at the factory, giving you confidence that ignition timing and combustion efficiency are maintained to the machine's original design intent. DHS Equipment stocks this part ready to ship so your GA-6HZR is back in service fast.

Key Features

• OEM Ignition Specification — Manufactured to the exact heat range, thread pitch, and electrode gap required by the GA-6HZR engine, ensuring correct spark energy and combustion timing.
• Direct Drop-In Installation — Threads directly into the GA-6HZR cylinder head using the original plug socket, with no adapters or rework needed.
• Confirmed Fitment for GA-6HZR — Verified against the GA-6HZR parts catalog under Multiquip part number 9807654716, cross-referenced as HC-0649830.
• Consistent Cold-Start and Full-Load Performance — A correctly spec'd spark plug supports clean ignition across temperature ranges, preventing misfires and rough running under generator load.
• Fuel System Integrity — Running the correct spark plug heat range prevents fouling and pre-ignition, both of which can accelerate engine wear and create unsafe operating conditions in power generation equipment.

A spark plug ignites the compressed air-fuel mixture inside the engine cylinder, initiating the combustion cycle that drives the engine. In generator equipment like the GA-6HZR, consistent spark quality is critical — a worn or incorrectly specified plug causes misfires, rough idle, hard starting, and increased fuel consumption. Left unaddressed, a failing spark plug places additional load on the ignition system and can cause incomplete combustion, leading to carbon buildup and potential engine damage over time.
