The Genie 84901GT Spark Plug is a genuine OEM component built for TZ-50/30 and TZ-50 trailer-mounted articulating boom lifts. Sourced directly through Genie's OEM supply chain, this spark plug is manufactured to the same specification as the part originally fitted to your machine. Cross-reference part number 84901GT against your machine's parts manual to confirm it is the correct plug for your engine configuration before ordering.
Key Features
- Correct Ignition Spec — Built to OEM specification, ensuring the electrode gap, thread pitch, and heat range match what your engine requires for consistent ignition performance.
- Direct OEM Replacement — Installs in place of the original plug with no alterations, keeping service time short and the job straightforward.
- Fits TZ-50/30 and TZ-50 — Confirmed fitment for Genie TZ-series trailer-mounted articulating boom lifts; verify against your serial number and parts manual before ordering.
- Consistent Engine Starting — A sound spark plug fires reliably at every start cycle. A worn or fouled plug leads to hard starting, misfires, and rough running that can interrupt work cycles.
- Genuine OEM Assurance — As a genuine Genie part, this part meets the original design intent — giving you confidence that the replacement matches the engine manufacturer's requirements.
A spark plug ignites the air-fuel mixture inside the engine cylinder, and reliable ignition is essential for smooth, consistent engine operation on a trailer-mounted boom lift. Over time, the electrode wears down, deposits build up, and the plug loses its ability to fire cleanly — leading to misfires, rough idling, hard starts, and reduced engine output. Replacing a worn plug with the correct OEM part restores proper ignition timing and keeps the engine running at the performance level the machine was designed to deliver.
