Key Features
- Genuine OEM Quality — Sourced directly from Genie as an OEM part, this spark plug is manufactured to the exact electrode gap, heat range, and thread specification required by the Ford LRG425 engine.
- Direct Engine Replacement — Designed as a drop-in replacement for the Ford LRG425, this plug installs directly into the cylinder head without modification or special tooling.
- Broad Genie Fitment — Compatible with the GS-3384 scissor lift and Z-60/34 and Z-80/60 articulating boom lifts, covering key engine-powered models in the Genie fleet.
- Consistent Ignition Performance — A properly functioning spark plug delivers a reliable ignition spark at every firing event, keeping the engine starting cleanly and running smoothly under load.
- Engine Protection — A worn or fouled plug causes misfires, rough idling, hard starting, and increased fuel consumption. Replacing it on schedule protects the engine from unnecessary wear.
A spark plug ignites the air-fuel mixture inside each engine cylinder, triggering the combustion stroke that drives the pistons and produces power. On engine-powered Genie equipment fitted with the Ford LRG425, every ignition cycle depends on the plug firing reliably at the correct heat range and gap. When a plug wears, its electrode erodes, the gap widens, and the spark weakens — leading to misfires, difficulty starting, rough running, and reduced power output. Replacing a worn plug with the correct OEM part restores clean combustion and keeps the engine performing as designed.
