Key Features
- Genuine OEM Quality — Manufactured to original Genie specifications for the LSG 423 engine, delivering correct insulation rating, wire gauge, and boot fitment for lasting ignition performance.
- Direct Engine Match — Engineered specifically for the LSG 423 engine configuration, so the wire set installs cleanly without cutting, splicing, or adapting.
- Broad Boom Lift Coverage — Compatible with Genie S-series telescopic booms and Z-series articulating booms, including the Z-45/25J Bi-Energy and Z-45/25J DC variants.
- Ignition System Integrity — A complete wire set ensures consistent spark delivery across all cylinders, supporting smooth engine starting and steady power output under load.
- Operational Safety — Worn or cracked ignition wires can cause misfires, rough running, or unexpected shutdowns at height — replacing the full set restores dependable engine operation on aerial equipment where reliability is critical.
Spark plug wires carry the high-voltage electrical signal from the ignition coil to each spark plug, triggering combustion in the engine cylinder. Over time, the wire insulation can crack, harden, or arc, causing misfires, difficult starting, or inconsistent engine performance — symptoms that become serious concerns on a boom lift operating at height. Replacing the full set together ensures uniform ignition signal strength across all cylinders and eliminates the guesswork of tracing an intermittent misfire to a single degraded wire.
