Key Features
- OEM Electrode and Heat Range Match — manufactured to Husqvarna's exact ignition specifications, ensuring the correct spark intensity and thermal dissipation for these compactor engines
- Thread-Ready Direct Installation — this spark plug matches the original thread pitch, reach, and hex size, allowing straightforward installation without modification
- Broad Compactor Fitment — compatible with LF75LAT, LF80LAT, LF100L, LF100LAT forward plate compactors and LG164, LG400 reversible plate compactors, as well as the LX90 compactor
- Consistent Cold-Start and Full-Throttle Performance — a properly gapped, correctly rated spark plug ensures clean combustion across all load conditions, from cold starts to sustained high-output compaction runs
- Ignition System Safety Compliance — using the correct OEM-specified plug prevents misfires and uncontrolled engine behavior that can result from an incorrect heat range or gap specification
A spark plug ignites the air-fuel mixture inside the engine cylinder, initiating the combustion stroke that powers the machine. In compaction equipment, the engine is subject to sustained vibration and varying load demands, which accelerates electrode wear over time. A worn or incorrectly specified plug causes hard starting, rough running, loss of power, and increased fuel consumption — all of which directly reduce the effectiveness of the compaction work being done.
