Key Features
- OEM Ignition Specification — Manufactured to Husqvarna's exact heat range and electrode gap requirements, ensuring proper combustion and engine protection across all compatible models.
- Direct Drop-In Replacement — Matches the original thread pitch, reach, and terminal configuration for a straightforward swap with no modification to the ignition system.
- Broad Compaction and Finishing Fitment — Compatible with the LF50L and LF60LAT forward plate compactors, BG245, BG244F, BG245H, CT36, and CT48 power trowels, the LX90 compactor, and the BT90 concrete screed.
- Consistent Engine Starting — A correctly specified spark plug delivers a strong, reliable spark at every start, supporting clean combustion and smooth throttle response under load.
- Protects Against Engine Damage — Using the wrong heat range plug risks pre-ignition, fouling, or overheating; this OEM plug eliminates that risk by matching the engine's original design intent.
A spark plug ignites the air-fuel mixture inside the engine's combustion chamber, making it the starting point for every power stroke. When a spark plug wears out or becomes fouled, the engine may be difficult to start, idle roughly, misfire under load, or consume more fuel than normal. Replacing it with the correct OEM-specified plug restores a strong ignition spark, supports efficient combustion, and helps the engine deliver consistent power — whether the machine is compacting a sub-base or finishing a concrete slab.
