The TROY-BILT 98079-56846 is a BPR6ES-type spark plug designed for small engine ignition in outdoor power equipment. The spark plug fires the air-fuel mixture in the combustion chamber, initiating each power stroke in a gasoline engine. This part is sourced as a genuine TROY-BILT replacement component, making it a direct fit for the engine it was specified for. Licensed small engine technicians and experienced equipment service techs are the typical installers, though mechanically inclined DIYers familiar with small engine service routinely handle spark plug replacement as part of seasonal maintenance.
This spark plug is suited for use in TROY-BILT lawn and garden power equipment powered by small gasoline engines. Common applications include walk-behind lawn mowers, self-propelled mowers, and similar outdoor power units where a BPR6ES-style plug is called out in the engine specification. Spark plug replacement is a standard tune-up task performed at the start of each season or after the interval specified in the equipment service manual.
Designed as an OEM-style replacement spark plug for TROY-BILT lawn and garden power equipment specifying a BPR6ES-type plug. Refer to the equipment model's service manual or parts diagram to confirm fitment before installation.
Spark plug replacement on small engines is performed by qualified small engine technicians or experienced equipment owners. Always disconnect the spark plug wire and allow the engine to cool completely before removing the plug. Use a properly sized spark plug socket and torque the new plug to the specification listed in the engine manufacturer's service manual. Do not overtighten, as this can damage the cylinder head threads.
