The BRIGGS STRATTON 71s is a shop pack of 24 RC12YC-style spark plugs designed for small engine applications in outdoor power equipment. Each plug delivers reliable ignition performance in the combustion cycles typical of single-cylinder and twin-cylinder lawn and garden engines. This pack format is intended for dealers, service shops, and technicians who perform high-volume tune-ups and seasonal maintenance on walk-behind mowers, riding mowers, and similar equipment. Having 24 plugs on hand reduces sourcing time during peak service season and keeps the bench stocked for back-to-back jobs.
This shop pack is used in lawn and garden service environments where RC12YC-cross spark plugs are called for. Typical applications include residential and light commercial walk-behind mowers, riding tractors, and other small engine equipment serviced by outdoor power equipment technicians. The bulk pack format suits independent repair shops and dealership service departments that routinely process multiple units per day.
Designed as an OEM-aligned spark plug replacement for BRIGGS STRATTON small engines used in lawn and garden power equipment requiring the RC12YC plug specification.
Spark plug replacement is performed by qualified small engine technicians and knowledgeable outdoor power equipment service professionals. Disconnect the spark plug wire and allow the engine to cool completely before removing the old plug. Use a spark plug socket and torque wrench to seat the new plug; follow the engine manufacturer's torque specification found in the service manual. Inspect the plug gap before installation and adjust as specified by the engine manufacturer.
