Ngk 6720 BM6F Lawn Garden Spark Plug

Product Description

The NGK 6720 is a spark plug designed for outdoor power equipment and lawn and garden applications. It carries the OEM designation, meaning it meets the original equipment specifications for the engines it serves. The plug promotes complete combustion, which reduces emissions and helps prevent fouling on the electrode. Licensed technicians and service professionals working on small-engine equipment will find it a direct-fit replacement that supports reliable ignition and consistent engine starts across a range of operating conditions.

This spark plug is suited for residential and light commercial outdoor power equipment including lawn mowers, garden tractors, and similar small-engine machines. It is commonly used in seasonal maintenance routines where spark plugs are inspected or replaced to restore engine performance and fuel efficiency. The BM6F designation identifies the plug's heat range, thread size, and reach, making it easy to cross-reference against equipment service manuals.

Key Features

• OEM-approved specification for outdoor power equipment engines
• Promotes complete combustion for lower emissions
• Resists fouling for extended service intervals
• Supports easier cold and warm starts
• Long service life reduces replacement frequency

Compatibility

Designed as an OEM-style replacement spark plug for lawn and garden outdoor power equipment engines where the BM6F plug type is specified.

Installation Notes

Spark plug replacement on small-engine outdoor power equipment should be performed by a qualified small-engine technician or experienced service professional. Disconnect the spark plug wire before removing the old plug to prevent accidental engine starts. Use a spark plug socket and torque wrench to seat the new plug to the engine manufacturer's specified torque — do not overtighten, as this can damage the threads in aluminum cylinder heads. Verify the plug gap matches the engine specification before installation.
