Boine Ignition Coil Set for Kawasaki FH-Series Engines, 2-Pack — Direct Fit, Restores Spark

These two Boine ignition coils replace worn units for a range of Kawasaki single-cylinder engines, restoring spark consistency and reliable starts.

If your small engine is slow to fire, misfiring, or cutting out, a degraded ignition coil is often the culprit. This 2-piece set from Boine is built to fit many Kawasaki FH-series engines and drops into the original mounting points without modification, offering a cost-effective way to renew ignition performance on lawn mowers, pressure washers, generators, and other outdoor power equipment.

Which Kawasaki engines will these coils fit?

Boine designed these coils specifically to match the mounting, gap, and electrical characteristics of multiple Kawasaki OHV engines in the FH family. They are compatible with both the V-series and D-series model ranges listed below, making them useful for fleet maintenance or backyard repairs.

• Fits models: FH381V, FH430V, FH480V, FH500V, FH531, FH541V, FH580V, FH601V, FH641V, FH680V, FH721V, FH601D, FH641D, FH680D, FH721D.
• Direct replacement part cross-references: 21171-7001, 21171-7003, 21171-7006, 21171-7007, 21171-7013, 21171-7018, 21171-7022, 21171-7024, 21171-7026, 21171-7037.
• Designed for single-cylinder, air-cooled Kawasaki engines common in outdoor power tools.

How does replacing the coil affect engine operation?

A fresh ignition coil provides a stronger, more consistent high-voltage pulse to the spark plug, which improves ignition timing reliability and combustion quality. That can translate to easier cold starts, fewer misfires under load, and steadier idling without changing carburetion or other ignition parts.

• Improved spark energy reduces hesitation and backfiring during throttle changes.
• More consistent firing across rpm range for smoother operation.
• Can resolve symptoms previously attributed to carburetor or fuel issues.

Is installation difficult and what tools are required?

Installation is straightforward for anyone comfortable with basic small-engine maintenance: remove the engine shroud, disconnect the spark plug wire, unbolt the old coil, set the air gap, and fit the replacement. Boine coils are pre-tested and manufactured to the same mounting hole locations as OEM units, so no case or ignition timing adjustments should be necessary.

• Tools: socket/ratchet or screwdriver, feeler gauge for setting the air gap, torque wrench recommended.
• Safety steps: disconnect spark plug wire and remove spark plug before working.
• Typical install time: 20–45 minutes depending on model access.

What are the build characteristics and support options?

These Boine coils are manufactured to provide consistent electrical performance and are inspected before shipping to minimize early failures. The seller provides after-sales support for fitment or operational questions, so you can get help if something doesn’t align with your engine during installation.

• Each package contains two ignition coils for convenience or to service multiple machines.
• Pre-shipment testing reduces initial defect risk; gap adjustment may still be needed.
• Boine customer support available for troubleshooting and compatibility confirmation.

Who is this for: Owners, landscapers, and maintenance technicians who service Kawasaki FH-series small engines and want a direct-fit, value-minded ignition coil replacement. This 2-pack is particularly useful for those keeping several machines in service or who prefer replacing coils in pairs to ensure consistent ignition across equipment.
