Boine Ignition Coil Replacement Kit for Kawasaki FH-Series — 2-Piece Pre-tested Direct-Fit

These two Boine ignition coils are drop-in replacements engineered to restore reliable spark and efficient combustion for a range of Kawasaki FH381V–FH721D engines.

Designed as a straightforward aftermarket swap for worn or faulty ignition coils, this 2-piece kit fits multiple Kawasaki FH-series engines and replaces several OEM part numbers. Each coil is pre-tested at the factory for fit and basic performance so you can install it without extra adjustments. The unit is intended to improve ignition response and maintain steady spark delivery under normal operating conditions.

Will this coil fit my Kawasaki engine model?

Yes — the kit is compatible with many Kawasaki FH-series overhead-valve engines. Check your engine’s model code against the list below and cross-reference any OEM part number you currently have.

• Compatible models: FH381V, FH430V, FH480V, FH500V, FH531, FH541V, FH580V, FH601V, FH641V, FH680V, FH721V, FH601D, FH641D, FH680D, FH721D.
• Replaces these part numbers: 21171-7001, 21171-7003, 21171-7006, 21171-7007, 21171-7013, 21171-7018, 21171-7022, 21171-7024, 21171-7026, 21171-7037.
• Confirm compatibility by matching engine model or existing coil part number before purchase.

How difficult is installation and what tools are required?

Installation is intended to be simple for anyone comfortable with basic small-engine maintenance. Coils arrive pre-tested and sized to the original mounting points, so installers typically only need common hand tools and a moment to set gap and wiring.

• Typical tools: socket set, screwdriver, feeler gauge for air gap checking.
• Steps: disconnect spark plug lead, remove old coil, transfer mounting hardware, set the specified air gap, reconnect wires.
• No special programming or ECU work required — direct physical replacement.

What performance or reliability changes should I expect?

Replacing a worn coil with this Boine unit helps reestablish consistent spark timing and can make starting and throttle response more predictable. It’s built to meet or closely match the original coil’s electrical characteristics for steady performance under normal conditions.

• Improves combustion consistency when the original coil is degrading.
• Faster reaction to ignition demand compared with a failing or weak coil.
• Designed for routine engine conditions; not a high-performance racing component.

Who this is for: This Boine 2-piece ignition coil set is suited for homeowners, landscapers, and small-engine technicians who need an affordable, factory-tested replacement for Kawasaki FH-series engines. Choose this kit if you need a direct-fit coil that replaces common OEM numbers, want straightforward installation without added tuning, and seek dependable spark performance for everyday mowing and light commercial use.
