QINLANAP Ignition Coil Kit for Kawasaki FH721V FH601V FH641V FH661V FH680V — 2-Pack with Starter Solenoid & 2 Spark Plugs

QINLANAP 2-pack ignition coil module kit replaces worn coils and includes a starter solenoid relay plus spark plugs to restore spark and starting reliability on compatible Kawasaki lawn mower engines.

If your Kawasaki-powered mower struggles to start, misfires, or runs unevenly, this replacement kit provides the core ignition components needed for many small-engine tune-ups. Designed to fit FH721V, FH601V, FH641V, FH661V and FH680V engines, the set swaps in quickly for original parts numbered 21171-0742, 21171-0713, 21171-7039 and 21171-0745. Packaged with two ignition coil modules, a starter solenoid relay and two spark plugs, it supplies both the coils and a basic starting circuit part so you can address common ignition failures in one purchase.

How will replacing the ignition coils affect mower starting and performance?

Fresh ignition coils deliver a more consistent high-voltage pulse to the spark plug, improving ignition timing and combustion stability. After install you should notice easier cold starts, fewer stalls, and steadier idling if the coils were the root cause.

• Replaces failing OEM coils for compatible Kawasaki engine models
• Provides two coil modules to service both cylinders where applicable
• Reduces misfires and rough running caused by weak coils
• Includes spark plugs to complete the ignition circuit refresh

Is this kit easy to install for a homeowner mechanic?

The components are direct-fit replacements that follow the same mounting points and wire connections as original parts, so a person with basic hand tools and mechanical aptitude can complete the swap. Remove the old coil(s), transfer any required brackets or heat shields, connect plug wires and the ignition lead, then secure the new coil modules and test starting.

• Direct-fit for FH721V, FH601V, FH641V, FH661V, FH680V engines
• Basic hand tools and common mechanical skills required
• Includes starter solenoid relay to address starting circuit issues
• Manufacturer offers support if you encounter installation questions

What exactly comes in the package and which part numbers does it replace?

The kit contains two ignition coil modules, a starter solenoid relay and two spark plugs so you can refresh the entire ignition pathway on compatible engines. It is intended as a replacement for Kawasaki part numbers 21171-0742, 21171-0713, 21171-7039 and 21171-0745, matching the same functional role in the engine’s ignition system.

• 2 x ignition coil modules (matches OEM mounting and wiring)
• 1 x starter solenoid relay to support reliable starter engagement
• 2 x spark plugs included for immediate install and testing
• Cross-replaces listed Kawasaki part numbers for easier sourcing

How long will these replacement parts last and is there coverage?

Longevity depends on operation conditions and maintenance, but replacing aged or damaged coils and plugs typically restores normal service life expectations for the ignition system. QINLANAP offers a 365-day guarantee after purchase to cover defects and installation issues arising from manufacturing problems.

• Durability varies with heat, vibration and exposure to elements
• Includes one-year guarantee for manufacturing defects
• Routine inspections and spark plug gaps maintain optimal life
• Contact QINLANAP support for warranty or installation help

Who is this for: This kit is aimed at homeowners, landscapers and small-engine technicians who own or service Kawasaki lawn mowers with FH601V–FH721V series engines and need a straightforward ignition repair. It’s useful when original coils, plugs or the starter solenoid relay show signs of failure — offering a cost-effective way to restore starting reliability without replacing the entire engine. If you prefer OEM-equivalent parts that arrive ready to install with minimal extra purchases, this multi-piece kit is designed to meet that need.
