MOTO1988 Ignition Coil Kit for Honda TRX420 Rancher 2007–2013 — Direct-Fit with Spark Plug Included

MOTO1988 Ignition Coil & Spark Plug with Cap is a direct-fit replacement kit for Honda TRX420/Rancher ATVs from 2007–2013, providing a ready-to-install ignition assembly and spark plug to restore reliable spark delivery.

If your Rancher/TRX420 is showing hard starts, intermittent misfires, or reduced throttle response, a failing ignition coil or worn spark plug assembly is often the cause. This MOTO1988 kit includes a pre-assembled ignition coil with cap and a matched spark plug designed to meet the OEM form, fit and function for Honda part numbers 30510-HP5-601 and 30700-MBN-671. Each component is inspected before shipping and intended for direct installation on specified TRX420 model years.

How will this kit affect starting and throttle response?

Replacing a weak coil or fouled plug restores the spark strength needed for consistent combustion. Expect quicker starts, fewer stalls at idle, and smoother acceleration once the new coil and plug deliver consistent high-voltage sparks to the cylinder.

• Restores correct spark timing and energy for reliable ignition.
• Helps eliminate intermittent misfires and rough idling.
• Direct-replacement design avoids electrical or mechanical fit issues.

Will this fit my Honda TRX420 or Rancher model?

This assembly is built to match the OEM specifications for multiple TRX420 model variants from 2007 through 2013. Verify your machine's model code and compare the OEM number 30510-HP5-601 or the spark plug number 30700-MBN-671 if you need confirmation.

• Compatible with TRX420 FPA, FPM, FA, FPE (2009–2013).

What quality checks and packaging come with the product?

MOTO1988 inspects every assembly before shipment; materials and connections are quality-controlled to reduce early failure. The kit ships as an OEM-style package containing one ignition coil with cap and one spark plug, ready for installation without modification.

How should I install and maintain the new coil and plug?

Installation is straightforward for anyone familiar with basic ATV maintenance: disconnect the battery, remove the old coil/plug, and refit the new parts in reverse order. After installation, periodically inspect the cap and plug for corrosion, secure connections, and replace the spark plug per normal service intervals.

• Disconnect battery ground before starting work for safety.
• Tighten spark plug to the torque spec in your service manual.
• Inspect rubber boot and wiring periodically for cracks or wear.
