Panari Ignition Coil for Generac GP Series & Honda GX Engines — GP5500 Fit, Includes Spark Plug, Direct-Fit Replacement

Panari GP5500 Ignition Coil: a direct-fit replacement ignition coil and spark plug kit engineered to restore spark and reliable starts on Generac GP series and compatible Honda GX engines.

If your portable generator stalls, cranks but won’t fire, or shows intermittent spark, the ignition coil is a common wear item. This Panari assembly is designed to work with a broad set of models — including Generac GP5000 through GP8000E units and Honda GX-series small engines — and ships with a matching spark plug so you have what’s needed to get the engine running again.

Which generator and engine models does this Panari coil fit?

The coil is built to match electrical and mounting dimensions found on many Generac GP series portable generators and several Honda GX family engines. It replaces common OEM numbers and fits engines from roughly 8–13 HP and generator outputs from about 5 kW to 6.5 kW.

• Generac models: GP5000, GP5500, GP6000E, GP6500, GP6500E, GP7500, GP7500E, GP8000E and XT8000E variants
• Other compatible units: H5500, H6500, H7500, HW and RS series listed in product details
• Honda GX family compatibility: GX240, GX270, GX340, GX390 and GX350-equivalent engines
• Replaces OEM part numbers like 30500-ZF6-W01 through related variants

How will installing this ignition coil affect engine starting?

Replacing a failing coil restores the high-voltage pulse sent to the spark plug, which is essential for reliable ignition of the air/fuel charge. After correct installation and using the included spark plug, most units that previously cranked but did not fire will start normally.

• Delivers the high-voltage spark required for combustion
• Reduces misfires and hard-start conditions when installed properly
• Includes a spark plug to simplify swap-out and ensure compatibility

What comes in the box and what should I check before installing?

The kit contains the ignition coil assembly and a replacement spark plug so you can complete the basic ignition service in one visit. Before fitting, confirm mounting hole spacing, connector type, and gap the supplied spark plug to your engine manufacturer’s specification.

• 1 x Panari ignition coil assembly
• 1 x compatible spark plug included
• Verify coil mounting, flywheel clearance, and plug gap before first start

Is this a direct OEM replacement or an aftermarket alternative?

Panari supplies an aftermarket replacement designed to meet the same fit and functional needs as several OEM coils. It uses compatible electrical output and mounting geometry to match common Generac and Honda small engine applications.

• Manufactured as a replacement part compatible with listed OEM numbers
• Intended to match OEM spark energy and physical fitment
• Sold as a unit with plug for straightforward installation

Who is this for: The Panari GP5500 ignition coil kit is for DIY mechanics, small-engine technicians, fleet managers, and generator owners who need a reliable, off-the-shelf ignition replacement for Generac GP-series portable generators or compatible Honda GX engines. Choose this kit when the engine cranks but won’t fire, spark is weak or inconsistent, or when replacing a visibly damaged or corroded coil.
