Shunmo Spark Plug Wire Set for John Deere Onan P216-P224, Pair with Molded Terminals

This pair of spark plug wires is designed specifically for a range of John Deere Onan small engines (P216, P218, P220, P224, B43E, B43G) and garden tractors (models 316, 318, 420), and it also fits Ingersoll 4018. The wires include molded terminals that seat over the spark plug to reduce the chance of loosening or detachment during operation. Built from flexible rubber construction, they carry the high-voltage current necessary for ignition systems while remaining lightweight and resistant to sudden fracture under normal use.

Will these wires fit my John Deere or Ingersoll engine?

Compatibility is limited to the listed Onan engine codes and tractor models; confirm the engine code on your unit before ordering. If your engine or tractor model matches any of the P216, P218, P220, P224, B43E, B43G, 316, 318, 420, or Ingersoll 4018 references, these wires are intended to be a direct-fit replacement.

• Fits John Deere Onan: P216, P218, P220, P224, B43E, B43G
• Fits John Deere garden tractors: 316, 318, 420
• Also compatible with: Ingersoll model 4018
• Check your engine code and spark plug layout before purchase

How are these spark plug wires constructed and installed?

The Shunmo wires use a rubber outer jacket for flexibility and durability and include a terminal at the end that locks onto the spark plug to help prevent accidental disconnection. Installation is plug-and-play for compatible engines: remove the old wire, press the terminal over the plug until it seats, and route the wire away from heat and moving parts.

• Rubber construction provides flexibility and impact resistance
• Molded terminal seats on the spark plug for a secure connection
• Easy replacement: remove old lead, push new terminal onto plug, secure routing
• Keep wires clear of exhaust and belts for longevity

What performance differences should I expect after replacing wires?

New ignition wires restore the path for high-voltage current from the coil to the spark plug, which can improve ignition reliability compared with worn or cracked leads. While these wires do not change engine tuning, they help maintain consistent spark delivery when installed correctly and in good condition.

• Restores reliable high-voltage conduction to spark plugs
• Reduces misfires caused by cracked or loose leads
• Helps maintain smooth engine starts and steady idle when paired with functioning ignition components
• Sold as a set of two wires for matched replacement needs

Are there any care tips or limitations I should know?

These wires are durable but not immune to damage from extreme heat, oil, or sharp abrasion. Inspect routing and terminals periodically and replace wires if the jacket cracks or connections become loose. Always verify fit before installation to avoid returns.

• Avoid direct contact with hot exhaust surfaces and moving parts
• Replace if the rubber jacket shows cracking or hardening
• Confirm engine model compatibility before ordering
• Sold as 2 spark plug wires per package

Who is this for: This Shunmo wire set is aimed at owners and mechanics of compatible John Deere garden tractors and equipment using the listed Onan engines, plus users of Ingersoll 4018 machines. It suits anyone needing a straightforward, OEM-style spark plug lead replacement—especially DIY maintainers who want a secure terminal fit and flexible wiring for a reliable ignition connection.
