TGGKKPARTS Spark Plug Wire Kit for John Deere 825i & 825i S4 | Copper Core 3pc MIA11722-24

Elevate ignition reliability with a purpose-built wire kit

The TGGKKPARTS Spark Plug Wire Kit is designed for John Deere 825i and 825i S4 models. This copper-core, three-wire set is tailored to the engine’s cylinder layout, with 13.5 inches for Cylinder 1, 10 inches for Cylinder 2, and 8 inches for Cylinder 3. The result is a clean, direct path for spark delivery across all ignition cycles, enabling a smoother start and stable running in varied conditions.

Design and materials that stand up to the elements

High-quality copper conductors are paired with a heavy-duty silicone sleeve. The silicone outer layer shields the winding core from heat, moisture, and chemicals, helping the wires resist environmental stresses found in field and shop settings. The combination is chosen for temperature tolerance and corrosion resistance, which can contribute to a longer service life and more consistent electrical performance over time.

Real-world use and potential benefits

In practical use, fresh ignition wires can support reliable spark delivery and more consistent engine response under demanding tasks or hot, humid conditions. This kit provides a straightforward upgrade path for owners who want to refresh the ignition system without replacing other components, keeping maintenance focused and efficient.

• Fits John Deere 825i and 825i S4 engines with cylinder-specific lengths: 13.5", 10", and 8".
• Copper core aims to maintain solid signal integrity and energy transfer to spark plugs.
• Heavy-duty silicone sleeve protects the winding core from heat, moisture, and chemicals.
• Materials are chosen for high-temperature tolerance and corrosion resistance for longer potential life.
