Caltric ignition coils — a 2-piece replacement set built with copper-wound coils to restore spark and reliable starting for compatible John Deere lawn tractors and utility vehicles.

These replacement ignition coils are aftermarket components designed to match the electrical and mechanical fit of OEM references AM120732, AM105571, and AM118703. Sold as a pair, the coils use copper windings and robust housings intended to deliver consistent ignition performance for a range of John Deere models. Before purchasing, compare the OEM numbers and mounting points in your equipment to the images and specifications to confirm compatibility.

Will these coils fit my John Deere model?

They are manufactured to correspond to the listed OEM numbers and many common John Deere lawn and utility machines. Fitment depends on engine and mounting style, so visual and part-number confirmation is recommended.

• OEM references included: AM120732, AM105571, AM118703
• Common compatible machines: Lawn & Garden Tractors 320, 345, 425, GX345

How do these ignition coils affect engine starting and running?

Ignition coils transform low-voltage into the high-voltage spark the spark plug needs. Replacing worn or damaged coils can improve starting reliability and reduce misfires, but should be paired with good plugs and proper timing for best results.

• Provides high-voltage output via copper windings for consistent spark
• Helps restore reliable ignition if original coil is faulty
• Sold as a 2x coil set to service dual-coil systems or keep a spare

What are the physical and electrical features of these parts?

These replacement coils use copper wire windings and are built to match the electrical characteristics of the referenced OEM parts. Mounting flange, terminal layout, and connector shape are designed to mimic factory components, but always verify against your existing unit.

• Material: copper wire winding for reliable conductivity
• Includes two coils per order for immediate installation or backup
• Connector and mounting dimensions intended to match OEM form factor

Any installation tips or fitment checks I should follow?

Turn off the engine and disconnect the battery before replacing coils to avoid shocks and accidental starts. Compare the coil’s mounting holes, stud positions, and electrical terminals to your original part, and replace spark plugs or wires if they show wear.

• Disconnect battery and ground the ignition before working
• Match OEM numbers and photograph original coil orientation before removal
• Use dielectric grease on terminals and check plug gap after installation
