How does this replacement ignition coil improve starting and run quality?

Replacing an old or failed magneto armature restores the spark energy delivered to the spark plug, which helps ensure consistent ignition and smoother running. Proper fit and correct wiring alignment reduce misfires and weak starts when installed correctly.

• Delivers consistent secondary voltage to the spark plug for reliable ignition.
• Designed with OEM-style mounting and lead configuration for correct alignment.
• Includes two spark plugs matched to the coils to simplify replacement.
• Sold as a pair to service dual-coil or multi-engine maintenance tasks.

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

The package contains two ALRACALL ignition coils and two replacement spark plugs that correspond to RCJ8Y specifications. There is no printed manual included, so inspect parts and compare them to your old coils before beginning the swap.

• Package contents: 2 ignition coils and 2 spark plugs (no instructions).
• Verify coil mounting tabs, terminal spacing, and lead lengths against the old coil.
• Confirm spark plug thread size and heat range match your engine (replaces RCJ8Y).
• Disconnect battery or ignition source and follow safe engine repair practices during installation.

Will these coils work on my John Deere or Cub Cadet mower?

Yes, the kit lists cross-reference part numbers used by John Deere (AM133525 and related PNs) and common Cub Cadet/MTD models. Compatibility depends on the exact engine or chassis part number, so match your machine’s OEM references before purchase.
