PARTSRUN Ignition Coil Module 2-Pack for Briggs & Stratton 18–22HP Engines — Direct-Fit Replace 592846/691060

These two PARTSRUN ignition coil modules replace part numbers 592846, 691060 and 799651 to restore spark on compatible Briggs & Stratton and John Deere 18–22HP engines.

If your mower stalls, won’t start, or runs erratically, a failing ignition coil is often the cause. PARTSRUN’s 2-pack coil set is designed as a direct-fit replacement for common OEM numbers including John Deere MIA12346 and LG691060, and fits many Z-Trak and lawn tractor models. The pair gives you a spare for the future or a matched replacement for multi-engine maintenance.

Will these coils fit my Briggs & Stratton or John Deere engine?

These coils are intended for 18–22HP single-cylinder engines that use the 592846/691060/799651 family of ignition modules. Check the engine model and OEM number before ordering to ensure compatibility. Vehicle fitment lists and part cross-references from your owner’s manual will confirm suitability.

• Replaces OEM numbers: 592846, 691060, 799651, MIA12346, LG691060
• Commonly used on John Deere Z445, Z465, Z625 Z-Trak models and similar
• Designed for 18–22HP Briggs & Stratton engines
• Sold as a two-piece set for matched replacements or backup

How do these ignition coils affect starting and engine performance?

A fresh coil delivers a strong, consistent spark which improves cold starts and reduces misfires. Replacing a weak or intermittent coil can stop hard-starting issues and smooth out low-RPM operation. Properly installed coils help restore original engine responsiveness without altering fuel systems or mechanical timing.

• Re-establishes reliable spark for better ignition
• Reduces stalling and rough idle caused by coil failure
• No engine tuning required—direct electrical/mechanical swap
• Two coils let you replace both the faulty unit and keep a spare

What should I know about installation and durability?

Installation is straightforward with basic hand tools: disconnect the spark plug and lead, remove the old coil, and mount the new unit using the existing hardware and wiring. Keep fasteners torqued to factory specs and ensure proper air gap where applicable. These coils are manufactured to meet common engine electrical requirements, but environmental exposure and improper mounting can shorten life.

• Uses original mounting points—no case modification required
• Follow manufacturer torque and air-gap recommendations
• Inspect wiring and connectors; replace cracked boots or brittle wires
• Sold as a 2-pack for convenience and redundancy

How can I diagnose a bad coil before buying?

Typical signs of a failing ignition coil include a weak or absent spark, engine sputtering under load, or a lawn tractor that starts only intermittently. You can verify by checking for spark with a proper tester, measuring primary/secondary resistance, or swapping with a known-good coil if available. Always follow safety precautions when testing ignition components.

• Look for inconsistent starting or sudden stalling
• Test for visible spark using a spark tester—do not use bare hands
• Measure coil resistance against manufacturer specifications
• Replace with the PARTSRUN 2-pack for matched performance if faulty

Who is this for: Lawn care professionals, weekend maintainers, and small-engine repair shops who service John Deere Z-Trak mowers and other vehicles with 18–22HP Briggs & Stratton engines. Choose this PARTSRUN 2-pack if you want OEM cross-referenced parts that simplify repairs, provide a spare for future maintenance, and aim to restore reliable ignition without sourcing multiple part numbers.
