YAMAKATO ignition coil kit for Briggs & Stratton V-Twin — 2-pack with air-gap gauge, direct replacement

YAMAKATO ignition coil kit replaces worn coils on many Briggs & Stratton V-Twin lawnmower engines to restore spark and keep the motor running reliably.

This aftermarket kit includes two replacement ignition coils plus an air-gap gauge designed to fit a wide range of Briggs & Stratton Intek V-Twin models (fits numbers like 592846, 799651, 473177, 691060, 401577 and compatible replacements such as 845126 and 843327). It’s intended for owners who need a direct coil swap to regain consistent ignition performance. Before ordering, confirm the original part number and the coil’s physical size to ensure compatibility.

How do I know this coil fits my Briggs & Stratton engine?

Match the old coil part number printed on your current unit with the list of compatible numbers above and compare the mounting holes and lead routing to your engine. If the coil casing or kill-wire connector interferes with surrounding fins, minor trimming of the cylinder-head fins may be required for a correct fit.

• Compatible with listed part numbers: 592846, 799651, 473177, 691060, 401577.
• Also replaces some 845126, 843327, 843860, 592376 units.
• Verify physical dimensions and mounting hole pattern before installation.

What comes in the package and what tools do I need?

The kit ships with two ignition coils and one air-gap gauge so you can set the correct gap during installation. Basic hand tools—socket set, screwdrivers, and a feeler gauge or the included air-gap tool—are typically all that’s needed.

• Includes: 2 x ignition coils, 1 x air-gap gauge.
• Tools: ratchet, sockets, screwdriver, feeler gauge (or supplied gauge).
• Allow time to verify wiring and gap before full reassembly.

Will I need to modify my engine to install these coils?

Most installations are direct swaps, but on some engines the coil’s casing can contact the kill-wire connector or cylinder-head fins. If that occurs, gently filing a small amount of fin material usually clears the interference without affecting engine function.

• Minor fin trimming may be necessary for a flush fit.
• Ensure kill-wire clearance to avoid accidental grounding.
• Follow safe engine-disassembly practices and disconnect the spark plug wire first.

Are these coils OEM parts or aftermarket replacements?

These are aftermarket YAMAKATO coils manufactured to match the electrical and mounting characteristics of the listed Briggs & Stratton originals. They are suitable for repair and maintenance, but check manufacturer guidance for warranty or CARB certification questions before use.

• Aftermarket alternative to OEM Briggs & Stratton coils.
• Designed to replicate original fit and spark characteristics.
• Confirm warranty and regulatory requirements prior to purchase.

Who this is for: This coil kit is intended for homeowners, landscapers, and small-engine technicians who need a cost-effective replacement for failing ignition coils on Briggs & Stratton Intek V-Twin lawnmowers.
