High-performance ignition coils from IGCLINIC designed to replace worn units on Briggs & Stratton 18–22HP Intek V-Twin engines — sold as a two-piece set for quick swap-out.

If your mower or outdoor power equipment is running rough, misfiring, or refusing to start, the ignition coil is often the culprit. These IGCLINIC coils are built to match the electrical and mechanical fit of popular Briggs & Stratton Intek V-Twin models, fitting a wide range of part numbers so you can restore reliable spark and smoother engine operation without buying a whole new engine control module.

Will these coils fit my Briggs & Stratton 401000, 405000, or 407000 engine?

These coils are manufactured to be compatible with the 401000, 405000, and 407000 series Intek V-Twin engines in the 18–22HP range. They are intended as direct replacements for many OEM part numbers—but you should compare the appearance and mounting points against your original coil before installing.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone familiar with routine small-engine maintenance. Basic hand tools—socket set, screwdrivers, and possibly a feeler gauge—are typically sufficient; no specialized equipment is required. Always disconnect the spark plug wires and battery (if fitted) before servicing to avoid shock or accidental starts.
