Description

When your small engine starts running rough, hard starting, or just doesn’t sound right, a fresh spark plug often does the trick. This medium-hot spark plug is designed for smaller engines that need reliable ignition without the complexity of automotive plugs. Whether it’s cutting season or harvest time, you need your equipment firing on all cylinders.

What You’re Getting

  • Medium-hot heat range that works well in most small air-cooled engines
  • 14mm thread diameter with 3/4-inch reach fits a wide variety of applications
  • 13/16-inch hex makes removal and installation simple with standard tools
  • Quality construction that provides consistent spark and long service life

Built for Real Farm Work

This plug works great in small engines you’ll find around the farm—mowers, generators, pressure washers, and other air-cooled equipment. The medium heat range handles the temperature swings these engines see during normal operation, from cold morning starts to full-throttle work in summer heat.

Made to Last

Small engines work hard and this plug is built to keep up. The electrode design provides reliable ignition while resisting fouling from occasional rich running or stop-and-go operation that’s common with outdoor power equipment.

Installation Notes

Thread the plug in by hand first to avoid cross-threading, then snug it down with a spark plug wrench. Don’t over-tighten—the gasket seat just needs to compress fully to seal properly. Gap is pre-set from the factory, so you’re ready to go right out of the box.
