Description
When your small tractor or utility equipment starts running rough or won’t fire up like it used to, the spark plugs are often the culprit. This medium heat range plug delivers the reliable ignition you need to keep your gas engine running smooth, whether you’re mowing, tilling, or running a generator.
What You’re Getting
- Medium heat range design that handles varying loads without fouling or overheating
- 14mm thread diameter with 3/8 inch reach fits many small tractor and utility engines
- 13/16 inch hex makes removal and installation easy with standard tools
- Standard tip construction provides consistent spark in all weather conditions
Built for Real Farm Work
This spark plug is sized for the smaller gas engines you’ll find on compact tractors, garden tractors, and utility equipment around the farm. Whether you’re running a Bush Hog, operating a generator during harvest, or keeping that old Ford 8N firing on all cylinders, this plug delivers the spark your engine needs.
Made to Last
Farm engines work hard in dusty, dirty conditions, and this plug is built to handle it. The medium heat range means it burns off deposits during normal operation while staying cool enough to prevent pre-ignition when you’re working the engine hard.
Good to Know
Check your owner’s manual for the correct gap specification—most small tractor engines run best with a 0.025 to 0.030 inch gap. When installing, thread in by hand first to avoid cross-threading, then snug down with a socket wrench. Don’t over-tighten—these smaller plugs don’t need as much torque as the big diesel glow plugs.
