Description

If your tractor or other farm equipment is hard to start on cold mornings or seems to lack the power it used to have, worn spark plugs are often the culprit. These medium hot spark plugs with their standard tip design are engineered for agricultural engines that work hard and run long. With an 18mm thread diameter, 1/2″ reach, and 7/8″ hex, they’re built to handle the demands of farm work.

What You’re Getting

Four high-quality TISCO spark plugs that deliver reliable ignition in all conditions
Medium heat range that prevents fouling during low-RPM operation while handling high loads
Standard tip design that provides dependable spark formation without the complexity of specialty electrodes
7/8″ hex that makes installation and removal straightforward with standard tools
Durable construction that stands up to the vibration and temperature extremes of farm equipment

Built for Real Farm Work

These plugs fit a wide range of agricultural equipment including older tractors, generators, pumps, and other gas-powered farm machinery. They’re especially well-suited for equipment that operates at varying loads and speeds – like tractors that might be idling around the barn one minute and pulling a heavy implement through the field the next.

Made to Last

The TISCO brand builds these plugs to handle the harsh conditions of farm equipment. They resist fouling from carbon buildup and maintain their gap longer than standard automotive plugs, which means fewer trips to town for replacements and less downtime during busy seasons.

Good to Know

The 4-pack gives you enough plugs for a complete engine refresh or spares for the shop. Gap them to your engine manufacturer’s specifications before installation, and don’t over-tighten – the gasket seal does the work, not torque. Keep a spare set on hand because there’s never a good time for ignition problems when there’s work to do.
