Description

When your tractor starts acting up – rough idling, hard starting, or just not running as smooth as it should – worn spark plugs are often the culprit. This reliable medium-hot spark plug delivers the consistent ignition your engine needs to fire properly every time. It’s built to the same specs as the original equipment, so you know it’ll do the job right.

What You’re Getting

Medium-hot heat range that works well in most operating conditions without fouling
18mm thread diameter with 1/2 inch reach for proper fit in your cylinder head
Standard tip design provides reliable spark across the gap
7/8 inch hex makes installation and removal straightforward with standard tools
Durable construction that handles the heat and pressure of hard-working engines

Built for Real Farm Work

This plug fits a wide range of vintage and classic tractor engines that use the 18mm thread size. Whether you’re working on an older utility tractor, a classic row-crop machine, or restoring a piece of farm history, this plug delivers dependable performance when you need it most.

Made to Last

Farm engines run hard and long, and these plugs are built to keep up. The medium-hot heat range prevents fouling during normal operation while still burning off deposits during harder work. Quality construction means consistent performance season after season.

Good to Know

Always gap your plugs to your engine’s specification before installing – don’t assume they come pre-gapped correctly. A quick tip: remove one plug at a time if you’re doing a full set, so you don’t mix up the firing order on the plug wires. Clean the threads in the cylinder head while you’ve got the old plugs out.
