Description

When your small engine starts hard or misfires under load, it’s often the spark plug letting you down. This medium heat spark plug delivers reliable ignition for all kinds of farm equipment—from generators to pressure washers to compact tractors. With the right heat range and solid construction, it’ll fire consistently whether you’re starting cold or running hard.

What You’re Getting

Medium heat range that works well in most small engine applications
14mm thread diameter with 3/4″ reach fits a wide range of engines
13/16″ hex makes installation easy with standard tools
Quality construction that stands up to regular use and temperature swings

Built for Real Farm Work

This plug works in all kinds of small engines you’ll find around the farm—portable generators, pressure washers, log splitters, and compact utility tractors. It’s designed for the medium heat range that most air-cooled engines need to run clean and efficient.

Made to Last

Farm equipment doesn’t get babied, and this spark plug is built to handle real-world conditions. The electrode and insulator are designed to resist fouling from occasional rich running or dusty conditions that come with outdoor work.

Good to Know

This is a direct replacement for Champion J8, J8C, and UJ8 plugs, so you can swap it right in. Gap it to your engine manufacturer’s specs before installation. If you’re replacing multiple plugs, it’s always smart to change them all at the same time for consistent performance.
