Description

When your older tractor starts running rough or losing power, there’s a good chance worn spark plugs are the culprit. These Autolite 216 spark plugs are designed to fire up gas engines in vintage tractors and smaller equipment that still use the classic 14mm thread design. They’re built to deliver consistent ignition and keep your machine running like it should.

What You’re Getting

Medium heat range design works well in most operating conditions without fouling or overheating
Standard tip configuration provides reliable spark without fancy electronics or special wiring
Non-resistor design is perfect for older tractors that don’t need interference suppression
Four-pack gives you spares or covers a complete tune-up for multi-cylinder engines

Built for Real Farm Work

These plugs feature 14mm thread diameter with 7/16″ reach and 13/16″ hex, which makes them a direct fit for many older Ford, Massey Ferguson, International, and other vintage tractor engines. Whether you’re running a utility tractor for chores around the farm or firing up that old workhorse for harvest season, these plugs deliver the spark you need.

Made to Last

Autolite has been making spark plugs for decades, and they know what it takes to handle farm conditions. The medium heat range means these plugs won’t foul out from light-duty work but can still handle sustained operation without overheating. They’re built to fire consistently through dust, temperature swings, and long hours in the field.

Good to Know

Installation is straightforward with the standard 13/16″ hex—just use a spark plug socket and don’t overtighten. Gap these plugs to your engine’s specification before installing, and it’s always smart to replace them as a set to keep your engine running smooth. Having extras on hand means you’re ready for routine maintenance or that unexpected misfire.
