When you’re working on vintage tractors or older engines, finding the right spark plug can make all the difference between a smooth-running engine and one that sputters and misfires. This Autolite 3076 features a cold heat range with 7/8″-18 thread diameter, 5/8″ reach, and 15/16″ hex, making it perfect for older engines that need reliable ignition without the modern complications.
What You’re Getting
- Cold heat range design that’s ideal for engines running under heavy loads or high compression
- Large 7/8″-18 thread diameter that fits those big, robust engine blocks from yesteryear
- Standard tip, non-resistor design that works with older ignition systems without interference
- Direct replacement for multiple Champion plugs—one part covers several applications
Built for Real Farm Work
This plug is designed for vintage tractors and older agricultural engines that used the larger thread diameter. Whether you’re restoring a classic Farmall, Ford N-series, or other heritage tractors, this cold heat range plug handles the demands of hard work without overheating or fouling out when you’re running at full throttle.
Made to Last
The cold heat range means this plug dissipates heat quickly, which is exactly what you want in engines that work hard all day. The non-resistor design ensures strong spark delivery to older ignition systems that weren’t built with electronic interference concerns in mind.
Good to Know
This plug crosses with Champion W10, W14, C16C, W18, and W20, so if you’ve been using any of those numbers, this Autolite will drop right in. The 15/16″ hex makes it easy to install with standard tools, and the cold heat range means you won’t have to worry about pre-ignition or overheating during those long days in the field.
