Description

If your old Farmall’s been missing and sputtering or just won’t start like it used to, worn spark plug wires could be the culprit. Over the years, those original wires take a beating from heat, vibration, and time—causing weak spark or complete misfires. This preassembled wire set gets your classic International Harvester running smooth and strong again.

What You’re Getting

Complete preassembled set—no guesswork on wire lengths or routing
Quality construction that handles the heat and vibration of vintage engines
Proper resistance values to deliver strong, consistent spark
Direct replacement for original factory wires

Built for Real Farm Work

This wire set covers the full range of classic International Harvester tractors from the little Cub and Cub Lo-Boy utility tractors up through the bigger M and MTA models. Whether you’re running a Cub for chores around the homestead or putting a Super M to work in the fields, these are the workhorses that helped build American agriculture.

Made to Last

TISCO builds these wire sets to handle the demands of vintage tractor engines. The insulation resists cracking from engine heat and the connectors stay tight even with the vibration these old engines produce. You’ll get reliable ignition season after season.

Good to Know

Installation is straightforward—just remove the old wires one at a time and replace with the new ones to keep the firing order correct. The preassembled set takes the guesswork out of getting the right lengths. If you’re doing a full tune-up, this is the perfect time to check your points, condenser, and plugs while you’re at it.
