Description
If your Ford 8N has been hard to start or running rough, worn spark plug wires might be the culprit. Old wires can develop cracks that let moisture in and spark energy out, leading to weak ignition and poor performance. This complete wire set gets your N-series tractor firing on all cylinders again, just like it did when it rolled off the assembly line.
What You’re Getting
- Complete 4-cylinder wire set custom-made for your 8N’s side-mount distributor setup
- Pre-assembled and ready to install—no cutting or crimping required
- High-quality insulation that resists cracking from heat and weather
- Proper wire core for reliable spark delivery to all four cylinders
Built for Real Farm Work
This wire set is specifically designed for Ford 4-cylinder tractors built from 1950 to 1952, particularly the 8N models equipped with the side-mount distributor. These tractors were workhorses in their day, handling everything from plowing and cultivating to belt work and hauling. Having a strong, consistent spark is crucial for reliable starting and smooth operation under load.
Made to Last
TISCO builds these wire sets to handle the vibration and temperature swings that come with tractor work. The insulation stays flexible in cold weather and won’t crack under the hood heat, while the connections are built to maintain solid contact with your distributor cap and spark plugs season after season.
Installation Notes
This is a direct replacement for your original wire set—no modifications needed. When installing, route the wires away from hot exhaust components and make sure they’re seated firmly in the distributor cap. A little dielectric grease on the spark plug connections helps prevent corrosion and makes future removal easier.
