Description

When your International Harvester tractor starts losing power, running rough, or won’t idle smoothly, worn intake valves are often the culprit. These valves control the air and fuel mixture flowing into your engine’s cylinders, and when they’re not sealing properly, you’ll feel it in the field. This replacement intake valve gets your engine breathing like it should again.

What You’re Getting

Precision-machined valve that meets OEM specifications for proper seating and seal
Hardened steel construction that stands up to the high heat and pressure of engine operation
Proper stem diameter and length for smooth operation in your valve guides
Six valves included since your International engine uses six intake valves total

Built for Real Farm Work

These intake valves are designed for the reliable International Harvester engines that power everything from utility tractors to larger field machines. Whether you’re running a hay operation, working cattle, or handling general farm duties, your International’s engine depends on these valves opening and closing thousands of times per minute to keep you moving.

Made to Last

TISCO builds these valves to handle the demanding conditions inside your engine. The valve face is precision-ground for a tight seal against the valve seat, while the hardened stem resists wear from constant contact with the valve guides and rocker arms. These are built to give you the same service life as the original equipment.

Good to Know

Valve replacement requires some engine disassembly, so it’s often done as part of a larger engine overhaul. If you’re doing one valve, it’s smart to check the others while you’re in there. Make sure your valve guides are in good shape too – worn guides will eat up new valves pretty quickly.
