Description
When your International Harvester tractor starts losing power or running rough, worn intake valves might be the culprit. These valves control the air-fuel mixture entering each cylinder, and when they’re not sealing properly, you’ll notice it right away in your engine’s performance. A fresh set of intake valves brings back that smooth idle and strong pull you’re used to.
What You’re Getting
- Proper valve timing and sealing for optimal engine compression and performance
- TISCO quality construction that matches OEM specifications for reliable operation
- Precise dimensions engineered to work with your IH engine’s valve guides and seats
- Set of four valves—exactly what you need for a complete intake valve replacement
Built for Real Farm Work
This intake valve fits International Harvester 100 series, 200 Series, Super A-1 Series (prior to S/N 310300), Super AV-1 Series (prior to S/N 310300), and Super C Series tractors. These are the utility and row-crop tractors with 4-cylinder gas engines and 123 CID displacement that have been the backbone of farms for decades.
Made to Last
Farm engines work hard in dusty conditions with temperature swings that would kill a car engine. These intake valves are built to handle that punishment, with proper metallurgy and heat treatment to resist warping and wear. When installed correctly with proper valve seat work, they’ll give you years of reliable service.
Good to Know
Intake valve replacement is a job for someone comfortable with engine work—you’ll need to remove the head and have the valve seats checked or recut. These valves have a 4-57/64 inch length, so make sure your measurements match before ordering. While you’re in there, it’s smart to check the valve guides and consider replacing the exhaust valves at the same time.
