Description
A properly sealed air cleaner cap might seem like a small detail, but it’s what keeps dirt and moisture from sneaking into your engine through the air intake system. If you’ve noticed dust building up where it shouldn’t be or your air filter getting dirty faster than usual, a worn or missing cap could be the culprit. This little cap sits inside the intake pipe and does a big job protecting your engine from whatever the field throws at it.

Built for Real Farm Work
These vintage International Harvester tractors were the backbone of American farming for decades. Whether you’re running a compact Cub for yard work and light cultivation or putting a Super A to work with implements, these machines still earn their keep on farms today. This cap fits the classic air cleaner systems that kept these engines running clean through countless hours of dusty field work.
Made to Last
Farm equipment parts need to handle temperature swings, dust, rain, and the constant vibration that comes with the territory. This cap is built to maintain a proper seal while allowing the right amount of airflow to your engine. The sturdy construction ensures it won’t crack or warp, even after years of exposure to the elements.
Installation Notes
Installation is straightforward—the cap fits inside the air intake pipe and should seat firmly in place. Make sure the pipe is clean before installing the new cap for the best seal. If you’re working on one of these vintage machines, it’s a good time to check the entire air cleaner system for any other worn components that might need attention.
