Description
When you’re running a commercial truck or bus day after day, engine longevity depends on keeping the dust, road grime, and debris out of the intake system. A clogged or damaged air filter doesn’t just hurt performance—it can turn expensive diesel engines into costly rebuilds faster than you’d think. This Baldwin air filter catches all that road dirt before it can reach your engine’s internals, keeping you rolling when downtime isn’t an option.
Key Features
- Large 12 3/8-inch length and 10 3/8-inch diameter capture high volumes of contaminants without restricting airflow
- Quality pleated media handles the constant vibration and temperature swings of commercial operation
- Direct replacement design fits International Harvester buses and trucks without modifications
- Robust construction stands up to the punishment of daily commercial use
Built for Commercial Work
This filter is engineered for International Harvester buses and trucks that put in serious miles under demanding conditions. Whether you’re running a school bus route, hauling freight across the country, or operating municipal vehicles, these machines work in environments where clean air filtration makes the difference between reliable operation and expensive breakdowns.
Made to Last
Baldwin has been making filters for commercial vehicles for decades, and they understand what heavy-duty operation demands. The quality filter media and sturdy construction handle the constant airflow demands and harsh conditions that commercial engines face every day, protecting your investment in expensive engine components.
Installation Notes
This is a direct replacement that installs with basic tools in minutes. Always inspect your air cleaner housing for cracks or damaged seals while you’ve got the old filter out—any air leak here bypasses your filtration system. Keep a spare filter on hand, especially if you’re running high-mileage routes or operating in dusty conditions.
