When you’re hauling loads cross-country or making deliveries around town in your Freightliner, Kenworth, Peterbilt, or Western Star, that diesel engine needs clean air to keep delivering the power and fuel economy you’re counting on. A clogged or dirty air filter chokes down power, increases fuel consumption, and lets dirt into places where it doesn’t belong. This Baldwin air filter catches all that road dust, pollen, and debris before it can cause expensive engine problems.

What You’re Getting

  • Massive 11 13/32 inch outer diameter with nearly 24 inch length provides huge filtration capacity for long service intervals
  • Built-in 3 3/4 inch dust ejector hole helps remove heavier particles before they reach the filter media
  • Inside-out flow direction design maximizes dirt-holding capacity and extends filter life
  • Baldwin quality construction that handles highway vibration and temperature extremes
  • Direct replacement that fits your existing air cleaner housing perfectly

Built for Heavy-Duty Work

This filter is designed for the big commercial trucks that keep America’s freight moving. Whether you’re running a long-haul tractor across the interstates, delivering construction materials to job sites, or hauling agricultural products from farm to market, these trucks work hard in all kinds of conditions. The large capacity handles the high airflow demands of heavy-duty diesel engines while providing the filtration protection they need.

Made to Last

Commercial trucks can’t afford unscheduled downtime, so this filter is built to handle the punishment. Baldwin’s been making filters since before most of us were born, and they understand what it takes to protect engines that run hundreds of thousands of miles. The robust construction and quality filter media keep doing their job mile after mile, protecting your investment in expensive engine components.

Installation Notes

This is a straight replacement for your factory air filter—just remove the old one and install the new. The dust ejector hole should face down when properly installed. While you’ve got the housing open, check the air intake piping and clamps for any leaks that could let unfiltered air bypass your expensive filtration system.
