P621725 PowerCore Air Filter for Kenworth T680 & Peterbilt 579

The P621725 is a PowerCore G2 engine air filter engineered for Kenworth T680, T800, T880 and Peterbilt 567 and 579 trucks. This advanced panel-style element uses Donaldson's proprietary PowerCore filtration technology to deliver high-efficiency air cleaning in a compact, easy-to-service package.

Key Features

• PowerCore G2 technology — ultra-fine fluted media channels for maximum surface area
• Compact dimensions (483 × 213 × 309 mm) reduce housing size requirements
• No inner filter element required — simplifies replacement and reduces parts cost
• Designed for both on-road and off-road heavy-duty environments

Next-Generation Filtration

Unlike traditional radial seal filters, the PowerCore G2 design uses straight-through fluted media channels that capture contaminants along the entire length of the element. This architecture provides more filtration surface area per unit of volume, resulting in longer service life, lower restriction, and better overall engine protection.

Vehicle Compatibility

Direct fit for Kenworth T680, T800, and T880 as well as Peterbilt 567 and 579 trucks. Cross-references to Baldwin PA32000 and WIX WA11058.
