It uses Donaldson PowerCore stacked-pleat cellulose media in a panel form factor to provide high filtration efficiency (99.95% per ISO 5011) and extended service life. Designed for Kenworth T680/T880 and Peterbilt 567/579 models with Paccar MX-11, MX-13, or Cummins ISX15/X15 engines, it protects the engine from dust and contaminants while maintaining proper airflow for fuel efficiency and power. Replace the filter when it becomes clogged or at recommended service intervals to prevent engine damage and performance loss.
