Tygeacen Engine Air Filter P621725 for Kenworth T680/T880 & Peterbilt 567/579 — High‑Efficiency Pleated Media, OE Fit

Tygeacen P621725 is a high-efficiency replacement engine air filter designed to protect Kenworth T680/T880, Peterbilt 567/579 and Paccar MX-11/MX-13 diesel engines by trapping dust and particulates while preserving airflow.

This heavy-duty replacement filter (cross-references: P621725, P637453, WA11058, LAF6725, PA32000, LAF67250 and others) is engineered to match OE fit and filtration needs for long-haul and vocational trucks. Built from premium filtration media and reinforced materials, it balances strong contaminant retention with low intake resistance to keep turbocharged diesel engines breathing efficiently in tough conditions.

How does this filter improve engine air intake performance?

The Tygeacen element uses high-efficiency pleated media to capture fine dust and particulates without overly restricting airflow. That combination helps maintain consistent combustion air supply and reduces the load on intake systems over service intervals.

• High dust-holding capacity for extended service life
• Low intake resistance to preserve turbocharger response
• Pleated media increases surface area for better filtration

Will this filter fit my Kenworth, Peterbilt, or Paccar engine?

This unit is manufactured to be compatible with multiple OEM part numbers and truck models, including Kenworth T680/T880, Peterbilt 567/579 and Paccar MX-11/MX-13 applications. Verify fit by comparing the replacement numbers or checking dimensions against your current filter housing before installation.

• Cross-references: P621725, P637453, WA11058, LAF6725, PA32000
• Compatible with common heavy-duty truck intake housings
• Check engine model and OE number for final confirmation

What makes this filter durable enough for commercial use?

The filter is built with a reinforced frame and resilient media that resist shock, vibration, and moisture encountered in heavy trucking. Robust construction helps maintain shape and filtration performance across demanding duty cycles and varied environments.

• Rigid support frame prevents collapse under suction
• Engineered media resists moisture and particulate loading
• Manufactured to withstand road vibration and thermal cycles

How should I service and replace this air filter?

Inspect the filter at regular maintenance intervals or when you notice decreased performance or heavy soiling. Replace the element if the media is clogged, damaged, or if it no longer seals properly in the housing to ensure continued engine protection.

• Follow manufacturer recommended service schedule for your engine
• Inspect sealing surfaces and replace damaged gaskets if needed
• Dispose of used filters according to local environmental rules
