EGR Filter System for GMC/Chevrolet 6.6 Duramax 2020-2025

The FASS EGR Filter System is a revolutionary upgrade for the 6.6 L5P Duramax engine. By removing 85% of the particulate matter that would otherwise circulate throughout your engine, this Filtration System drastically improves long-term reliability.

Without the FASS EGR Filter in place, particulate matter (soot) builds up throughout your EGR system and engine, causing premature wear and ultimately failure of vital components. By installing the FASS EGR Filter, you’re eliminating 85% of the particulate matter that could otherwise damage your engine.

Unfiltered EGR Systems can lead to:

• Clogged EGR coolers
• Clogged EGR valves
• Particulate matter buildup in intakes
• Particulate matter buildup on grid heaters
• Particulate matter buildup on intake valves
• Particulate matter buildup on top of piston rings
• Excessive particulate matter introduced in your engine oil

FASS EGR Filter System benefits:

• Filters out 85% of particulate matter from the EGR stream
• Extends the life of the EGR cooler and EGR valve
• Reduced particulate matter build-up on grid heaters
• Reduced particulate matter build-up on intake valves
• Reduced particulate matter build-up inside intakes—allowing proper airflow
• Reduced particulate matter build-up piston rings which minimizes the possibility of broken rings and engine failure
• Reduced soot content in engine oil (verified by oil sample analysis)
