FASS EGRC20 EGR Filter System
For 2020, 2021, 2022, 2023, 2024 GM 6.6L Duramax L5P
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)
