Fitment and important notes
CSF lists 8280B for 2020 and newer Audi SQ7 and SQ8 models with the turbocharged 4.0L V8. This is the application-specific SQ7/SQ8 system; CSF notes that the earlier 8211/8211R system is not the correct drop-in Exact Fit substitute. Verify the exact vehicle and original charge-air system before ordering.
Manufacturer part number: 8280B
Installation note: Charge-air-system service, fastener torque, seal inspection, pressure testing, and coolant or fluid work must follow CSF and vehicle service information. Professional installation is recommended.
