CSF Classic & Small Chassis Audi 5-Cylinder High-Performance Radiator
In parternship with our friends at INA engineering, CSF radiators put together a fantastic high performance radiator for all classic small chassis audis (4000, Ur Quattro, 80, 90). Built with connection provisions with or without an auxillary front radiator and air conditioning.
The CSF radiator features a 2-Row 42mm aluminum core that not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat CSF's exclusive B tube technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. CSF’s thin ultra efficient core allows the radiator to be mounted in the factory location with original ducting and requires no modifications or cutting. In contrast, other aftermarket aluminum radiators on the market use a massive 3-row core that requires modifications and cutting to install.
The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. Additionally, the satin black finish gives the radiator a clean OEM look.
