When CSF initially began designing this Audi radiator, the initial target vehicle was the legendary Audi Quattro. Well known for its prowess and racing pedigree, it seemed like the obvious choice for our first 5-Cylinder radiator. However, it did take much digging to realize the radiator for the Quattro was very similar to the radiator of other classic 5-Cylinder Audi models of that era. With this in mind, the CSF Engineering team immediately began working on a model that would fit a wider variety of platforms.
CSF reached out to iABED Industries for their deep knowledge and expertise with older Volkswagen and Audi vehicles. The collaborative effort has resulted in a modular design that can be set up to fit the widest variety of vehicles possible. The CSF #7208 can be set up to be used with or without the Auxiliary Radiator. Multiple fan shroud mounting points allow factory fans from all applications to be mounted without modifications. The top end tank has multiple overflow pipe connection points for factory configuration on all applications. In addition, CSF designed the core with reinforcement straps for additional strength and rigidity. This feature is especially critical due to the vertical mounting configuration and location.
CSF vs OEM & other Aftermarket
The original OE radiator from Audi was a brazed copper and brass design. While generally accepted as good quality and durable, heat exchanger technology has progressed significantly over the decades since these cars were released. Obviously older turbocharged vehicles require the best possible cooling systems but NA engines also benefit from improved cooling efficiency. Anyone who has restored/updated a classic car knows the value of having updated parts that are as efficient as possible.
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.
