PRODUCT DESCRIPTION:

The Audi/VW 1.8L 20v Turbo inline 4 is a great motor. Over the years it has proven stout when making more power and keep the B5 A4’s weight low enough to still be fairly light and nimble. A few bolt-ons, new turbos, and a tune can quickly get you to double the original horsepower of the motor. Unfortunately, these power gains come at the cost of a lot of extra heat.

CSF sought to develop a High-Performance All Aluminum Radiator that would keep up with the needs of enthusiast not only making more power but pushing their Audi’s to the limit. Whether you participate in Auto-X, Drag Racing, Track Driving, or just like hitting the backroads with vigor, the new CSF #7204 is what you need.

The 2-Row 42mm core greatly 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. More cooling rows also contribute to the overall efficiency of the radiator. More cooling tubes means more surface area for the coolant’s heat to dissipate from.

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 harder driving conditions much better than the factory unit.
