CSF 97-02 Audi S4 (B5) Radiator

The new all-aluminum high performance radiator from CSF is a 2-row 42mm core in a triple-pass configuration.

If you’re looking to modify, upgrade, or simply keep up with the maintenance on an Audi B5 S4, upgrading the cooling system with new CSF’s high-performance all-aluminum radiator is highly recommended CSF #7071. It’s another crucial fix along with a laundry list of other items to replace and maintain on the iconic Audi B5 S4. Keep in mind that these cars are 15-20 years old, and if you haven’t already had to replace your original plastic tank radiator, the time is definitely coming soon!

CSF’s triple-pass technology allows the coolant to flow through the radiator core 3x rather than just flowing across the surface of the core once. This allows much colder ambient air to exchange heat with the coolant for a 3x longer period of time generating the lowest outlet temperature possible. Still with a drop-in fit!

Nice!
Color: Brown, Size: XX-Large
A lot better made than I anticipated. Looks and feels like suede. For my needs, it was perfect for a costume. Fits well, and looks more expensive.

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.
