Audi B5 S4 Core Support with Radiator
Both the core support and the radiator for the Audi B5 S4 are available from various online retailers as separate components, with high-performance aftermarket options and OEM-style replacements readily accessible.
Core Support Options for the Audi B5 S4 Core Support with Radiator
The original core support for the B5 S4 is made from a fiber-plastic composite, which can become brittle over time. Aftermarket aluminum units are a popular, more durable upgrade.
- George VanBuren B5 Aluminum Core Support: This is an aftermarket, laser-cut 5052 and CNC-machined 6061 aluminum unit designed to replace the OEM part.
- Rigidity/Flexibility: Offers more rigidity and flexibility for mounting aftermarket components like larger intercoolers.
- Fitment: It features interchangeable upper and lower radiator mounts that fit the B5 A4 and S4 radiators, with options to move the radiator to alternative locations.
- Audi B5 S4 OEM Radiator Core Support Lock Carrier: This is a genuine OEM part available as a replacement for the factory unit.
- Availability: These are often available as used parts in good condition from specialized Audi recyclers and online marketplaces.
Radiator Options
Performance radiators are a common upgrade for the B5 S4 platform, especially for modified vehicles, as the 2.7T engine can generate significant heat.
- CSF High-Performance All-Aluminum Radiator (P/N: 7071): This is a widely recommended upgrade for high-horsepower builds and track use.
- Technology: Features CSF’s exclusive “B-Tube” technology and a multi-louvered fin design, which increases heat transfer surface area by approximately 15% over regular O-shape tubes.
- Fitment: It is a “drop-in fit” design, requiring no modifications to install and accepting all OEM components, including the AC condenser and fan shroud.
- Construction: It has a 2-row, 42mm core and is made from 100% TIG-welded aluminum for enhanced durability.
- OEM Style Radiators: Various brand-new, standard replacement radiators are available from retailers online, designed to meet OE specifications for a direct fit
