CSF MQB Aluminum Triple-Pass Water Cooler (Racing)
VAG MQB platform
High-performance water cooler made entirely of aluminum – designed for maximum cooling reserve, stable water temperatures and constant performance under continuous sporting load.
Description
The CSF MQB aluminum triple-pass water cooler (motorsport) is a significant cooling upgrade for high-performance vehicles based on the VAG MQB platform . Compared to the standard solution, the CSF cooler utilizes the available installation space much more efficiently and employs a triple-pass design , in which the coolant passes through the radiator core three times . This increases the residence time in the heat exchanger, resulting in lower outlet temperatures and more stable cooling under load.
Technology & Construction
- All-aluminum construction for high thermal resistance
- 2-row 42 mm core for significantly more cooling volume
- Triple-pass flow guidance for maximum heat dissipation
- B-Tube technology with optimized internal surface (efficient heat transfer)
- CNC-machined quick-connect fittings for a clean fit
- Race-style drain valve for easy, service-friendly emptying
- Drop-in fit – no modifications to the vehicle necessary
Cooling performance & driving operation
- Significantly higher cooling reserve during sporty driving.
- More stable water temperatures under heat and continuous load
- Reduced risk of temperature-related performance degradation
- Ideal addition for vehicles with a large intercooler and increased performance.
Advantages over stock coolers
- More cooling surface area and significantly higher cooling volume
- More efficient heat dissipation through triple-pass layout
- More robust design for higher performance levels
- Motorsport-oriented durability
compatibility
- VAG vehicles on MQB platform (vehicle and engine dependent)
The exact configuration depends on the model, engine type, front end package, and radiator package. The manufacturer's instructions apply for installation.
