Question about this product?

We're happy to help.

The CSF Heat Exchanger features a 2-Row (vs OEM single row) Core that is 42mm thick with CSF's Exclusive B-Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic Transmission, the heat exchanger core specifications were design concurrently with CSF's new Race-Spec Dual Core Transmission Oil Cooler (CSF #8221). The two included Black Rock Guards offer full protection for the heat exchanger (above and below the crash bar), especially when paired with aftermarket "open face" race style grilles. These grilles have become quite popular for performance and aesthetics, and keeping your heat exchanger safe from debris is very important. With well over 100 track hours worth of testing and thousands of miles on the road, you can be assured that the CSF's new High-Performance Front Mount Heat Exchanger has been thoroughly tested and vetted.

  • Includes Black Rock Guards (upper and lower) & Transmission Cooler Mounting Kit - Upper and Lower Rock Guards for Manual Transmission / Upper Rock Guard and Transmission Cooler Mounting Kit for ZF8 Auto
  • 2026 Update: New "Track-Spec" 5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact and Heat Dissipation
  • Tested and Proven by CSF's Global Network of R&D Partners, Including Leading Time Attack Teams, Tuners, and Turbo Kit Manufacturers
  • Significantly Reduces Intake Air Temperatures (IATs) for Maximum Performance (with Faster Heat Soak Recovery)
  • Improves Air Flow to the Rest of the Cooling System for Lower Engine Coolant and Engine Oil Temperatures
