Product Description

The CSF 8132 is a high-performance, race-grade, all-aluminum quadruple-pass radiator designed for VAG MQB platform vehicles including the 2015-2021 Volkswagen Golf R, 2015-2020 Audi S3, and 2016-2020 Audi TT/TTS. This multi-fit component installs on the left side as a DSG transmission water-to-oil heat exchanger or on the right side as an auxiliary engine coolant radiator, using factory mounting points with no modifications required. The 2-row 42mm core features CSF's exclusive B-Tube technology, increasing heat transfer surface area by approximately 15% over conventional oval tubes while maintaining a lighter, stronger construction. The quadruple-pass flow path delivers a 42% increase in flow area and 36% increase in heat rejection over the factory cooler. CNC machined brackets and fittings ensure precise fitment, while the included removable metal rock guard protects the core from road debris. For vehicles driven hard on track, CSF recommends pairing this unit with the CSF #7084 triple-pass main radiator and installing a second 8132 on the auxiliary side for a complete MQB cooling system solution.
