BMW G8X M3/M4 ZF8 HIGH-PERFORMANCE AUTOMATIC TRANSMISSION COOLER

Part #8221

The new CSF transmission oil cooler for the ZF8 automatic in the G8X M2/M3/M4 is engineered for high-performance and track-use applications. Featuring a unique dual pass design, the CSF Transmission Oil Cooler nearly triples the volume of the OEM unit and increases fluid capacity by ~94%.

The core features advanced micro-tube condenser technology derived from CSF's A/C cooling systems. Its 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. Installation is plug and play with the drop-in fit design. The CSF cooler retains OEM quick-connects and includes a replaceable rock guard for additional protection from road or track debris. This packaging helps preserve shifting performance, maintain optimal transmission oil temperatures, and extend transmission life in modified or race-prepped G8X M Cars.
