The CSF High Performance Transmission Oil Cooler replaces the factory transmission cooler on B58-powered cars: the Toyota Supra (A90 / A91), BMW M240i (G42), M340i (G20) and Z4 (G29). Its dual-core design stacks two 16mm cores for 240% more core volume and 550ml of fluid capacity against roughly 240ml for the original, which keeps transmission temperatures down and shifting consistent through long or hard sessions at the circuit or drag strip. It fits with no modifications, reuses the factory top and bottom rubber seals and has OEM-style quick-connect fittings, and its 129mm height adds capacity without blocking airflow to the rest of the cooling system. It works with the factory front-mount heat exchanger or with CSF's High-Performance Heat Exchanger (CSF8154), and suits tuned cars, road racing and drag racing.
Features
- Dual-core design with two stacked 16mm cores: 32mm of core (44mm overall) against the 15mm factory core
- Built with CSF's air-conditioning condenser technology: single-row, super-high-pressure 16mm nine-channel microtubes
- 5.4mm tall multi-louvred fins in place of the factory 7mm fins
- Rear cooler has 15 rows (factory 12) plus an additional 12-row front cooler
- 129mm overall height (factory 125mm) adds capacity without restricting airflow
- OEM-style quick-connect inlet and outlet connections
- Reuses the factory top and bottom rubber seals to direct airflow
- Fits with the factory cooling system or CSF's High-Performance Heat Exchanger (CSF8154)
