CSF Race-Spec Dual Core ZF8 Transmission Oil Cooler - BMW M2 (G87) / M3 (G80/G81) / M4 (G82/G83) S58 - CSF #8221
Keep your BMW G8X's ZF8 automatic transmission running at optimal temperatures with the CSF Race-Spec Dual Core Transmission Oil Cooler. Developed alongside leading time attack teams and tuners, this cooler is a critical upgrade for any modified or track-driven G8X where rising transmission oil temperatures can lead to sluggish shifting and long-term damage to the gearbox.
The factory single-core transmission cooler is adequate in stock form but falls short on tuned vehicles seeing heavy track or competition use. CSF's dual-core design nearly triples the volume of the OEM unit and increases fluid capacity by approximately 94% (1700ml vs OEM ~875ml), delivering a significant improvement in heat dissipation and shifting consistency under sustained high loads.
Key Features
- Dual-core design with 194% increase in core and tank volume
- 94% increase in fluid capacity compared to OEM (CSF 1700ml vs OEM ~875ml)
- Two 22mm stacked cores = 44mm core thickness (vs OEM 28mm)
- Rear cooler: 16 rows vs OEM 14 rows (191mm overall height vs OEM 155mm)
- Front cooler: additional 16 rows
- 9-channel microtube design using CSF's AC condenser technology for optimal oil flow and maximum surface area
- OEM top/bottom rubber seals retained for optimal airflow
- OEM-style quick-connect inlet/outlet connections
- Includes replaceable rock guard for debris protection
- Drop-in fit — no modifications required
- Compatible with CSF Front Mount Heat Exchanger (CSF #8215) or OEM cooling system
- Replaces OEM BMW part number 17-11-8-095-284
- 2-year CSF limited warranty
