CSF 8331 High-Performance Heat Exchanger and Transmission Cooler Module for 2020-2025 BMW X3 / X4
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2020-2025 BMW X3 M and X4 M models, including Competition and M40i trims. This CSF high-performance cooling module (MPN 8331) provides a comprehensive solution for heat soak by combining a primary heat exchanger with an integrated transmission oil cooler.
The transmission cooler is constructed using a 1-row, 16mm 9-channel microtube for optimized fluid flow and maximum surface area, resulting in a 201% increase in core volume over the factory unit. To protect the core from debris, CSF includes an integrated rock guard, addressing a critical vulnerability in the OE center cooling stack. The heat exchanger utilizes CSF's B-Tube technology with 6.5mm multi-louvered fins and a dual-row 42mm core for superior thermal rejection and faster recovery of intake air temperatures (IATs).
- Fits 2020-2025 BMW X3 M / X4 M (M, Competition, M40i)
- 100% all-aluminum TIG-welded construction with hand-brushed satin finish
- Heat Exchanger: 2-row, 42mm ultra-high-performance core with B-Tube technology
- Transmission Cooler: 16mm 9-channel microtube design with 201% volume increase
- Integrated rock guard for protection against track and road debris
- Plug-and-play installation with CNC machined mounting brackets and OEM-style quick-connect fittings
- Pre-installed foam strips for optimized air sealing
- Manufacturer Part Number: 8331
- 2-Year Limited Warranty
