CSF BMW F-Chassis B58/B48/B46 Front Mount Heat Exchanger with Rock Guard
CSF BMW High Performance BMW B58 / B48 Heat Exchanger
***Product Update October 2019 Production***
CSF’s pursuit of cooling perfection continues with improvements to The Ultimate BMW B58 High Performance Heat Exchanger. As of October 2019, CSF has released a new and improved “Version 2.0” of the BMW B58 Heat Exchanger. Improvements include the following Three (3) key updates:
- Upgraded inlet/outlet design with new tapered entry and exit points from end tanks, resulting in optimized water flow and increased performance (matches OEM spec).*
- After extensive wind-tunnel, dynamometer (rolling-road test), and field testing, CSF engineers have improved the core spec from Version 1’s 68mm 2-row core with 8mm fin height to Version 2’s Ultra-efficient 42mm 2-row core, with CSF’s B-tube technology, and 6.5mm multi-louvered fin height. *
- Increase of 15% more cooling tubes used in the core vs. V1 design for better surface area contact and heat dissipation.
- Results in optimized airflow through the heat exchanger core and into other cooling system components for maximum performance of the entire cooling system. (Especially critical if installed in an X-Drive model with transmission oil cooler placed in front of heat exchanger)
- CSF V2 design: 2-row 42mm core vs. OEM design: 1-row 26mm core. ~62% increase in core fluid capacity
- Now includes hardware mounting kit* for applications that have a factory transmission oil cooler mounted in front of the heat exchanger (X-Drive models)
The CSF B58 / B48 Triple Pass Charge Cooler Water Radiator is the ultimate cooling solution for race and high performance cars. With increased boost levels, maintaining a consistent intake air temperature throughout extended periods of high demand driving is key. Increased heat robs power in several ways, the main being that hotter air is less dense and results in less oxygen which is key for power and with the hotter air the risk of knock is also increased, to counter this the ECU will introduce its safety protocols to reduce power until the air is cool again.
The CSF all-aluminum Heat Exchanger features an industry leading core design with CSF’s exclusive B-Tube technology along with an ultra-efficient multi-louvered fin height design. To further the cooling efficiency, the integrated three-pass flow system that guarantees the lowest possible outlet temperatures of any upgraded cooling system available for the platform today.

We are typically very quick and have a 24-48 hour turnaround time. Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other.
Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)
Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at email@example.com

If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.
