BMW F3X/F2X B58/B48 Triple-Pass Heat Exchanger w/ Rock Guard - Black
Feel the difference the moment you hit boost with the CSF BMW F3X F2X B58/B48 Triple-Pass Heat Exchanger. Your turbocharged engine stays cool even when you push hard, keeping charge air temperatures low and power delivery consistent. Say goodbye to heat soak and limp mode, and enjoy every pull with confidence. This is the kind of upgrade that makes your car feel sharper, more responsive, and ready for the track or canyon runs.
CSF put in the hours on dyno and real-world testing to make sure this heat exchanger performs under the harshest conditions. Every triple-pass core is tuned to handle high-output B58 and B48 engines, and the satin black finish keeps it looking clean and OEM plus under the hood. Track sessions, spirited drives, or daily blasting, this cooler keeps your engine performing at its best without compromise.
Precision Engineered Design
Constructed with a 68mm two-row core using CSF's B-Tube technology, this is the largest two-row core in the industry. The triple-pass flow design ensures coolant passes through three times for the lowest possible exit temperatures. CNC machined mounting pins and brackets allow for plug-and-play installation. Detachable rock guard included to protect your investment. Semi-gloss black finish for that stealth OEM plus look. Core dimensions 524mm by 478mm by 69mm.
Configuration Options
Currently available as a single variant with satin black finish. Polished finish option also exists (CSF 8131). Designed for all turbocharged B58 and B48 F2X and F3X BMW platforms listed below.

About Us
What started as a group of BMW enthusiasts tired of overpriced parts and limited options is now a brand trusted by thousands of owners nationwide.
We designed our own product lines from the ground up and built the production infrastructure to make them happen. No middlemen, no compromises. Just the parts we actually wanted on our own builds.
Now we operate out of Oceanside, California, engineering valved exhaust systems, carbon fiber, forged wheels, front-mount intakes, and more. Everything is designed in-house, tested on real platforms, and stocked locally for fast shipping.
This is just the beginning.
