F8X M3 / M4 / M2 Comp Top Mount Charge-Air-Cooler - Raw Finish
Pushing your S55 powered F8X hard exposes the limits of the factory top mount charge-air-cooler. After consecutive dyno pulls or track laps, power drops and intake temps climb. The CSF Top Mount Charge-Air-Cooler in Raw Aluminum keeps your M3, M4, or M2 Competition running strong, letting boost air stay dense and engine performance consistent. Every pull feels sharper, turbo spool quicker, and the car responds the way it was meant to.
CSF engineers refined this cooler through dyno testing, CFD analysis, and track sessions. The 60 percent larger dual-pass core with cross-flow design keeps intake temperatures under control far better than stock, allowing your engine to maintain power under the harshest driving conditions. Every endtank and air divider is optimized for maximum airflow and heat transfer efficiency.
Precision Engineered Design
Worlds first cast endtank top mount cooler for the BMW S55 engine. Dual-pass cross-flow core with 2 stage water cooling. Multiple cast air dividers for optimized airflow. Core crafted in raw aluminum with option for custom powder-coating. 3D scanning and rapid prototyping ensures precise fitment. OEM style quick-connect water connections and sensor ports included. Drop-in fit requires no modifications. Lifetime warranty.
Configuration Options
Available in raw aluminum (CSF #8082R) or professional crinkle black powder coat (CSF #8082). Works with the full CSF cooling suite including the front mount heat exchanger.
Exhaust Tips & Customization
Not applicable. This upgrade focuses entirely on intake charge cooling and heat soak reduction.
Production & Lead Time
Made to order with strict quality control. Production time prioritizes precision and performance. Built to handle street abuse and serious track use without compromise.

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.
