Description
Upgrade the performance and cooling efficiency of your BMW M3/M4 with the CSF Front Mount Heat Exchanger and Top Mount Dual-Pass Charge Air Cooler Combo Deal. This product is designed to provide superior cooling efficiency and optimal performance for your car.
The CSF Front Mount Heat Exchanger features a 2-row 42mm core with exclusive B-tube technology, an ultra-efficient fin with 6.5mm fin height, and a multi-louvered design for maximum surface area contact. Its dual-pass flow structure allows coolant to flow across the core of the radiator twice for the lowest outlet temperature possible. The CNC machined OEM-style "quick-connect" inlet/outlet connections and mounting brackets ensure superb fit and durability. The product also includes a removable aluminum rock guard, all-aluminum race style drain plug, and a one-hour "mirror finish" hand polish. The drop-in fit design requires no modifications to install and accepts all attaching OEM components, including "quick-connect" hoses, mounting brackets, OEM X-brace, and all air ducting/shrouding. Plus, it comes with a lifetime warranty for your peace of mind.
The CSF Top Mount Dual-Pass Charge Air Cooler is the world's first cast end tank designed for the BMW S55 engine in the BMW F8X M3/M4 (F80 M3, F82/F83 M4). It features multiple air dividers cast into both the hot/cold side end tanks for optimized airflow through the custom-designed CSF liquid-to-air intercooler core. The product also has a 60% increase in core size compared to the OEM cooler, a left/right, cross-flow, dual-pass core configuration with 2-stage water cooling for maximum efficiency and intake temperature reduction (vs. OEM single-pass vertical-flow design), and is designed with 3D scanning/rapid prototype technology to ensure precise fitment and maximum surface area utilization. The drop-in fit design allows for easy and quick plug-and-play installation, complete with OEM-style "Quick-Connect" water connections and sensor ports. Plus, it comes finished with a professional "Crinkle Black" powder coat finish or unfinished. This product replaces BMW part number 17 51 7 846 235.
Due to health concerns for their employees, increasing government restrictions regarding social distancing, and an unfortunate break-out of Covid-19 within their polishing center, CSF has adjusted the finish of some of their radiators from their mirror-polished finish to their high-luster satin finish. This adjustment does not affect the great quality, performance, and customer support of the product.
