CSF Race Radiator & Cooler Bundle - F3X 335i/435i M Sport, M235i Racing

All of the radiators and coolers for a M Sport F30 335i or F32 435i cooling system upgrade and overhaul. This also works with F22 M235i Racing/M240i Racing models. When they don't want to gamble on a race car's cooling system many of the top racers turn to CSF. No other company provides as wide a range of cooling upgrades as CSF. This is not a "like-for-like" replacement approach. CSF has their own cooling fin design, 3D scanning technology, and a depth of motorsport experience that others cannot match. Each CSF piece is a premium high performance component with a level of quality and craftsmanship that is usually found in products with a much higher price point.

Note: this package is intended for race-prepped F30/F32 cars that have had some of the street-car comfort features removed, such as the A/C condenser and associated plumbing (also applies to M235i Racing). While patterned after stock parts some minor trimming or modification may be required on other stock parts for clearance purposes. This is the trade-off to be expected for maximum cooling effectiveness.

CSF Triple-Pass Race-Spec Radiator. Aluminum radiator for is a factory replacement using all factory shrouding, clip-on hoses, and mounting points. This racing radiator is designed to fit with the A/C condenser removed. With the condenser removed all other parts are a direct fit, including OEM hoses, mounting brackets, and fan shroud. CSF uses new technology packed into a compact two-row design for better cooling capacity without the added weight. More efficient B-tubes have greater surface area for cooling (15% cooling capacity increase in fin technology alone) and a precision multi-louvered fin to increase heat rejection performance and surface area contact. Additionally, this CSF part has more total cooling tubes, and a three-pass flow design for maximum cooling in race environments and extreme driving conditions.

Genuine BMW Remote Auxiliary Radiator. This is the small radiator located in the left/driver's side bumper and provides additional coolant capacity and cooling surface area.

CSF Race-Spec Oil Cooler. The CSF engine oil cooler is a larger core along with a piggyback cooler that sits behind the primary for an additional 6 rows of cooling and another half-quart of oil capacity. The better cooling performance reduces the potential for temperature-related faults and limp mode encountered during track events. CSF saw a 40° improvement in oil temp on a 115° test day. They actually experienced limp mode during testing of the stock cooler which was remedied with the install of the CSF 2-Core system. No modification is required for install - reuses all of the factory connections, mounting points, and shrouding. New oil line o-rings included.

CSF Front Intercooler. CSF FMIC is two intercoolers merged into one larger unit. The standard oversized intercooler is enhanced by a taller intercooler in front. This maximizes the available surface area in the front bumper but does not require any modifications for installation. It uses all of the factory connections and install points for a plug and play fitment. 3D scanning and rapid prototyping allowed CSF to take advantage of the available exposure. A bar and plate design has excellent cooling capability which makes this ideal for street cars. New o-rings included.

M235i/M240i Racing Homologation: these parts, with the exception of the aux radiator, do not meet the original homologation rules for the M235iR/M240iR. If your racing series still requires the original homologated parts please contact us for an alternative package.
