CSF BMW F9X X3M/X4M High-Performance Heat Exchanger and Transmission Cooler Module

Manufacturer Part # : 8331

Market Description

• Rock Guard: CSF knows the kind of punishment the front of a car can take on or off the track. The wrong bit of debris flying through the front grille can quickly punch a hole in a cooler. Because the Transmission cooler sits at the very front of the center cooling stack, it is quite vulnerable to damage. The factory grille is the only form of protection for the OEM transmission cooler. However, this still isn't the level of protection many race teams and enthusiasts are comfortable with. To address this concern, CSF has incorporated a rock guard to keep your cooler safe and your X3M/X4M running strong in the event of debris making it through the front grille.
• CSF began designing the Heat Exchanger for the X3M/X4M using all the experience and data gathered from the entire G8X Cooling Suite. The first hurdle in designing a Front Mount Heat Exchanger for these vehicles was the space constraints. The X3M and X4M use a different transmission oil cooler than the G8X models that restricted increasing the size of the Heat Exchanger due to the mounting cradle. After testing a few smaller core options, CSF determined it made more sense to combine the Heat Exchanger with a Transmission Cooler Upgrade to maximize size and performance.
• Dual-Core Advantage: By changing from the OEM single core design to a dual core, CSF was able to increase the overall volume by 201%. This design offers a drastic improvement in heat dissipation and increases the fluid capacity of the coolers. Utilizing CSF's AC Condenser Technology, a 1-Row Super-High Pressure 16mm 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. These features combine to offer the best possible heat dissipation from the system.
• By combining the Heat Exchanger and Transmission Cooler into a full cooling module, CSF was able to run the same size core as the G8X Heat Exchanger. The Auto Transmission Cooler uses the same dual core design as the G8X Transmission Cooler which is fitted to the new Heat Exchanger. This creates a cooling module that comes as a single unit. The combination not only solves two cooling issues for the X3M and X4M, but also lowers costs which are passed along to the customer.
• Heat Exchanger: The TIG welded aluminum tanks are much larger than the OE plastic tanks offering superior strength and fluid volume. A larger 2-row 42mm core increases cooling efficiency and capacity. This high efficiency core uses CSF's Exclusive B-Tube Technology, maximizing airflow and heat dissipation. CSF's multi-louvered fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while maintaining proper airflow.
• Transmission Cooler: The CSF Transmission Cooler features a unique dual pass design to maximize cooling performance. You can see in the diagram below how the OEM Cooler's dual pass design works by flowing across the lower half of the core and back through the top half. This is how traditional dual pass systems work and is perfectly functional. The CSF Front to Back stacked core design more than doubles surface area and almost triples the core volume.
• 100% All-Aluminum construction ensures the best performance and durability. The mounting tabs and brackets are much stronger and more durable than the OE plastic design. In addition, the Heat Exchanger also features an integrated bolt on rock guard to keep the cooler safe. This rock guard is metal and much more robust than the factory plastic rock guard. Now you can feel more confident that your cooling system is safer from debris.
• Many owners have been upgrading their X3Ms and X4Ms with the CSF "Level Up" Charge Air Cooler Manifold for years now. The fastest examples are all running the CSF Manifold and have been asking for more cooling upgrades. After over a year of development and testing, CSF is pleased to announce the Front Mount Heat Exchanger & Transmission Cooler Module for the F9X X3M / X4M.
• The engineers at CSF came up with this unique design to take advantage of the extra space originally taken up by the OE Cooler and oversized plastic cradle. This design essentially doubles the cooling capacity while still fitting perfectly in the OEM position with no modifications necessary.
