CSF Premium Performance Engine Oil Cooler – Direct-Fit Upgrade for BMW M5 Models (F10, F90, G90)

Description

The CSF High-Performance Engine Oil Cooler (SKU 8317) is a robust, drop-in performance upgrade designed for BMW S63-powered vehicles including the F1X M5/M6 and F9X M5/M8 platforms. As tuned and high-output builds push engine temperatures higher — especially under track or spirited driving — the stock oil cooler can struggle to keep oil temperatures in check. This CSF unit replaces the OEM cooler with a heavier-duty bar-and-plate core and reinforced construction that delivers significantly better heat dissipation, improved durability, and protection against failure. It’s an essential cooling component for high-performance or modified S63 engines that see regular high load or track use.

Fitment Notes

• Designed for BMW M5 (F10, F90), M6 (F12/F13), and M8 (F91/F92/F93) models equipped with the 4.4 L twin-turbo S63 V8.

• Also fits related chassis including BMW M850i xDrive and newer G90/G99 M5 variants in select years.

• Direct OEM part replacement for BMW oil cooler (replaces OE part numbers 17212284260 & 17228746756).

• True plug-and-play drop-in fitment, although trimming of lower radiator support or ducting may be recommended for best clearance/fit depending on vehicle and setup.

Included

• CSF High-Performance engine oil cooler with 60 mm thick bar-and-plate core.

• CNC-machined brackets and OEM-style inlet/outlet connections for direct fit.

• Leak- and pressure-tested assembly with quality-tested construction.

• Installation guidance/documentation (varies by retailer).

Product Specs

• Core Type: High-efficiency bar-and-plate core — more durable and heat-rejection-capable than OEM tube-and-fin design.

• Core Thickness: 60 mm (2.36″) — approximately 33% larger than OEM’s ~45 mm core, increasing oil cooling capacity and surface area.

• Material: Aluminum core and end tanks with satin black finish for corrosion resistance and longevity.

• Construction: 100% TIG-welded cast end tanks and reinforced materials for improved durability.

• Oil Capacity: Core redesign increases total oil cooling capacity by ~0.5 quarts (0.47 L).

• Installation: Plug-and-play direct replacement — may require slight trimming of OE ducting or cradle for optimal routing.

• Warranty: 2-year limited warranty from CSF.

Product Features

• Significantly improved oil cooling efficiency compared to stock cooler — reduces peak oil temperatures during high-load driving or track sessions.

• Robust bar-and-plate core design resists impact and heat stress better than fragile tube-and-fin OE units.

• Reinforced TIG-welded construction and CNC-machined connections improve durability and leak resistance.

• Plug-and-play OEM-compatible fitment simplifies installation and preserves vehicle fluid routing.

• Larger core volume and increased fin rows maximize heat dissipation and enhance long-term oil health.

• Essential for tuned or high-output builds where factory cooling falls short and excessive oil temps can trigger engine safety modes or degradation.
