The BMW S63 Twin-Turbo V8 is the beating heart of the F1X M5/M6 and F9X M5/M8, delivering incredible performance. Over the years, CSF has been a key player in pushing the power limits of the S63 with its Twin Charge Air Coolers (CSF #8109 & CSF #8178). Today, many M5s, M6s, and M8s are producing well over 1000HP, but with increased power comes increased heat.
As power levels climb, so do oil temperatures, with some owners reporting temperatures exceeding 240°F (115°C) on hot track days. With power limits being pushed further than ever and many of these M cars aging, factory cooling systems struggle to keep up.

CORE DESIGN
Steve Dinan’s Carbahn originally approached CSF about making this oil cooler to compliment their new S63 Stroker Kit. Carbahn engineers worked closely with CSF to design an oil cooler that could handle the power and heat increases. Now, CSF is proud to introduce the High-Performance Engine Oil Cooler for the F1X M5/M6 & F9X M5/M8, a must-have upgrade for S63 owners.
DESIGN & ENGINEERING
CSF collaborated with the team at Carbahn to ensure maximum compatibility and performance, creating a drop-in solution for both platforms. Designed specifically to handle the extra heat of their new S63 Stroker Kit, this oil cooler is built for ultimate performance and power.
However, performance isn’t the only reason to upgrade. Many F1X & F9X owners have been forced to replace their oil coolers due to leaks and damage, largely because of their vulnerable mounting position; a problem that worsens with lowered suspension setups. A stronger, more robust design was needed to solve these issues.
CSF VS OEM
The original OE oil cooler from BMW is an all metal design which would make you think it would be fairly robust. However, there are several weak spots in the design that make it far less durable than it could be. The CSF design resolves these issues with more robust materials and reinforcing weak points.
At first glance, the original BMW OE oil cooler appears solid due to its all-metal construction. However, design weaknesses make it far less durable than expected. CSF tackled these flaws by using stronger materials and reinforced engineering to create a superior replacement:
With enhanced cooling performance, increased durability, and precision engineering, CSF’s new High-Performance Engine Oil Cooler is the perfect solution for S63 owners pushing their cars to the limit.
CSF Oil Cooler (#8317)
BMW OE Oil Cooler (17212284260)
- CNC-Machined Connection Blocks - TIG-welded for extreme durability, ensuring they withstand any abuse.
- Upgraded Core Design - Swaps the fragile Tube & Fin core for a heavy-duty Bar & Plate core, making it far more impact-resistant in case of a front-end scrape or bottom-out.
- 33% Larger Core - Features three additional rows of oil cooling and a thicker 60mm core (vs. OEM 45mm core) for improved heat dissipation. Oil capacity is increased by 0.5 quarts (0.47L).
- TIG-Welded End Tanks - Stronger and more durable than the factory’s brazed construction, reducing the risk of leaks.
AN ESSENTIAL UPGRADE FOR ANY F1X/F9X/G9X
Whether your M5, M6, or M8 is a daily driver, weekend cruiser, or dedicated track car, upgrading the oil cooler is a smart investment. Tuned S63s, especially those with upgraded turbos, generate significantly more heat, making efficient cooling even more critical.
Excessive oil temperatures can quickly trigger limp mode and, in extreme cases, lead to catastrophic engine failure. CSF’s new High-Performance Engine Oil Cooler isn’t just about maximizing performance; it is also a preventative upgrade that helps avoid costly repairs and extends the longevity of your engine.
INSTALLATION AT BULLET PERFORMANCE
For the first installation and testing, the CSF F10 M5 was the perfect candidate. The team headed to Bullet Performance in Costa Mesa, California, where the oil cooler install went flawlessly.
While CSF was at it, CSF took the opportunity to upgrade the intake system as well. Thanks to CSF’s good friends at Eventuri, the M5 received a Full Black Carbon Intake System, adding both performance and stunning aesthetics to the engine bay.

Delivery time depends on the product. Most in-stock parts ship within days, while carbon fiber and made-to-order items may require production time before they ship. For the specific timeline on any item, check the Availability & Shipping section on that product’s own page — the guide below covers our general shipping types.
Shipping Overview
Depending on the item, free air freight may be available for select carbon fiber components, with estimated shipping around 1–2 weeks after dispatch. Larger hoods, oversized body components, and certain made-to-order items may require sea freight and longer delivery windows. If timing is important, please contact us at support@eurospeed.co before placing your order.
Shipping Coverage
EuroSpeed ships to customers across the United States and internationally. Shipping is included in the price of eligible products for your convenience and covers the initial cost of delivery to your destination.
Import duties, taxes, clearance fees, or customs charges required by your destination country are not included and remain the recipient’s responsibility.
Order Processing & Fulfillment
Every order is reviewed, processed, and prepared before shipment. Most in-stock products are processed within 1–3 business days, though some orders may take up to 5 business days depending on fulfillment location, product type, order volume, or courier pickup timing.
EuroSpeed stocks select high-demand products at our U.S. facility and international fulfillment centers. Because our catalog includes many vehicle-specific and specialty parts, not every product is held in-house at all times.
Some orders may ship through our trusted fulfillment network, which may include verified manufacturing partners, authorized distributors, regional warehouses, and international fulfillment centers.
- Orders may ship from a U.S. warehouse, international warehouse, manufacturer, or authorized fulfillment partner.
- Some products may require additional handling, processing, production, or quality-check time before shipment.
- Orders enter fulfillment shortly after being placed and may no longer be eligible for cancellation once processing, production, or shipment preparation begins.
