CSF is well known for making the best A9X Supra and BMW G-Series cooling systems on the market. Naturally, they have been most successful with the B58 crowd. With years of feedback from Customers, Race Teams, and Development Partners, CSF has more B58 cooling experience than any other company in the world.
With more and more people pushing the limits of the Supra, the factory radiator has started showing its limitations. Bigger turbos cranking out more power create a lot more heat that needs to be dissipated. Furthermore, the heat exchanger is mounted directly in front of the radiator, so all the heat shed by the charge air system runs over it. In racing applications this can be detrimental to engine coolant temperatures and risk sending your Supra into limp mode. In addition, many of these cars are getting to an age where wear and tear necessitates replacement.

CORE DESIGN
CSF began development of the Supra radiator over 1 year ago with thorough race testing done by Titan Motorsports and Studio RSR. To give customers the best possible performance, CSF incorporated its latest 5mm fin cooling technology. This new fin technology increases the heat transfer area over a traditional radiator by 20-25%. The original OE radiator from Toyota/BMW is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, there is always room for improvement. The 4mm fins on the OE radiator made the system fairly efficient for a factory unit. The core itself is one of the biggest limiting factors at only 34mm thick and a single cooling row. With data collected by development partners and race teams, CSF was able to design the ideal High-Performance replacement. The CSF radiator features the latest 5mm fin technology. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is much larger than the factory featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting. CSF understands that this radiator will be used in motorsport competitions. While it would have been easy to engineer a good radiator and call it a day, CSF wanted to make the best possible radiator that would hold up under the most demanding conditions. This requires more development time with a lot more testing, but the result is the ultimate performance radiator you can depend on. CSF worked closely with two R&D Partners to test the radiators in multiple motorsport environments. These initial test units were made using CSF’s 42mm 2-Row core with 6.5mm fins. Titan Motorsports was the perfect partner to test the radiator for drag racing applications. CSF has a long relationship with the team at Titan Motorsports. They have one of the fastest A90 Supras in the world and compete in drag and roll racing competitions across the US. Over the past year, the Supra has been run in countless competitions in some of the hottest and harshest environmental conditions. Over the past year, the radiator has performed very well offering lower engine temps at both idle and during runs. For road racing applications, CSF worked closely with long-time R&D Partner Studio RSR. Their "Project Silver Speed" A90 Supra is a true road race vehicle that competes in a wide variety of events. Studio RSR ran the CSF prototype radiator through the complete season of Global Time Attack. They also ran the car at the 101st Pikes Peak International Hill Climb. Throughout their testing they saw lower maximum engine coolant temperatures as well as faster recovery times. While the 6.5mm fin version performed extremely well in testing, CSF always seeks to offer the ultimate cooling solution. Before going into final production the design was updated to incorporate CSF’s latest 5mm fin technology which was introduced at the end of 2023. This new core specification offers even more heat transfer area and thermal efficiency than the tested prototypes. CSF is confident this radiator is ready to take on the most demanding racing conditions in the world.

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.
Custom, Made-To-Order & Oversized Items
Custom, made-to-order, and oversized product categories may include carbon fiber steering wheels, hoods, trunk lids, fenders, front lips, splitters, side skirts, diffusers, bumpers, body kits, widebody components, select spoilers, rear wings, and other large carbon fiber components.
Many carbon fiber items are made to order. Some products may already be stocked and ready to dispatch when available, but if inventory is unavailable, your purchase reserves the next available production slot instead of waiting for a separate restock listing.
Production time: Production can take 1–4 weeks depending on product type, selected options, finish, current queue, and quality-control timing.
Shipping time: Shipping can take 2–10 weeks depending on item size, freight method, destination, customs processing, carrier delays, warehouse transfers, and final delivery location. Carbon fiber steering wheels typically ship faster, with shipping usually taking 3–7 business days after dispatch.
