CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions - from road racing to the drag strip.
CSF’s industry-exclusive dual-core design allows for maximum performance and the largest core volume oil capacity without affecting airflow into the rest of the cooling system. No more transmission temperature overheating or expansion tank overflow during racing conditions. Also designed to utilize the OEM top/bottom rubber seals for optimal airflow into the cooling system.

CORE DESIGN
During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with CSF’s industry-leading transmission cooler for the A90/91 Supra and BMW G-Series. Installed in one of the world’s fastest A90 Supra - Titan Motorsports Drag Race Supra (first Supra to reach 8s in the 1/4 mile).

DESIGN & ENGINEERING
Specifically ones that see heavy track/competition use. Transmission oil temperatures have a major impact on the shifting performance of your automatic transmission.
If the fluid passes optimal temperatures you will start to see some delays in shifting. Sluggish shifting can be quite frustrating. However, the real concern is the damage that can be done to the transmission when temperatures get too high. There are often cases where drivers don’t notice the change in shifting performance due to the gradual onset, but the damage is still being done slowly on a very expensive and important component.
DUAL-CORE ADVANTAGE
By changing from the OEM single core design to a dual core, CSF was able to increase the overall volume by 240%. This design offers a drastic improvement in heat dissipation and increases the fluid capacity of the coolers by 130%. 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.
OEM VS CSF
CSF’s industry-exclusive dual-core design allows for maximum performance and the largest core volume oil capacity without affecting airflow into the rest of the cooling system. No more transmission temperature overheating or expansion tank overflow during racing conditions.

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.
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.
By purchasing custom, made-to-order, or oversized items, you acknowledge and accept the extended production, fulfillment, and shipping timelines associated with these products.
Tracking Updates & Delays
All orders receive a tracking number once generated by the courier. Tracking may take 2–3 business days after dispatch to show movement in the courier’s system.
Certain international, oversized, or freight shipments may show limited updates during transfer between fulfillment locations, warehouses, customs, or final-mile carriers. In some cases, tracking is provided or begins updating once the item reaches a regional warehouse, local carrier, or final delivery network.
Shipping timelines are estimates and are not guaranteed. Delays caused by high order volume, weather conditions, customs inspections, carrier disruptions, production queues, warehouse transfers, holidays, or other external factors may occur and are outside of EuroSpeed’s direct control. These delays do not qualify for cancellations or refunds unless the carrier officially marks the package as lost.
