Both the 964 and 993 ran hotter than earlier air-cooled 911s for a variety of reasons. Increased performance output, new emissions regulations, and limited space in the engine bay were all contributing factors. Porsche was definitely stretching the limits of air/oil cooling. Especially given the cooling technology and design of that day and age.
Following the incredible success and enthusiastic response to the CSF 911/930 Turbo Fender Oil Cooler (#8168), CSF has expanded its Porsche performance lineup with a modern OEM+ upgrade for the last of the air-cooled 911s. Introducing the all-new CSF OEM+ Performance Engine Oil Cooler for the Porsche 964 and 993.

DESIGN & ENGINEERING
To develop a truly modern cooling solution for the 964 and 993, CSF once again partnered with Porsche engine building and restoration experts at SV Auto. Their deep expertise in engine restoration and air-cooled performance provided CSF with key insights that shaped the design of this next-gen cooler. Leveraging technology from the best selling G-Body Engine Oil Cooler (a project that took over 18 months and a $20,000+ R&D investment) this new cooler brings the best modern engineering to the 911.
Engineered to fit seamlessly into concours-winning restorations, this CSF oil cooler retains a factory-style look while delivering cutting-edge performance and technology. Whether you’re restoring a classic 964/993, building a high-horsepower restomod, or prepping a car for the track, this is the ultimate OEM+ and performance cooling upgrade for your 911.
TRUSTED BY WORLD RENOWN SHOPS & BUILDERS
Pfaff Tuning has been working with the 964 platform to pursue true OEM+ perfection since 2012. They have created a unique Bespoke program aimed at delivering the ultimate driving and ownership experience for 964 enthusiasts. Their expert team handles everything from standard maintenance to full restorations and custom builds.
First impressions of unboxing the cooler were of the high level of quality. Fitment was no different. All the OEM lines, shroud and hardware fit perfectly in place as if the cooler was OEM. CSF looks forward to using these coolers on all CSF’s 964 project cars going forward. Using any oil cooler other than CSF just makes no sense.

CSF VS OEM
The original Längerer & Reich oil cooler for the Porsche 964 and 993 was designed back in the 1980s. While it was cutting-edge at the time, it has definitely started to show its age. Even though OEM replacements are still available through the Porsche Classic program, they are built with the same outdated technology and materials as they were 30+ years ago. Replacing a clogged or failing unit with a OEM cooler may fix the immediate issues, but it won’t deliver any real improvement in performance or reliability.
Key Features
The new CSF oil cooler for the 964 and 993 is a true OEM+ upgrade, engineered with modern cooling technology. Its advanced core offers multiple advantages over the original tube and fin design:
Clogged Core on OEM Cooler vs CSF Cooler
The TIG-Welded 100% All Aluminum construction increases the overall strength of the oil cooler. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. It is designed to be a "drop-in fit" solution; mounting in the factory location, working seamlessly with the original fan, and requiring no modifications or cutting. CSF also improved the design of fan shroud mounting locations for easier installation.
- Innovative Rolled Fin Design - Stronger/more durable and Less Clogging
- Wider air passages for improved flow
- 10% Increase in airflow
- 16% Larger Core Volume
- 6% Increase in Heat Dissipation
- No change in oil pressure vs OEM
M30 X 1.5 HIGH-FLOW FITTINGS
CSF drew additional inspiration from its proven 911/930 Turbo Fender Oil Cooler (#8168), incorporating similarly engineered Widemouth fittings. These precision machined, threaded M30 "Widemouth" fittings are designed with an optimized inner diameter (ID) to dramatically improve oil flow.
These fittings deliver up to 50% greater flow capacity compared to OEM connections. Each stainless steel fitting is crafted in-house for superior strength, durability, and long-term reliability under pressure. To ensure a perfect, leak-free seal, CSF pre-installs the fittings with high-quality copper crush washers.
14.5MM ID OF THE OEM FITTINGS VS CSF 17.5MM ID "WIDEMOUTH" DESIGN

PREMIUM PACKAGING
Each cooler is packaged in a premium box with laser cut foam inserts. You can be confident your oil cooler is protected and secure as it is shipped.
AN UPGRADE FOR EVERYONE
Whether you’re restoring a 993 or 964, building a high-performance restomod, or just upgrading for peace of mind, the CSF oil cooler delivers the durability and cooling performance your engine deserves.

Availability & Shipping
Standard Shipping applies to every order — rates are calculated at checkout, with tracking provided once your order ships. Track your order any time at eurospeed.co/pages/track for a live delivery estimate. International delivery is available at checkout, with rates calculated for your location.
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.
Delivery Responsibility
Upon delivery, carefully inspect the item for visible defects or damage before signing for it. If the item is damaged or not as expected, do not accept the package. Once a damaged or defective product is accepted, EuroSpeed cannot cover return shipping costs.
EuroSpeed is not liable for packages marked as delivered by the carrier. If a package is lost, stolen, or missing after being marked as delivered, the customer must file a claim directly with the shipping carrier. Our team will assist with available documentation when needed.
Shipping addresses typically cannot be changed once an order has been marked as shipped. If an address change is possible through the carrier, any carrier redirect, correction, or address-change fee will be the customer’s responsibility.
Please ensure your shipping address is entered correctly at checkout. Orders shipped to incorrectly provided addresses are the customer’s responsibility. EuroSpeed is not responsible for failed deliveries, additional shipping costs, lost packages, or refunds caused by incorrect shipping information, failure to accept delivery, or failure to collect a package from the post office or carrier pickup location within the required time frame.
Customs, Duties & Import Fees
EuroSpeed’s free shipping policy does not include import fees, taxes, duties, clearance charges, or other fees required by your destination country. These charges are the responsibility of the recipient, and EuroSpeed is not responsible for any duties or taxes requested by local customs.
Most shipments clear customs automatically through the shipping provider. However, if additional information is needed to complete the process, our team will assist where possible to help ensure a smooth resolution.
If customs clearance fails and the item is returned or destroyed:
- EuroSpeed reserves the right to deny refund claims.
- Returned items may incur return shipping fees, which will be deducted from any eligible refund.
- Items deemed too costly to return may be destroyed, and no refund will be issued if this occurs.
Package Protection
For added peace of mind, EuroSpeed offers ShipInsure package protection as an optional service at checkout. When selected, this service provides coverage for lost or damaged packages. EuroSpeed is not responsible for shipping delays, lost packages, or damaged items if purchase protection is not selected during checkout.
- Protects against lost or damaged packages.
