As with most vehicles that we built over 20 years ago, the Ferrari F355 is at the age where a lot of the critical components need to be replaced. While the OEM Radiators are still available, they can be quite expensive, and many owners have been looking for a suitable upgrade for their collectable Italian supercars. CSF has listened to the community and has produced the first reputable High-Performance All-Aluminum Radiators for the F355.

Design & Engineering

When initially designing these radiators, there were several key features that CSF knew were important to the Ferrari community: OEM Fit & Finish, Increased performance, and improved reliability.

CSF vs OEM

The original F355 OE radiators from Ferrari feature aluminium cores crimped onto plastic end tanks. While generally accepted as good quality and durable, this design is significantly weaker than the all-aluminium TIG welded design of the CSF Radiators. Anyone who has restored/updated an older car knows the value of having updated parts that are as efficient as possible.

The CSF radiator features a 1-Row 31mm aluminium core that not only increases the fluid capacity of the radiator but also improves the ability of the core to dissipate heat. CSF’s Exclusive B-Tube Technology increases heat transfer by approximately 15% over regular oval welded tubes. The 6.5mm super-efficient multi-louvred fins maximize airflow through the core for the best possible performance. In addition, CSF was able to fit 2 additional cooling tubes and rows of fins.

The combination of TIG-Welded 100% All Aluminum construction and dual-core straps increase the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. Additionally, the satin black finish gives the radiator a clean OEM look and both radiators are a true Plug-and-Play “Drop-in Fit” application.

other Aftermarket

There are a couple of aftermarket options floating around on the internet. While CSF could not find anyone who has tested these units, CSF likes to offer comparison facts for customers to save them time and energy. Typical eBay models may seem tempting based on price, however, they are made in China by an unbranded manufacturer.

While there are plenty of good products made in China, they are usually from well-known brands. These units offer a 1-year warranty and the construction appears to use a low-quality aluminium core with fewer cooling tubes and fin rows than the OEM:

With eBay and unbranded products, you can never be 100% sure of the quality, but with CSF you can. CSF’s factories are ISO certified and are OE suppliers to many US, German and Asian manufacturers. All CSF Radiators are fully manufactured and assembled In-House, Including All Tubes and Fins from Military-Grade (Special Clad) Aluminum (JIS 3003 Spec Minimum). CSF Radiators and components are designed in-house using state-of-the-art software (including Solidworks, Fusion 360, and Unigraphics), and wind tunnel tested for optimal radiator core cooling efficiency.
