Ultimate Cooling Upgrade: 1994-2001 Models
Almost every Ferrari that has rolled out of the factory in Maranello has gone on to become an icon of the automotive world. While the Ferrari F355 might not have the same mainstream reverence as some, it is incredibly well loved and has an amazing community supporting it.
It represents a pivotal moment in Ferrari’s history. A bridge between the analog past and the digital future, with a screaming 3.5L 5 valve V8 that provides one of the most celebrated soundtracks in automotive history. For those who own one, the F355 is not just a car. It’s a collectible Italian supercar that deserves the highest level of care and preservation.
As with most vehicles that we built over 20 years ago, the Ferrari F355 is at the age where critical components need to be replaced. The original OEM radiators, with their failure prone plastic end tanks, are a well known vulnerability. While factory replacements are available, they are expensive and utilize the same flawed design.
Recognizing the need for a superior solution, we have produced the first reputable High Performance All Aluminum Radiator for the F355. This is not merely a replacement part. It is a fundamental upgrade to the vehicles cooling system. Our custom radiator was designed to protect your investment, enhance performance, and provide peace of mind for the next chapter of your F355’s life. Explore our shop here.
Why Your Ferrari F355 Needs This Radiator: Eliminating 25 Year Old Plastic Tank Failures
The Ferrari F355 community is one of passion and dedication. Owners understand the unique joy and responsibility that come with maintaining a modern classic. A key part of that responsibility is addressing the known failure points before they become catastrophic problems. The original F355 OE radiators from Ferrari feature aluminum cores crimped onto plastic end tanks. While generally accepted as good quality for their time, this design is significantly weaker than an all aluminum TIG welded unit.
After two decades of heat cycles, vibrations, and exposure to the elements, the plastic becomes brittle and the crimped seals lose their integrity, making failure inevitable. Our high performance radiator was born from listening to the F355 community’s demand for a reliable, high quality upgrade. We engineered a solution that not only matches OEM fit and finish but dramatically improves performance and reliability. By replacing the entire unit with 100% military grade aluminum, we eliminate the root cause of OEM radiator failures.
This is more than just preventive maintenance. It’s an essential upgrade for anyone who truly drives their F355. It ensures that whether you are on a weekend cruise, a spirited backroad, or a demanding track day, your engine is protected by a cooling system that is stronger, more efficient, and built to last a lifetime.
Engineered to Outperform: 25% Better Cooling
When designing this radiator, our goal was not just to fix a problem, but to elevate the car’s performance. The heart of our upgrade is the upgraded 1 Row 31mm ultra high performance dual pass core. This advanced core design increases the fluid capacity of the radiator and significantly improves its ability to dissipate heat. This core features 39 cooling tubes. That is two more than the OEM unit.
We also equipped the industries best radiator with our exclusive B Tube Technology. This proprietary design increases the heat transfer surface area by approximately 15% compared to regular oval welded tubes, providing a substantial cooling advantage. To maximize airflow, we use 6.5mm tall, super efficient multi louvered fins, with 40 fin rows. That is two more than stock.
This combination of a thicker core, more cooling tubes, more fins, and advanced B Tube technology results in an estimated 20-25% improvement in cooling efficiency over the factory radiator. This tangible performance gain means lower and more stable engine temperatures under all driving conditions, reducing the risk of heat related wear and ensuring your F355’s V8 operates at its optimal temperature. It’s a critical upgrade for preserving engine health and unlocking consistent performance.
Comparison: Our Radiator vs. OEM vs. Aftermarket
TIG Welding & Military Grade Aluminum: Built Strong Enough to Outlast Your Ferrari F355
Durability is at the core of our design philosophy. A performance radiator is only as strong as its weakest point, which is why we abandoned the flawed OEM crimped gasket design in favor of a full, 100% aluminum construction. Both the core and the end tanks are crafted from military grade JIS 3003 aluminum, chosen for its exceptional thermal conductivity and resistance to corrosion.
This ensures that every part of the radiator contributes to cooling and is built to last a lifetime. However, the true key to our radiator’s unparalleled strength and reliability lies in how it is assembled. This is done through TIG welding. Every one of our radiators is meticulously TIG welded by expert craftsmen in our ISO certified facility. This process creates a strong, permanent bond that is far superior to the OEM crimped on gasket design.
To further enhance durability, the design incorporates dual core straps, increasing the overall structural rigidity of the radiator so it can hold up to the demands of hard driving conditions. Before shipping, each radiator is individually leak and pressure tested to ensure it is flawless.
The result is a radiator that is not only immune to the common plastic tank failures but is significantly stronger and more durable than the original. The satin black finish provides a clean, OEM+ look, making it a visually appealing and functionally superior upgrade. This rigorous quality control allows us to back our radiators with an industry leading 5 year warranty, giving you complete peace of mind that you are installing the most durable and reliable cooling solution on the market.
The Perfect Fit for All Ferrari F355 Models
Berlinetta, GTS, Spider & F1
A high performance part should not require you to compromise the integrity of your vehicle. We designed our Ferrari F355 radiator to be a true plug and play, “drop in fit” application that requires absolutely no modifications. Our engineers used 3D scanning and state of the art software like Solidworks and Fusion 360 to create a perfect digital model of the OEM unit.
This allows us to manufacture our radiators with CNC machined mounting brackets and OEM style inlet/outlet connections that match the factory locations precisely. The OE location fan shroud mounting points are also retained for a seamless installation.
This radiator is a direct replacement for all Ferrari F355 variants from 1994-2001, including the Berlinetta (and Challenge models), GTS, Spider, and F1. It replaces OEM part numbers 807927 (Right) and 807928 (Left), along with their superseded numbers. Because the F355 uses a dual radiator system, these are sold as individual left and right side units.
Before bringing this product to market, we performed extensive real world testing, installing the radiators into our own F355 project cars here in Los Angeles, CA. This allowed us to verify that all mounting points, hose connections, and fan shroud attachments align perfectly with the factory locations. To top things off, we extensively track test each one of our radiators to ensure they keep operating within our parameters.
This commitment to perfect fitment ensures a straightforward installation for you or your mechanic, preserving the originality of your collectible supercar while providing a vital, modern upgrade. The installation can be completed in 2 – 3 hours by a competent mechanic and requires no cutting, drilling, or modifications to your vehicle. By ensuring a perfect, direct fit, we make the process of protecting your investment straightforward and hassle free.
This isn’t just a replacement radiator. It’s a complete, bolt in cooling system solution that honors the engineering of your Ferrari while decisively improving it for the future. Install it, and drive with the confidence that your F355’s cooling system is finally as robust as its legendary V8 engine.
