Ferrari 488 F8 Radiator Intercooler Right 328422 748559

the part numbers 328422 and 748559 refer to the Right-Hand Side Intercooler Radiator for the Ferrari 488 (GTB/Spider) and the Ferrari F8 (Tributo/Spider).

Because these cars share the same F142 twin-turbo V8 engine architecture, the intercooler system is largely consistent, though part numbers have been updated (superseded) over the years to reflect minor manufacturing improvements.

1. Technical Identification

• Part Number 328422: Typically the primary identification for the 488 series intercooler.

• Part Number 748559: Often represents the updated or “superseded” part number found on newer F8 models or as a revised replacement part for the 488.

• Position: Right-Hand Side (RHS).

• Type: Air-to-Water Intercooler Heat Exchanger.

• Function: Cools the intake air charge after it has been compressed by the right-side turbocharger, which is critical for maintaining horsepower and preventing engine knock.

2. 2026 Market Pricing (Estimated USD)

These radiators are high-precision aluminum components. Prices vary depending on whether you source them from a dealer or a specialist.

3. Compatibility: 488 vs. F8

• The “F8 Upgrade”: While the 488 and F8 use very similar cooling layouts, the F8 Tributo features improved thermal management. Part number 748559 is often cited as having slightly optimized fin density compared to the early 328422 units.

• Physical Fit: They are physically interchangeable in the mounting brackets for both the 488 and F8. If you are replacing one side on a 488, it is generally okay to use the newer 748559 part.

4. Common 2026 Failure Modes

• Stone Puncture: Since these radiators sit behind the side air intakes, they are highly susceptible to “sandblasting” and stone impacts. In 2026, many owners install Radiator Guard Grills to prevent this.

• End-Tank Leaks: The vibration of the twin-turbo engine can eventually cause hairline cracks at the seams where the aluminum core meets the end tanks.

• Debris Clogging: Leaves and road debris often get trapped between the intercooler and the auxiliary fans, leading to “Heat Soak” where the car loses power after 15–20 minutes of spirited driving
