103877 (Flywheel bearing)
For Ferrari 348 owners, the interior fusebox has long been a source of anxiety. The original units are prone to delamination, thermal fatigue, and internal corrosion, leading to intermittent failures or total loss of electrical systems.
To make matters worse, the factory unit is No Longer Available (NLA).
- New Old Stock (NOS): ~€5-7,000 (if you can find one).
- Used/Salvage: ~€3-4,000 (often with the same 30-year-old internal degradation).
The Solution: Modern Engineering, OEM Fit
AS Motorsport has developed a comprehensive solution that ends the cycle of replacing old parts with old parts. Our replacement module is not a reproduction; it is a modern Digital Power Distribution Module (PDM) engineered to fit directly into the original location using factory mounting points and connectors.
No wire cutting. No loom modification. 100% Reversible.
Technical Deep Dive: Why PDM?
Unlike the traditional analog fusebox which relies on physical relays and printed circuit boards that degrade over time, a PDM handles power distribution digitally using solid-state electronics.
- Solid-State Reliability: We have replaced mechanical relays with high-side drivers. There are no moving parts to wear out, stick, or suffer from contact bounce.
- Digital Circuit Control: Power is managed by a microprocessor, ensuring precise voltage delivery to components like windows, fans, and lights.
- Enhanced Circuit Protection: The 348's original design left certain circuits under-protected, a known risk factor for thermal events. Our module integrates additional protection fuses that were not present in the factory design, significantly reducing the risk of wiring harness damage.
- Thermal Management: The PDM generates significantly less heat than the resistive load of a traditional fusebox, protecting the surrounding leather and plastics in the footwell.
Key Features
- Direct Replacement: Bolts into the OEM chassis location.
- Factory Connectivity: Mates perfectly with the original Ferrari wiring harness plugs.
- Zero Maintenance: Solid-state architecture requires no servicing.
- Future-Proof: Designed to handle the electrical loads of the 348 without the voltage drop common in aging factory units.
