Ferrari Purosangue Diffuser Rear Bumper 958047

the part number 958047 refers to the Rear Bumper Diffuser for the Ferrari Purosangue. This component is a massive, aerodynamically functional piece that forms the lower section of the rear fascia, housing the quad exhaust tips and the rear fog/reverse lighting.

1. Technical Identification

Part Number: 958047
Vehicle Application: Ferrari Purosangue (2023–Present).
Materials: * Standard: Usually a high-grade thermoplastic or matte-painted composite.
- Optional: Often replaced or overlaid by Carbon Fiber versions in higher-spec “Ad Personam” builds.
Function: The diffuser is designed to manage the airflow underneath the car, creating a low-pressure zone to increase downforce at high speeds. It also features integrated mounting points for the parking sensors and the rear camera system.

2. 2026 Market Pricing (Estimated USD)

As the Purosangue is a flagship V12 model, the cost of the rear diffuser reflects its size and complexity.

Condition	Source	Estimated Price (2026)
New (Genuine Ferrari)	Authorized Dealer	$6,500 – $8,200
New (Carbon Fiber Version)	Ferrari Genuine Accessory	$12,000 – $15,500
Used (Grade A)	Exotic Salvage	$4,000 – $5,500

3. Key Installation Notes

Sensor Transfer: The diffuser contains the housings for the PDC (Park Distance Control) sensors. When swapping part 958047, you must carefully transfer the sensors and the wiring loom. In 2026, these sensors are extremely sensitive; if they are not seated perfectly, the car will trigger a “Parking System Failure” error.
Exhaust Alignment: The Purosangue’s quad exhaust tips sit deep within the cutouts of this diffuser. If the diffuser is not aligned correctly during installation, the heat from the exhaust can melt the surrounding plastic or carbon fiber.
Underbody Shielding: This part connects directly to the rear underbody panels. You must ensure the “active aero” flaps (if equipped) are not obstructed by the mounting clips of the new diffuser.

4. Aerodynamic Complexity

Part 958047 works in tandem with the “aerodynamic bridge” on the rear of the Purosangue. It is designed to bleed off air pressure from the rear wheel arches. If the diffuser is cracked or improperly installed, it can lead to increased wind noise or a slight reduction in high-speed stability.
