Lamborghini Aventador LP700 Bumper CARBON Diffuser 470807539C

In 2026, the part number 470807539C refers to the Rear Bumper Carbon Fiber Diffuser specifically for the Lamborghini Aventador LP700-4.

This is the central aerodynamic element at the bottom of the rear bumper. While the LP700-4 originally came with a matte black plastic diffuser as standard, this “C” revision part is the Genuine Carbon Fiber upgrade from the Lamborghini Accessori Originali catalog.

1. Technical Identification

• Part Number: 470807539C

• Application: Aventador LP700-4 (Coupe and Roadster).

• Material: 2×2 Twill Weave Carbon Fiber (Gloss or Matte finish, though “C” typically denotes the standard gloss finish).

• Compatibility Note: This part is designed for the original LP700-4 bumper. It will not fit the Aventador S (LP740-4) or the SV/SVJ without the corresponding bumper assembly, as the exhaust exit and fin geometry are completely different on those models.

2. 2026 Market Pricing (Estimated USD)

Carbon fiber components for the original Aventador have seen a price increase as Lamborghini transitions these items to their “Classic” or heritage parts supply.

3. Installation & Considerations

• Mounting Points: The diffuser is secured using a series of Torx bolts and heavy-duty clips. Accessing the top mounting points usually requires removing the entire rear bumper assembly.

• Heat Shielding: Because the Aventador’s massive V12 exhaust sits directly above this part, the 470807539C includes integrated thermal shielding on the inner side. If buying a used unit, ensure this shielding is not peeling or missing, as the heat can delaminate the carbon fiber resin.

• PDC Sensors: The rear parking sensors are housed in the bumper just above the diffuser, but the wiring harness often clips onto the diffuser’s internal frame. Be careful not to pinch these wires during reinstallation.

4. Why the “C” Revision?

The “C” suffix in this part number often indicates an improved clear-coat resin used by Lamborghini to prevent the “yellowing” or “milking” that affected very early (2012–2013) carbon fiber parts due to UV and heat exposure.
