This is a custom 3D-printed cold-air intake duct designed specifically for the Alfa Romeo 159, routing fresh air straight through the headlight area for optimal airflow to the intake system.
The duct follows the natural curve of the headlight lens on the front side, and at the rear it aligns perfectly with the OEM bulb-cap opening, allowing full, direct airflow into the airbox or aftermarket filter.

Installation requires cutting/modifying the original headlight lens.
This product is intended for performance applications where maximum airflow is desired.

Product Details:

• Part: Headlight Cold Air Intake Duct (headlight not included)
• Compatibility: Alfa Romeo 159 (All engines / 2005–2011)
• Design:
  • Front section follows the OEM lens curvature
  • Rear outlet aligns precisely with the OEM bulb-cap location
• Fitment:
  • Requires cutting the headlight lens
  • Rear fits through the factory bulb-cap opening
• Material: ABS plastic (automotive-grade, heat-resistant)

Rear Cap Options:

This duct is compatible with:
• The original OEM headlight bulb cap — if you want to keep the duct closed when not in use
• Our custom open-flow performance cap — maximizing airflow straight to the intake or air filter

Material – ABS Plastic:

ABS is well-suited for performance intake components due to:
• high rigidity and impact resistance
• stability under engine-bay heat
• resistance to vibration and road conditions
• excellent paint/primer adhesion (optional)

Ideal for aerodynamic and airflow-focused components.

Surface Finish Note:

3D-printed ABS may show fine layer lines.
Light sanding, primer, and paint can achieve an OEM-like appearance.
Cosmetic finishing is optional and not required for functionality.

Production Quality:

Each duct is based on accurate 3D modeling of the Alfa Romeo 159 headlight geometry, printed with calibrated settings to ensure:
• perfect fit onto the headlight curvature
• correct alignment with rear bulb-cap opening
• reliable structural rigidity
• smooth internal air channel for improved flow

Important Fitment Information:

• Headlight lens must be cut to install this cold-air intake duct
• This part is intended for performance, off-road, or motorsport use
• Ensure local regulations allow intake/headlight modifications
