Whether you're building a high-end restomod, creating a track-inspired road car or simply looking for a unique engine bay airflow solution, this system delivers a stunning combination of form and function.

What Does the Rear Window Air Intake Do?

The system draws air through specially supplied factory green-tinted acrylic rear side windows and channels it through a central carbon fibre intake tube.

When installed with the optional rear shelf opening, the intake system:

  • Directs additional airflow towards the engine bay
  • Creates a motorsport-inspired induction pathway
  • Enhances engine compartment ventilation
  • Provides a unique performance appearance
  • Adds distinctive visual character to the vehicle
  • Delivers authentic race-inspired styling

The result is a striking rear cabin feature that instantly differentiates your Porsche from standard models.

Functional or Cosmetic Installation Options

One of the unique advantages of this system is installation flexibility.

Functional Air Intake Installation

Using the supplied cutting template, an opening is created in the rear shelf structure, allowing airflow from the intake system to reach the engine compartment.

Benefits include:

  • Functional engine bay air feed
  • Enhanced airflow routing
  • Authentic motorsport-inspired setup
  • Maximum visual and engineering impact

Non-Cut Cosmetic Installation

The system can also be securely mounted without cutting the rear shelf.

Benefits include:

  • Fully reversible appearance upgrade
  • No structural modifications required
  • Maintains originality
  • Creates the same visual impact

Please note - without cutting the rear shelf, no air is routed into the engine bay and the installation serves as a styling enhancement only.

Premium Carbon Fibre Construction

At the centre of the system is a lightweight carbon fibre intake tube incorporating an integrated debris protection system.

Features include:

  • Lightweight carbon fibre construction
  • Internal black debris mesh installed
  • Motorsport-inspired appearance
  • Excellent rigidity and durability
  • Available in multiple finish options

Carbon Fibre Finish Options

Choose from:

  • Raw visible carbon fibre (no clear coat)

CNC-Machined Aluminium Window Bezels

The intake windows connect to the carbon tube using precision CNC-machined aluminium joints.

Available finishes include:

  • Polished aluminium
  • Matte silver
  • Matte black

Each bezel incorporates an internal wire mesh screen designed to prevent leaves, stones and road debris from entering the intake system.

Benefits include:

  • OE-inspired appearance
  • Lightweight construction
  • Clean integration with the intake system
  • Excellent visual clarity

The mesh is installed during manufacturing and requires no additional assembly.
