Designed exclusively for Porsche 964 Coupe models, this kit combines lightweight carbon fibre construction, CNC-machined aluminium components and factory-tinted acrylic side windows to create one of the most distinctive upgrades available for air-cooled Porsche enthusiasts.

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)
  • Gloss clear coat finish
  • Satin clear coat finish

All options utilise the same high-quality carbon construction and differ only in appearance.

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.

Factory Green-Tinted Rear Side Windows

The kit includes replacement rear quarter windows manufactured in factory-style green-tinted acrylic.

Benefits include:

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

Debris Protection Built In

To protect the engine bay and intake pathway, each aluminium bezel includes a factory-installed wire mesh insert.

This helps prevent:

  • Stones Leaves
  • Dirt Road debris
  • Foreign objects

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

Important Compatibility Note

Due to differences in C-pillar geometry, this system is not compatible with:
Porsche 964 Targa

Please confirm vehicle body style before ordering.

About Airbox / Housings

Airboxes & Air Filter Housings – Clean Airflow for Peak Porsche Performance

Airboxes (also known as air filter housings) play a vital role in your Porsche’s intake system by securely housing the air filter and directing clean air into the engine. Designed to optimise airflow while protecting the engine from dust, debris, and contaminants, airboxes ensure maximum performance, fuel efficiency, and reliability under all driving conditions.

At Design911, we offer a comprehensive range of genuine and high-quality airboxes and air filter housings for various Porsche models including the transaxle cars,  911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each housing is precision-engineered for a perfect fit, maintaining proper airflow and filtration for superior engine health and performance.

What Do Airboxes & Air Filter Housings Do?

The airbox is a critical component in your Porsche’s air intake system, performing several important functions:

  • Houses and seals the air filter to ensure only clean, filtered air enters the engine.
  • Optimises airflow for improved throttle response and engine performance.
  • Reduces intake noise while balancing air pressure.
  • Protects the air filter from water, heat, and debris exposure.

Properly functioning air filter housings maintain engine efficiency, reduce wear, and ensure smooth, consistent performance — particularly in high-performance Porsche applications.

Why Do Airboxes & Air Filter Housings Fail?

Over time, airboxes and housings can deteriorate due to exposure to heat, vibration, and environmental conditions. Common causes of failure include:

  • Cracked or warped housings due to heat cycling or impact damage.
  • Broken clips or seals leading to unfiltered air leaks.
  • Moisture or debris intrusion causing filter contamination.
  • Distortion from improper fitment or previous repairs.
  • Aging materials such as brittle plastic or rubber gaskets.

Symptoms of a failing airbox include reduced engine performance, check engine lights, poor throttle response, or visible damage or looseness around the air filter housing.

Why Replace a Damaged Airbox or Housing?

A compromised airbox can allow unfiltered air and debris to enter the engine, leading to premature wear or poor combustion efficiency. Replacing damaged or aged components restores proper sealing, improves airflow, and protects your Porsche’s engine from contamination.

Benefits of replacement include:

  • Restored air filtration and clean airflow.
  • Improved throttle response and power delivery.
  • Prevention of engine damage from dust or debris.
  • Long-term reliability with manufacturer-quality precision.

Our airboxes and housings are constructed from high-strength materials for exceptional durability, precise sealing, and optimal airflow dynamics — engineered to maintain your Porsche’s performance and refinement.
