Product Information
Complete air filter system retro fit kit GT4 RS style, Carbon Fibre. 


Fits:
Porsche 981 Cayman / Cayman S - 2013 to 2016 
Porsche 981 Cayman GT4  - 2016
Porsche 718 Cayman GTS / GT4 - 2017 onwards (6 cylinder models)

The intake system for the 6-cylinder 981 and 982 (718) Porsche Caymans is uniquely crafted from prepreg carbon fiber and infused carbon fiber, both cured in an autoclave. This is the only complete intake system available on the market for these Porsche models.

Featuring built-in snorkels, the system facilitates air ducting from a higher point on the side of the car, resulting in lower intake temperatures, more laminar airflow, reduced turbulence, and maximized performance. Extensive testing and development have ensured this intake system delivers optimal results for your Porsche Cayman.

The system is fully reversible and requires no cutting or modification of original parts, except for trimming the plastic cover under the roll hoop. It also enhances the driving experience with a great induction noise from the engine, located right behind the driver's ears. Designed to maintain an OEM+ look, the system boasts a stunning carbon fiber appearance in various finishes, all providing excellent UV protection.

Additionally, the existing lower side ducts will now function as auxiliary air-cooling channels for the engine, similar to the GT4 RS.

Installation Process
The installation process of the RS Style Carbon Intake is straightforward and can be undertaken by professional technicians or experienced car enthusiasts. It includes a detailed installation video to ensure a smooth and hassle-free process. Following the provided guidelines carefully is essential to achieve the best results.

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.
