Airbox / Housings
This rubber strap set (2 pcs) is manufactured to original Porsche specifications to secure the air cleaner housing on Porsche 911 / 911 S / Carrera 3.0 / 911 SC (1974 – 1983). Each strap replicates the factory design, providing precise elasticity, correct length, and durable retention for a stable, vibration-free air cleaner assembly.
Fits:
Porsche 911 / 911 S 1974–1977
Porsche Carrera 3.0 1976–1977
Porsche 911 SC 1978–1983
Diagram ref no 15
These straps firmly hold the air filter housing in place, ensuring proper sealing and alignment. By preventing vibration and air leaks, they help maintain consistent engine airflow, filtration efficiency, and overall performance.
• Includes: 2 × Rubber straps for air cleaner housing
• Position: Engine compartment – air cleaner housing mount
Over time, the original straps can crack, stretch, or lose tension due to constant heat and aging. Worn straps may allow the air box to rattle or leak unfiltered air, reducing efficiency and risking engine wear. Replacing both straps together ensures equal tension and reliable, factory-level security.

This rubber strap is a reproduction of the original Porsche air cleaner mounting strap, used to secure the air filter housing on classic Porsche 911, 911 S, Carrera 3.0, and 911 SC models (1974–1983). Manufactured to factory-correct dimensions and elasticity, it provides the same secure hold, flexibility, and durability as the genuine part.
Sold each, 2 required per vehicle.
Fits:
Porsche 911 / 911 S 1974–1977
Porsche Carrera 3.0 1976–1977
Porsche 911 SC 1978–1983

The rubber strap keeps the air cleaner assembly firmly in place, preventing movement and vibration under engine load. It ensures the air filter housing remains properly sealed to prevent unfiltered air intake and helps maintain optimal engine performance and reliability.
• Position: Engine compartment – air cleaner housing mount
Original rubber straps harden, stretch, or crack over time due to heat exposure and age. A worn or broken strap can cause the air cleaner to loosen or rattle, risking air leaks and reduced engine efficiency. Replacing it with an replacement strap restores a firm, factory-tight fit and ensures continued engine protection and smooth operation.

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.
