Redesigned air intake pipe set by OE Match for Porsche 928 models from 1978 to 1991. Supplied as a pair, these replacement pipes connect the front air guides to the air filter housing and replace ageing, damaged or misshapen original ducting. This new design is tighter, neater, and more attractive than
the original design so is well suited for maintenance,
restoration, and a well-kept 928 engine bay.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
- Porsche 928S4 5.0L 1987-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
Diagram ref no 13
What This Product Does
The intake pipes guide outside air towards the air filter housing while maintaining an enclosed route through the front of the engine compartment. Their redesigned construction provides a cleaner layout and is intended to retain its form in place of original pipes that may have softened or distorted after years of exposure to engine-bay heat.
Functions
- Channels incoming air towards the air filter housing
- Replaces split, soft or deformed original intake ducting
- Helps maintain the intended intake route through the engine compartment
- Provides a coordinated replacement for both intake pipes
- Supports maintenance or restoration of the Porsche 928 intake system
Technical Details
- Part type: redesigned air intake pipe set
- Set contents: two intake pipes
- Location: between the front air guides and air filter housing
- Designed for the Porsche 928 intake arrangement
Symptoms of Fault
- Visible splits, tears or surface deterioration
- Pipes that feel unusually soft or no longer hold their original shape
- Partial pipe collapse during hard acceleration
- Poor alignment or sealing at the adjoining intake components
- Hesitation or restricted airflow under higher engine load
- An untidy previous repair or visibly deteriorated ducting
Why Replacement Matters
Original Porsche 928 intake pipes can become brittle, weak or distorted as their material ages. A damaged pipe may no longer remain correctly positioned and can restrict the intake path if it deforms under load. Installing the redesigned pair restores the physical air route and avoids relying on temporary repairs to cracked or weakened pipes. Inspect adjacent connections and retaining hardware during installation so that the complete intake path is properly supported.
FAQs
- Is this supplied as one pipe or a pair?
The product is supplied as a coordinated set of two air intake pipes. - What commonly happens to the original pipes?
Age, heat and movement can leave the original ducting soft, split or deformed. Severely weakened pipes may partially collapse when airflow demand increases. - Why has the design been revised?
The redesigned construction provides a neater replacement for deteriorated original ducting while maintaining the required connection to the air filter housing. - Should other intake parts be inspected?
Yes. Check nearby joints, clamps, seals and the air filter housing for damage or poor alignment while the pipes are being replaced.

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.
