The Genuine Porsche Air Exhaust Duct (Part Numbers: 99150352390 and 99150352490) is an original equipment aerodynamic bodywork component designed for the Porsche 911 (991.1) GT3 RS.

• Porsche 991.1 GT3 RS 4.0L (500 Bhp) 2015-16  

Positioned within the front wing ventilation system, these air exhaust ducts help manage airflow around the front wheel arches by providing a controlled route for air to escape through the upper wing outlets.

The ducts are available in separate left-hand and right-hand configurations:

99150352390 – Left-Hand Air Exhaust Duct

99150352490 – Right-Hand Air Exhaust Duct

The Porsche 991.1 GT3 RS features distinctive front wing ventilation outlets, which form part of its aerodynamically developed body design.

As the vehicle moves, air enters and circulates within the front wheel arch areas. Pressure can build inside the wheel housings, particularly at higher speeds.

The air exhaust duct works with the front wing ventilation arrangement to direct this air towards the external outlets, helping reduce unwanted pressure accumulation and supporting the vehicle's intended aerodynamic performance.

Manufactured to Porsche's original equipment specifications, these ducts are shaped to fit their corresponding wing positions and work with the surrounding body panels and ventilation components.

Their design also helps maintain the distinctive appearance of the GT3 RS front wing outlets.

Although the ducts do not contain moving mechanical parts, they can become damaged through road debris, minor impacts, incorrect removal, previous accident repairs or deterioration of mounting points.

A cracked, distorted or incorrectly fitted duct may interfere with the intended airflow path or leave the visible ventilation assembly insecure.

Replacing a damaged duct with a Genuine Porsche component helps restore the factory-designed front wing ventilation arrangement, maintain correct component alignment and preserve the original appearance of the vehicle.

Ideal for bodywork repairs, aerodynamic component replacement, accident restoration and Porsche 991.1 GT3 RS maintenance, these Genuine Porsche Air Exhaust Ducts provide original equipment replacement options for their respective installation positions.

What This Product Does:
The air exhaust duct is part of the Porsche 991.1 GT3 RS front wing ventilation system.

Its primary function is to help channel air from the front wheel housing towards the ventilation outlets located on the upper surfaces of the front wings.

During driving, airflow around the rotating front wheels can create pressure within the wheel arch areas.

The GT3 RS front wing ventilation design provides a route for some of this air to escape, helping to manage pressure and airflow around the front axle.

The duct forms part of this arrangement, supporting the intended movement of air through the ventilation opening.

Its main functions include:

• Directing wheel arch airflow: Helps guide air from the front wheel housing towards the external wing outlet.
• Managing wheel housing pressure: Supports the release of air that can accumulate around the rotating front wheels.
• Supporting aerodynamic efficiency: Forms part of the factory-designed front wing ventilation system.
• Supporting front axle aerodynamic performance: Helps maintain the airflow conditions intended by Porsche's GT3 RS bodywork design.
• Maintaining correct ventilation routing: Provides the shaped air passage required by the corresponding wing assembly.
• Supporting the external outlet assembly: Works with the surrounding front wing and ventilation components.
• Maintaining correct component alignment: Helps preserve the original positioning of the ventilation arrangement.
• Preserving bodywork integrity: Restores the intended fit of the duct within the front wing structure.
• Maintaining original vehicle appearance: Supports the distinctive GT3 RS front wing ventilation design.
• Providing a factory-matched replacement: Allows damaged original duct components to be replaced without changing the intended bodywork configuration.

The air exhaust duct is not an engine intake hose, exhaust gas component or cabin ventilation duct.

It is an external aerodynamic bodywork component associated with the front wheel arch and wing ventilation system.

Symptoms Of Wear Or Failure:
Unlike a mechanical or electrical component, the air exhaust duct does not normally produce fault codes or engine performance symptoms.

Failure is more likely to involve physical damage, incorrect positioning or deterioration of its mounting arrangement.

Common signs of a damaged or defective air exhaust duct include:

• Visible cracks: Impact damage or excessive stress may cause cracking in the duct body.
• Broken mounting points: Damaged attachment locations may prevent the duct from being secured correctly.
• Loose duct assembly: Worn or broken retaining components may allow unwanted movement.
• Rattling noises: An insecure duct may produce vibration or rattling during driving.
• Poor panel alignment: A distorted duct may interfere with the correct fit of the surrounding ventilation components.
• Damaged air outlet opening: Physical damage may affect the shape or condition of the ventilation passage.
• Restricted airflow: Debris, deformation or obstruction may interfere with the intended air exit route.
• Visible gaps: Incorrect positioning may leave unwanted gaps around the outlet assembly.
• Missing retaining hardware: Absent or damaged fasteners may prevent secure installation.
• Broken plastic sections: Impact or incorrect removal may fracture parts of the duct.
• Scraping or contact marks: A loose component may rub against adjacent bodywork or wheel housing parts.
• Road debris damage: Stones and debris may damage exposed areas of the ventilation system.
• Accident-related deformation: Front wing or wheel arch damage may affect duct positioning.
• Previous incorrect repair: Improper assembly may leave the duct misaligned or inadequately secured.
• Missing duct sections: An incomplete ventilation arrangement may no longer function as originally intended.

A cracked, distorted or incorrectly mounted duct may interfere with the intended airflow path or compromise the fit of adjacent bodywork components.

Because the GT3 RS front wing ventilation system is part of Porsche's aerodynamic design, damaged components should be repaired using the correct specification parts.

The line carries vacuum through the vehicle to the brake servo / brake booster. This vacuum assistance reduces the amount of pedal effort required from the driver when applying the brakes, allowing the braking system to deliver strong and progressive braking with a normal pedal feel.

Because the line must remain airtight, cracks, damaged connections or leaks can reduce the amount of vacuum available to the brake booster. This can lead to a noticeably harder brake pedal and reduced power assistance, even though the hydraulic brakes may still operate mechanically.

What This Product Does:

• Carries vacuum to the brake booster.
• Supports power-assisted brake operation.
• Reduces the amount of pedal force required during braking.
• Helps maintain a consistent and predictable brake pedal feel.
• Forms part of the sealed brake-servo vacuum circuit.
• Transfers vacuum through the central/underbody section of the vehicle.
• Helps the brake booster provide additional braking assistance.
• Replaces a cracked, damaged, leaking or deteriorated original vacuum line.
• Restores vacuum-system integrity when a leak has been identified.

Porsche parts diagrams list 99735557101 directly within the brake-line and underbody vacuum system, identifying it as the central vacuum line in the brake system.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Brake pedal becoming unusually hard.
• Increased pedal effort required to slow the vehicle.
• Reduced brake-servo assistance.
• Brakes feeling normal initially but becoming harder after repeated pedal applications.
• Hissing noise when the brake pedal is pressed.
• Hissing or air-leak noise from underneath the vehicle.
• Vacuum-related noises after the engine is switched off.
• Inconsistent brake pedal assistance.
• Cracks or splits in the vacuum line.
• Damaged or loose line connections.
• Physical damage caused by road debris or underbody impact.
• Deteriorated seals or connecting pieces.
• Brake booster failing to retain vacuum.
• Vacuum-system faults found during diagnostic testing.

A hard brake pedal does not automatically mean the vacuum line itself has failed. The brake booster, vacuum pump, non-return valve, connections and other vacuum hoses should also be checked during diagnosis.

Why Replacement Matters:
The brake booster relies on vacuum to provide power assistance.

If the vacuum line develops a leak, the booster may receive insufficient vacuum to assist braking correctly. The hydraulic braking system can still apply the brakes, but substantially greater pedal force may be required.

Replacing a leaking or damaged vacuum line helps restore:

• Correct brake booster vacuum.
• Normal brake pedal effort.
• Consistent braking assistance.
• Predictable brake pedal feel.
