Installation Kit: Stainless Steel Cutting fixture and screws.

Front Bumper Air-Outlet Grille Porsche 997 Models.
This air vent can be retro fitted into model 997 bumpers giving the GT3 look.
Fits:
Porsche 997 2005>>
Porsche 987 Boxster 2005>>
Porsche 987 Cayman 2005>>
The front of a GT3 has a look and feel that sets it far apart from any other automobile in its class. The sought after upper air vent screams speed and aggression, but unfortunately it’s only available on a true GT3. Installing one of these vents on a non GT3 bumper can be very problematic, one slip of the saw and your bumper cover is unusable. Rennline's GT3 vent installation kit turns a daunting task into a very simple one. No more tracing, cutting, praying, grinding, and gluing. Just attach the fixture, cut the profile, and mount the OEM vent with the supplied brackets and hardware. It’s truly that simple.
Note: All of these components are designed to work with factory bumpers and vents.
Note: Pictures may not show actual product.

Porsche Exterior Air Ducts & Vents | Aerodynamics, Cooling & Performance
Exterior air ducts and vents are key aerodynamic components that manage airflow around your Porsche’s body, directing cool air to the brakes, engine, and intercoolers while expelling heat from high-temperature zones. These precision-engineered elements not only enhance performance and cooling efficiency but also contribute to the distinctive styling and aerodynamic stability that define every Porsche.
At Design911, we supply a wide range of high-quality replacement and performance exterior air ducts and vents designed specifically for Porsche models — including 911, Cayman, Boxster, Panamera, Taycan, and Macan. Crafted from aerodynamic-grade materials, our ducts and vents deliver superior durability, fitment accuracy, and airflow efficiency to maintain both aesthetics and performance.
Whether you’re restoring a classic, replacing a damaged part, or upgrading for improved airflow, our selection of Porsche air ducts and vents ensures precision fit, reduced drag, and enhanced cooling efficiency.
What Do Exterior Air Ducts & Vents Do?
Exterior air ducts and vents are responsible for guiding airflow efficiently through your Porsche’s bodywork. They provide cooling for vital systems such as brakes, intercoolers, radiators, and the engine bay, while also improving aerodynamic balance.
Core Functions:
- Channels
cool air to brakes, intercoolers, and radiators.
- Reduces
aerodynamic drag for improved performance.
- Expels
hot air from high-temperature zones like the engine bay.
- Enhances
vehicle stability at high speeds.
- Contributes to Porsche’s distinctive design and performance.
Efficient air management is essential for performance Porsches, ensuring consistent cooling under demanding driving conditions and maintaining aerodynamic stability on road or track.
Why Do Exterior Air Ducts & Vents Fail?
Due to their external position, air ducts and vents are exposed to debris, impact damage, and weathering. Over time, they can become cracked, loose, or obstructed — compromising airflow and cooling performance.
Common Causes of Failure Include:
- Impact
damage from road debris or minor collisions.
- UV
degradation and environmental wear.
- Loose fittings or broken clips.
- Corrosion
or discoloration due to age or chemical exposure.
- Blockage from dirt or leaves, reducing airflow.
When damaged or worn, air ducts and vents can cause cooling inefficiencies, increased drag, and diminished aerodynamic performance, making replacement essential for both function and aesthetics.
Why Replace or Upgrade Your Exterior Air Ducts & Vents?
Replacing or upgrading your Porsche’s air ducts ensures optimal airflow management, maintaining performance and cooling efficiency while preserving the car’s signature design.
Key Benefits:
- Restores
effective airflow and component cooling.
- Enhances
aerodynamic efficiency and stability.
- Prevents overheating of brakes, engine, or intercoolers.
- Improves visual appeal and exterior symmetry.
- Manufactured from lightweight, durable materials.
- Precision-fit for Porsche 911, Cayman, Boxster, and more.
Upgrading to performance-grade ducts can also enhance track cooling and reduce aerodynamic lift, improving handling and top-end performance.
Highlights:
- High-quality exterior air ducts and vents for Porsche.
- Improves aerodynamic performance and cooling efficiency.
- Lightweight, impact-resistant construction for long life.
- Direct-fit replacements with perfect alignment and finish.
- Designed for Porsche 911, Cayman, Boxster, and other models.
- Ideal for replacements, restorations, or performance upgrades.
