Vents / Grilles
This footwell heating nozzle - also commonly referred to as a heater slide - is a precision-engineered replacement component that matches the original Porsche factory design. Installed within the cabin side rail or footwell heating duct system, it measures approximately 217mm in length and is specifically tailored for 356 B T5 models.
Sold individually, 2 required per vehicle.
Fits:
Porsche 356 B T5
Diagram ref no 34
This component channels heated air from the vehicle’s heating system directly into the cabin footwell. It ensures that warm air is distributed efficiently, improving passenger comfort, especially in colder conditions. Additionally, it helps maintain balanced airflow within the cabin.
Function
• Directs warm air into the footwell area
• Ensures efficient airflow from heater channels to cabin
• Supports even heat distribution inside the vehicle
• Maintains proper operation of the HVAC ducting system
• Helps optimise cabin comfort in cold weather
Over time, original heating nozzles can become worn, blocked, or damaged, restricting airflow and reducing heating efficiency. Replacing this component restores proper air distribution, improves cabin comfort, and ensures the heating system performs as intended - particularly important in classic vehicles where HVAC efficiency is already limited.
When to replace
• Weak or reduced airflow into the footwell
• Visible damage, cracks, or corrosion
• During heating system repairs or restoration
• Uneven or poor cabin heating performance
• Missing or incorrectly fitted original components

Porsche Air Vents & Grilles | Precision Airflow & Interior Comfort Control
Air vents and grilles are essential to your Porsche’s heating, ventilation, and air conditioning (HVAC) system. They control the direction and flow of air within the cabin, ensuring balanced cooling, heating, and defrosting performance. Designed for precision and durability, these components also enhance your vehicle’s interior aesthetics while maintaining optimal airflow efficiency.
At Design911, we supply premium vents and grilles engineered to meet or exceed original design standards. Crafted from durable, heat-resistant materials with exact fitment, our products provide smooth directional control, quiet operation, and a refined cabin appearance.
Whether you’re restoring a classic Porsche interior or replacing worn or damaged components, our vents and grilles deliver dependable airflow management and perfect style integration.
What Do Air Vents & Grilles Do?
Vents and grilles play a key role in your Porsche’s climate control system by distributing air evenly throughout the cabin.
Core Functions:
Direct airflow for heating, cooling, and defrosting. Regulate air volume and direction via adjustable louvers. Provide ventilation to critical cabin zones. Protect HVAC components from debris and dust. Enhance interior styling and comfort.Properly functioning vents ensure consistent cabin temperatures and optimal air distribution from the HVAC system.
Why Do Air Vents & Grilles Fail or Wear Out?
Over time, vents and grilles can degrade due to exposure to sunlight, heat, and repeated use.
Common Causes of Failure Include:
- Broken or loose vent louvers and adjustment mechanisms.
- Fading or cracking from UV exposure.
- Dust or debris accumulation causing restricted airflow.
- Damaged vent tabs or clips affecting fitment.
- Interior wear or impact damage over years of use.
When vents become damaged or misaligned, airflow efficiency drops, leading to uneven heating, cooling, and ventilation performance.
Why Replace Your Porsche Air Vents & Grilles?
Replacing worn vents and grilles restores proper airflow direction and ensures a refreshed, premium cabin appearance. Upgraded or restored components improve climate control precision and prevent airflow loss.
Key Benefits:
- Restores accurate airflow control and distribution.
- Prevents air leaks and blocked vent paths.
- Enhances interior look and comfort.
- Improves HVAC system efficiency and responsiveness.
- Compatible with Porsche 911, Boxster, Cayman, Panamera, Macan, Cayenne, and classic models.
- Perfect for restorations, detailing, and climate system maintenance.
For best results, inspect duct seals and connections during
replacement to ensure full air pressure restoration and quiet operation.
