Porsche 928 Leather Dashboard Ventilation Grille - Windshield Defog Vent Kit
Restore Proper Windshield Defogging and Interior Finish
The Porsche 928 leather dashboard is equipped with dedicated
ventilation grilles that direct airflow toward the windscreen to prevent
fogging and maintain clear visibility. These defog vents are essential
components of the climate control system and interior trim.
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
Diagram Ref No 2
Originally supplied by Porsche, this part is now NLA (No Longer Available) and often becomes brittle, cracked or damaged over time. This high-quality reproduction is identical in appearance and function to the original and is manufactured from similar durable plastic material.
The ventilation grille sits within the leather dashboard and allows heated or ambient air to flow directly onto the inside of the windshield.
Its function includes:
- Directing airflow to prevent windshield fogging
- Assisting with defrosting in cold conditions
- Supporting overall climate control efficiency
- Maintaining the clean factory appearance of the dashboard
Without a properly functioning defog vent grille, airflow can be restricted, reducing visibility and affecting interior aesthetics.
Why Porsche 928 Defog Vent Grilles Fail
After decades of heat exposure and UV radiation, original
928 dashboard vents commonly suffer from:
- Plastic cracking or splitting
- Warping due to sun exposure
- Brittleness from ageing materials
- Damage during dashboard reupholstery
- Broken mounting tabs
When restoring or reupholstering a leather dashboard, the original vent grille often cannot be reused due to its fragile condition.
Why You Should Upgrade
You should consider replacing your Porsche 928 dashboard
defog vent grille if:
- You are reupholstering or restoring the dashboard
- The original vent is cracked or faded
- Mounting points are broken
- Airflow to the windshield is reduced
- You want to restore factory-correct interior appearance
Replacing both left and right vent grilles is recommended for consistent fitment, colour matching and symmetrical interior presentation.
This reproduction part ensures:
- Correct airflow performance
- Clean integration into leather dashboards
- OEM-style fit and finish
- Long-term durability compared to aged originals
Perfect for concours restorations, full interior refurbishments or preventative replacement.
Key Benefits at a Glance
- Direct replacement for NLA Porsche part
- Identical appearance to original design
- Manufactured from durable plastic material
- Restores windshield defog airflow
- Suitable for leather dashboard 928 models
- Recommended to replace both sides for best results
- Ideal for restoration and reupholstery projects

Dashboard parts play a crucial role in your Porsche’s interior design, functionality, and driver experience. From switches, vents, and trims to instrument housings and brackets, these components ensure your dashboard remains solid, stylish, and fully functional.
