Product Information
Headlamp Breather Pipe.
The Porsche Headlamp Breather Pipe is a genuine OEM vent tube designed to prevent condensation and moisture build-up inside the headlight housing. Fitted to Porsche 911 (996 models), this pipe allows controlled airflow and pressure equalization, keeping your headlights clear and functioning properly.
Fits LEFT And RIGHT.

Fits:
  • Porsche 996 C2 3.6L 09/01-2005
  • Porsche 996 C4 3.6L 09/01-2005
  • Porsche 996 C4S 3.6L 09/01-2005
  • Porsche 996 TURBO 2000-05
  • Porsche 996 GT2 2001-05
  • Porsche 996 GT3 MKI 1999-02
  • Porsche 996 GT3 MKII 2003>>

What This Product Does:
The tube is a vent / breather tube for the headlamp housing. It allows moisture, condensation and air to escape from the headlamp enclosure so the lens doesn’t fog up, and prevents vacuum or pressure build-up inside the lamp unit.

Symptoms Of A Faulty / Missing / Damaged Vent Tube:

  • Condensation / Fogging inside the headlamp lens, especially after weather changes or car wash.
  • Water accumulation inside the headlight housing (visible water or dripping) leading to corrosion, rust, or water spots.
  • Cloudiness or reduced light output due to moisture affecting reflectors or lenses.
  • Burned / corroded connectors or bulb sockets due to water contact.
  • The headlamp may feel humid inside, smell of damp plastic, or show signs of mildew / moisture staining.

Why Replacement Matters:
  • Preserves headlamp clarity & performance: a clean, dry reflector & lens means correct beam pattern & brightness. Moisture or fog diminish performance and safety.
  • Protects electrical components inside the lamp assembly: bulbs, aim adjusters, connectors are especially vulnerable to water damage.
  • Prevents damage to headlamp internals: moisture can cause corrosion, oxidation, potentially degrading internal seals, screws, and mounting surfaces.
  • Maintains correct optical alignment & beam pattern: trapped moisture can distort or when dried unevenly, affect clarity and aim.
  • Low cost preventive part: replacing a small tube is cheap relative to replacing a full headlamp unit due to water damage.

About Headlamp Parts & Lens

Porsche Headlamp Parts & Lenses | Precision Lighting Components for Safety and Style

Headlamp parts and lenses are critical to both the performance and appearance of your Porsche. Designed to focus and project light accurately, they ensure optimal road illumination and visibility while maintaining your vehicle’s iconic front-end styling. Over time, exposure to UV light, road debris, and weather can degrade headlamp lenses and components — leading to reduced brightness, clouding, or misalignment.

At Design911, we supply high-quality headlamp parts and lenses engineered for exact fitment and performance. Our selection includes replacement lenses, seals, adjusters, mounting brackets, and internal reflectors — available for both classic and modern Porsche models. Choose from standard or upgraded materials, including clear and UV-resistant polycarbonate lenses, for lasting clarity and precision lighting output.

Whether you’re restoring a vintage 911 or maintaining a modern Cayman, our Porsche lighting parts help you keep your headlights shining bright and clear.

What Do Headlamp Parts & Lenses Do?

Headlamp components work together to project, focus, and protect your lighting system for maximum road safety and visibility.

Core Functions:

  • Lenses protect internal bulbs and reflectors while focusing light onto the road.
  • Reflectors optimise light projection for balanced illumination.
  • Seals and covers prevent moisture and dirt ingress.
  • Mounting brackets and adjusters ensure perfect alignment and beam angle.
  • Maintain the vehicle’s signature Porsche look with precision-matched housings.

Without functional headlamp parts, your Porsche’s visibility, safety, and design integrity can all be compromised.

Why Do Headlamp Parts and Lenses Fail or Degrade?

Even with high-end engineering, Porsche headlamp components are exposed to extreme temperatures, UV rays, and vibration, leading to gradual deterioration.

Common Causes of Failure Include:

  • Lens yellowing or clouding from UV exposure.
  • Cracks or chips caused by stone impacts.
  • Moisture ingress due to worn seals or gaskets.
  • Corrosion on reflectors or mounting hardware.
  • Alignment issues caused by damaged brackets or adjusters.
  • Age-related fading reducing light projection.

Aging or damaged headlamp lenses not only reduce visibility but can also fail MOT inspections and diminish your Porsche’s visual appeal.

Why Replace or Upgrade Your Headlamp Parts and Lenses?

Replacing or upgrading your Porsche’s headlamp components restores lighting performance and sharpens your vehicle’s front-end appearance.

Key Benefits:

  • Restores optimal lighting performance and beam focus.
  • Prevents moisture damage and electrical corrosion.
  • Enhances clarity and visibility with new or upgraded lenses.
  • Improves overall safety and road compliance.
  • Available for Porsche 911, Cayman, Boxster, Panamera, Macan, Cayenne other models.
  • Perfect for restorations, MOT preparation, and performance lighting upgrades.

High-quality components from Design911 ensure a flawless fit, long-lasting durability, and performance worthy of Porsche engineering.

Highlights

  • Precision-fit Porsche headlamp lenses and component parts.
  • UV-resistant materials for long-term clarity.
  • Available for classic and modern Porsche models.
  • Includes lenses, seals, adjusters, reflectors, and housings.
  • Designed to restore visibility, function, and style.
  • Ideal for restoration, upgrades, and routine maintenance.
