Product Information
Product Information
This a replica of the Porsche Germany RS lightweight factory heat duct that was used on all 3.6 liter special RS lightweight rare cars.

The Porsche part is ugly roto-formed cheap plastic with parting lines whereas accurate replica is carbon fiber.

Saves 8 to 9lbs about 4Kg from the rear of all 964's and 993's. Will not work on C2 Turbos/965 cars.

Replaces blower motor assembly and ductwork and still allows plenty of heat just like the factory RS part.

Ultra cool clear coated real carbon fiber tube that really cleans up engine bay and makes working on engine easy.

Simple do it yourself 20 minute installation that gives you the RS style engine look.

Please Note:

All late model 993's 1996-98 (Varioram engines) require the 964 early type fan air guide shroud (as shown on exploded image)
Can be added below

Fits:

Porsche 964 C2/C4 1989-1994
Porsche 993 C2/C4 1994-1997

Rennline RS Carbon Fiber heater duct.

Fits:
Porsche 964 / 993 1989 - 1998 EXCEPT 95's*.
993's require the 964 fan shroud part # 964.106.403.02 .
Many people are using these on 95's but fitment at the base is poor, and we do not recommend installation on this model year.

Rennline’s blower motor bypass pipe is a carbon fiber replica of the factory installed unit found on the lightweight 3.6 RS race cars. This pipe allows you to save 9 pounds from the removal of the factory blower motor assembly, but still have a functioning heater system in your car. Manufactured from ultra strong, lightweight carbon fiber and comes equipped with the aluminium fitting for the distributor breather tube.

Note: Pictures may not show actual product.

About Heater hoses & pipes

Porsche Heater Hoses & Pipes | Reliable Coolant Flow & Cabin Heating Efficiency

Heater hoses and pipes are essential components in your Porsche’s heating and cooling system. They carry heated coolant from the engine to the heater core, enabling warm air circulation throughout the cabin. Without properly functioning hoses and pipes, the heating system cannot deliver consistent temperature control or maintain efficient engine cooling.

At Design911, we supply premium heater hoses and coolant pipes that meet or exceed original engineering standards. Constructed from high-quality rubber, aluminium, or reinforced composite materials, these components ensure leak-free performance, excellent heat resistance, and long-term durability.

Whether you’re restoring a classic 911 or maintaining a modern Porsche with advanced climate control systems, our heater hoses and pipes provide the precision, fitment, and performance required for dependable heating and cooling.

What Do Heater Hoses & Pipes Do?

Heater hoses and pipes form the circulation path that carries hot coolant from the engine to the heater core, allowing the HVAC system to provide warm air inside the cabin.

Core Functions:

  • Transfer heated coolant to the heater core for cabin warming.
  • Maintain proper coolant flow between engine and heating system.
  • Regulate temperature and prevent air pockets in the system.
  • Ensure efficient heat exchange for passenger comfort.
  • Protect against coolant loss and overheating.

A properly functioning set of hoses and pipes is critical for both engine cooling performance and interior heating efficiency.

Why Do Heater Hoses & Pipes Fail or Degrade?

These components endure constant heat, pressure, and vibration. Over time, material fatigue and corrosion can lead to leaks or blockages.

Common Causes of Failure Include:

  • Age-related cracking, swelling, or brittleness of rubber hoses.
  • Corrosion or pinhole leaks in metal pipes.
  • Coolant contamination or chemical degradation.
  • Loose or damaged hose clamps causing leaks.
  • Blockages from scale or debris restricting coolant flow.

When heater hoses or pipes fail, symptoms include coolant leaks, weak cabin heat, overheating, or a sweet smell of antifreeze inside the cabin.

Why Replace Your Porsche Heater Hoses & Pipes?

Replacing worn or damaged heater hoses and pipes restores proper coolant circulation, prevents leaks, and ensures stable heating and engine temperature control.

Key Benefits:

  • Restores efficient coolant flow and cabin heating performance.
  • Prevents leaks, overheating, and engine damage.
  • Improves reliability and system pressure integrity.
  • Resistant to heat, pressure, and corrosion for long lifespan.
  • Direct-fit replacements for Porsche 911, Cayman, Boxster, Panamera, Macan, and Cayenne models.
  • Ideal for maintenance, restorations, or performance upgrades.

It’s recommended to replace heater hoses and clamps during coolant service intervals to maintain maximum system reliability.

Highlights

  • Precision-engineered Porsche heater hoses and coolant pipes.
  • Constructed from high-quality, heat-resistant materials.
  • Direct-fit replacements for Porsche models old and new.
  • Designed for long-term resistance to pressure and corrosion.
  • Ensures reliable heating and engine cooling performance.
  • Ideal for restoration, servicing, and preventative maintenance.
