Heating Pipe This a replica of the Porsche Germany RS lightweight factory heat duct that was used on all 3.6 litre 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.
Air induction pipe: This a replica of the Porsche Germany RS lightweight factory air duct that was used on all 3.6 liter special RS lightweight race cars. The air duct is directed up towards the boot lid where air is forces into the air duct and then into the air box. Simple do it yourself installation that gives you the RS style engine look.

Carbon Fibre Air Box Intake System - Non Varioram Cars
Bring more character from the air-cooled flat-six in your Porsche 993 with the Rennline Carbon Fibre Air Box Intake System.
Developed as a functional and visual upgrade
for the original intake system, the Rennline air box is designed to improve
airflow, enhance induction sound and replace ageing factory plastic components
with premium motorsport-inspired carbon fibre.
Fits:
- Porsche 993 (911) C2 1994-95
- Porsche 993 (911) C4 1994-95
- Porsche 993 (911) C2S 1994-95
- Porsche 993 (911) C4S 1994-95
The Porsche 993 represents the final evolution of the air-cooled 911, and its flat-six engine is a major part of the driving experience. Rennline's intake system allows more of that character to be heard, delivering a more engaging induction note while giving the engine bay a cleaner, more purposeful appearance.
Carbon Fibre Intake Upgrade
The Rennline air box replaces the decades-old factory plastic intake components with lightweight carbon fibre construction. Its exposed carbon weave provides a premium finish that works particularly well in restored, modified and performance-focused Porsche 993 engine bays.
Unlike a purely cosmetic carbon fibre replacement, this system has been developed as a functional intake upgrade, with increased airflow and a more pronounced induction sound helping to make the naturally aspirated flat-six feel more engaging from behind the wheel.
What Does the Rennline Carbon Fibre Air Box Do?
The air box forms an important part of the engine's intake system, directing filtered air towards the engine while providing a controlled path for airflow.
Rennline's redesigned carbon fibre system is engineered to improve airflow compared with the ageing factory arrangement while allowing more of the characteristic flat-six induction sound to reach the driver.
The result is a modification that enhances the driving experience without compromising the classic character that makes the Porsche 993 so distinctive.
Why Upgrade the Original Porsche 993 Air Box?
Original Porsche 993 intake components are now decades old. Repeated heat cycles, vibration and general ageing can leave plastic components faded, brittle or cosmetically tired.
Replacing the original air box with the
Rennline carbon fibre system provides an opportunity to refresh the intake
while introducing several improvements:
- Increased intake airflow
- Enhanced flat-six induction sound
- Lightweight carbon fibre construction
- Reduced weight compared with ageing factory components
- Improved engine bay appearance
- Premium motorsport-inspired carbon weave
- More engaging throttle and induction character
- Purpose-designed for the Porsche 993
Enhanced Air-Cooled Flat-Six Sound
One of the principal attractions of this intake upgrade is sound.
The naturally aspirated air-cooled flat-six is central to the character of the Porsche 993, and the Rennline intake allows more of its induction note to be heard as engine speed and throttle opening increase.
This creates a stronger connection between throttle input and engine response, particularly during enthusiastic driving, without changing the fundamental character of the 993.
Premium Carbon Fibre Construction
Carbon fibre provides a natural choice for a performance-focused intake system, combining low weight with a distinctive motorsport appearance.
The exposed weave transforms an area normally dominated by black factory plastic and makes the air box a prominent feature within the 993 engine bay. It pairs particularly well with other carbon fibre engine components and performance upgrades.
Porsche 993 Carbon Fibre Intake Upgrades
Carbon fibre intake systems are a popular upgrade for owners looking to combine performance-focused engineering with improved engine bay presentation.
For the Porsche 993, where many original plastic components are now several decades old, a high-quality carbon fibre air box provides an effective way to modernise the intake while respecting the character of the final air-cooled 911 generation.
The Rennline system is particularly suited to owners searching for a Porsche 993 carbon fibre air box, 993 induction upgrade or lightweight intake system that provides both functional and visual improvements.
Benefits of Upgrading
Installing the Rennline Carbon Fibre Air Box
can provide:
- Improved intake airflow
- More engaging induction sound
- Reduced intake component weight
- Replacement of ageing factory plastics
- Premium carbon fibre engine bay appearance
- Enhanced flat-six driving experience
- Motorsport-inspired styling
- A high-quality upgrade for restored or modified Porsche 993 models

The Porsche 993 1996-98 WITH STANDARD REAR SPOILER , the factory ductwork is replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed -- high-efficiency, high-flow air filter materials prevent contaminants from interfering with proper engine function.

Cooler air = MORE POWER + 8-10BHP.
Cone filters have superior air flow characteristics as compared to flat panel filters. The cone filter better structures the air as it enters through the filter and the additional intake length and shape of this system further increases air flow for smoother straighter more formed air.

BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
DESIGN AND MATERIALS
Qualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.

- Distributor ventilation connection (A)
- Rubber Grommet (B)
- White Grommet connector (C)
- Hose (D)
HOW TO FIT: Firstly prise of the oval plate arrowed on the distributor with a screwdriver. Then remove the large black air guide pipe as we need to drill a hole in it at the green dot. The pipe removes by loosening jubilee clips at top and bottom. You will also need to remove two sensor connectors on the pipe. I also removed the two sensors near the distributor so that I had easy access to the plate. Drill at 18mm hole in the pipe, 40mm to the right of the tail light ventilation nipple. Deburr the hole and remove all shavings. Install the rubber grommet (B) into the hole and install the white connector (C) into the grommet.Install the distributor connector (A) into the hole in the distributor where the plate was. Finally refit the air pipe and connect back up all the sensors. Install the hose (D) onto the new distributor and air pipe nipples and route

On the GruppeM intake for the Porsche 993 1996-98 WITH RS REAR SPOILER , the factory ductwork is replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed -- high-efficiency, high-flow K&N air filter materials prevent contaminants from interfering with proper engine function.

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.
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
Due to manufacturing tolerances and the nature of composite materials, minor trimming of excess material may be required during installation to ensure optimal fitment.

Engine Tuning Air Induction Kits – Unlock Your Porsche’s True Breathing Potential
An air induction kit is one of the most effective tuning upgrades for increasing power and responsiveness in your Porsche. Designed to replace restrictive stock airboxes and piping, these systems improve airflow, reduce intake resistance, and deliver cooler, denser air to the engine. The result is a sharper throttle response, enhanced torque, and a more engaging driving experience.
At Design911, we stock a premium range of performance air induction kits engineered for Porsche models across all generations — from classic 911s to modern Cayman, Boxster, and Taycan models. Manufactured from lightweight, heat-resistant materials with precision-fit components, our high-quality induction systems ensure optimal performance and a refined induction sound that complements your Porsche’s character.
Whether you’re aiming for track-ready performance or improved road dynamics, our air induction kits provide the perfect balance of power, reliability, and sound enhancement.
What Do Air Induction Kits Do?
Air induction kits optimise your Porsche’s intake system by increasing the volume and quality of air reaching the combustion chamber.
Core Functions:
- Increase
airflow efficiency to improve engine breathing and power output.
- Reduce
intake temperatures for denser air and better combustion.
- Enhance
throttle response for sharper, more immediate acceleration.
- Deliver
a sportier induction sound during acceleration.
- Improve fuel efficiency and overall engine performance.
When properly installed, an upgraded induction system can boost both performance and engine responsiveness, making it one of the best value-for-performance modifications available.
Why Do Induction Kits Fail or Require Replacement?
Like all high-performance components, air induction kits and filters are subject to environmental wear and heat exposure over time.
Common Causes of Failure Include:
- Clogged
or damaged filters reducing airflow and power.
- Cracked
intake pipes causing air leaks and inaccurate sensor readings.
- Heat
soak from poor insulation or worn heat shields.
- Contaminant
build-up on intake elements and sensors.
- Loose fittings or seals resulting in unmetered air entering the system.
Symptoms of a failing induction system include loss of performance, uneven idle, whistling noises, or increased fuel consumption — all indicators that maintenance or replacement is needed.
