Air Induction Kits
Comes complete with thermal insulating manifold gaskets

Fits:
Porsche 911 - 1974 to 1989
Used to fit 964 induction to 911 G-Model engines
Crafted from high-grade aircraft aluminum, our Porsche G-Model to 964 Billet Intake Runner delivers superior performance enhancements. Available in various cylinder head port diameters ranging from 34mm to 42.5mm, with options for standard injector sizes.
Compatibility and Customization:
Tailored specifically to fit Porsche 2.7-3.2L engines, this intake runner enables seamless mounting of a Porsche 964/993 type intake. Unlike the 964/993's 3-bolt attachment, our design utilizes a 2-bolt M8 attachment for cylinder head placement.
Versatile Use and Configurations:
Compatible with standard rails or designed for use with the IslandWorks/Nuke system featuring a direct mount fuel regulator.
Superior Craftsmanship and Finish:
Each runner boasts a natural machined finish, complemented by a base gasket insulator for optimal performance. To ensure that every set of intake runners arrives in style, they are shipped in a personalized color-of-the-day gift box as shown in the images.
Important Note:
This product requires a flat cylinder head seal (included in set) for superior heat insulation, deviating from the conventional seal type.

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.

Direct bolt-on replacement for the factory air box providing increased airflow and power. Made from anodized gold T6061 Aluminum. The gold color mimics the yellow zinc plated OEM hardware that Porsche used in all their air-cooled cars from this era.
The design of this airbox cover was inspired by factory Porsche Cup Cars. After much on-track testing done by Fabspeed's Owner on his 993 RSR, he found that using this open filter design netted the best power results, with more flow and cool intake temps.
SOUND:
The factory Carrera airbox is designed to muffle the induction note of the engine to keep it out of the cabin. This airbox lets all that glorious air cooled flat six induction growl into the cabin.
POWER:
With just this modification we saw a 6whp increase over stock thanks to increased airflow.
FEATURES:
• Fits all late model Porsche 911 Carrera 3.2L vehichles (1984-1989)
• CNC'd T6061 Aluminum construction
• Anodized gold to match the zinc plated hardware in the engine bay
• Adds 6 whp and increases throttle response
• Direct replacement for the OEM front cover lid to improve the induction through an open style intake system
• Compatible with the BMC Air Filter upgrade
• Simple 5 minute DIY installation, no cutting required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Prevents costly airbox explosions, installed with the engine and air box in place. 911 engines since 1973 have had the bad habit of backfiring and blowing a hole an the air box. 911 POP VALVE is installed inside the air box and when a backfire occurs the valve will instantly open and release the backfire pressure. The POP VALVE then automatically closes and the angine continues to run. The POP VALVE has no effect on the performance or fuel mileage.

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.
Why Upgrade or Replace with Performance Induction Components?
Replacing worn parts or upgrading to a high-performance induction system ensures consistent airflow, reduced restriction, and improved power delivery.
Key Benefits:
- Increases engine power and torque.
- Improves throttle response and drivability.
- Enhances induction sound and character.
