Air Induction Kits

GruppeM RAM AIR SYSTEMS epitomize the GruppeM philosophy of attention to detail. By replacing the factory air handling systems, increased airflow streams into the combustion chamber.

On the GruppeM intake for 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 K&N air filter materials prevent contaminants from interfering with proper engine function.

What This Product Does

This system provides the hardware needed to connect an individual throttle body installation to large-volume GT3 intake manifolds. Its resonance flap assembly, intake T-piece, filter and vacuum-control components form an integrated intake arrangement for a custom classic 911 engine build.

Functions

• Connects compatible GT3 intake manifolds to an existing individual throttle body system
• Supports operation of the supplied intake resonance flap
• Provides filtered air through the included K&N air filter
• Supplies the vacuum hardware, hoses and fittings required for flap control
• Allows a choice of PA12 nylon or machined aluminium intake T-piece

Technical Details

• GT3 manifold port diameter: 49mm
• Reference comparison stated by the manufacturer: standard 964 manifold 43mm and 3.2 manifold 39mm
• Base nylon T-piece manufactured from automotive-grade PA12
• CNC-machined resonance flap assembly uses sealed roller bearings
• AMS machined components have a black anodised finish
• Custom adapter option comprises six machined aluminium adapters made to supplied ITB dimensions

Kit Contents and Options

The base kit contains the intake T-piece, K&N air filter, CNC-machined resonance flap assembly, four resonance-flap and throttle sleeves, six intake-adapter sleeves, hose clamps, vacuum canister, solenoid, check valve, connector kit, mounting hardware, vacuum hoses, fasteners and fittings.

Nylon T-piece configurations are offered with or without a pair of AMS GT3 intake manifolds. Aluminium T-piece configurations use a machined filter adapter matching the resonance flap assembly and are also offered with or without manifolds.

The ITB-to-GT3 adapter set adds six custom aluminium adapters. These require accurate measurements from the individual throttle body installation and are only supplied with the applicable base-kit options; the adapter set is not offered separately.

Why This Kit May Be Required

This kit is intended for engine builds where an existing ITB system is to be combined with GT3-style intake plenums and a controlled resonance flap. Correct measurements, mechanical installation and engine-specific calibration remain essential because throttle body dimensions and modified engine specifications can differ between applications.

FAQs

• Are intake manifolds included?
  Manifold inclusion depends on the selected configuration. Options are available both with and without a pair of AMS GT3 intake manifolds.
• What T-piece materials are offered?
  The system can be configured with an automotive-grade PA12 nylon T-piece or a machined aluminium T-piece and filter adapter.
• Are adapters supplied for the existing throttle bodies?
  Six custom aluminium adapters can be specified, but accurate dimensions from the throttle body kit must be provided for their design and manufacture.
• Can the custom adapter set be ordered separately?
  No. The manufacturer specifies that the adapter set is only supplied with the applicable base-kit configurations.
• Does installation require engine calibration?
  Engine management and fuelling should be configured for the individual engine, throttle bodies and intake arrangement by a suitably experienced specialist.

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.

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.  

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

Introducing the Silverlake Porsche 911 GT3-style intake manifolds, designed for both ITB (Individual Throttle Bodies) or DBW (Drive-By-Wire) applications. These manifolds are compatible with air-cooled and water-cooled Porsche engines, offering a lightweight and high-performance alternative to the OEM cast aluminum version.

Available in two advanced materials: temperature-cured carbon fiber prepreg or glass fiber-reinforced thermoplastic, each plenum weighs just 825 grams (1.8 lbs), significantly lighter than the 2400 grams (5.3 lbs) of the stock aluminum version. This results in a total weight reduction of 3.15 kg (7 lbs) per pair — a 65% savings compared to the original.

Engineered and flow bench tested to ensure optimal airflow volume, the carbon fiber version features a matte finish, while the thermoplastic model comes painted in black, with the option for custom repainting. Both versions are free of logos, providing a clean, personalized look.

The kit includes two manifolds/plenums, the high-temperature silicone couplers are available separately.

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.
