• Throttle body runner made out of a modified PA12 material and an industrial 3d moulding process
• Seal and original Porsche 997 GT3 Bosch 82mm electronic throttle body
• Vacuum tube with original resonance flap internals. Note the internals come from refurbished original 996 parts.
• Vacuum solenoid and reservoir with mounts as per images
• Rubber boots and clamps
• Vacuum connections, check valve and extra hose
• Original Bosch MAP-T-sensor for 1 bar

Drive by wire inlet conversion kit
Convert the 964/993 induction to Drive by Wire set-up

Fits:
Porsche 964 - 1989 to 1993
Porsche 993 - 1994 to 1998

Product Overview:
Transform your Porsche 964's performance with this sleek and high-tech intake kit designed for Porsche 964/993. This innovation marks a transition from the typical accelerator cable-based throttle to an electronic "drive by wire" throttle body. This advanced change streamlines the intake system by eliminating unnecessary components, resulting in a cleaner engine bay appearance. 

This modification offers a more drivable setup for highly tuned engines while incorporating the precision of a drive by wire (DBW) throttle.

This enhanced drivability is a key feature for a tuned aircooled engine and allows for smooth idle control with a cold as well as a hot engine. It simply makes the engine feel more modern as compared to the old ITB (individual throttle bodies) setups lacking in mid range torque and difficulties with the idle control.

Precision-Engineered Components:

• 82mm Throttle Body with Reinforced Industrial PA12 Manifold
• CNC-Milled Intake Manifold Stacks Crafted from Billet Aluminium
• Included Rubber Boots and Clamps for Easy Installation
• Islandworks Resonance Tube with Valve and Solenoid, Manufactured from the Same PA12 Material
• Integrated Manifold Pressure and Temperature Sensors
• Essential Vacuum Lines for Optimal Performance

Kit Includes
Complete intake with all the parts seen in the image manufactured from modified PA12 using an industrial process. This intake plenum has been optimized to fit on a Porsche 964 or Porsche 993 and includes all vacuum ports for both brake vacuum and to maneuver the resonance flap.

The following parts will be reused from the 964 intake:

• Rubber boots and clamps
• Vacuum reservoir
• The aluminum or plastic plenums
• Resonance flap
• Actuator and shaft

Note: the aluminum or plastic intake plenum is not included in the kit and neither are any of the items specifically listed as excluded above.

What This Product Does

The adapters connect the original intake manifolds to the three-bolt cylinder heads, replacing factory plastic stands that have cracked or otherwise become damaged. Their design supports Adapt Motorsport fuel rails while locating each injector above the original relief in the intake port.

Functions

• Replaces the factory plastic intake manifold stands
• Connects the intake manifolds to three-bolt cylinder heads
• Provides an O-ring seal against the cylinder head
• Supports Adapt Motorsport fuel rails
• Positions the injectors over the original intake-port relief
• Accommodates long, medium or short Bosch-type injectors

Technical Details

• Port options: 42mm and 44mm
• 42mm specification suits standard Porsche 964 intake ports
• 44mm specification suits standard Porsche 993 VRAM and non-VRAM intake ports
• Precision CNC-machined from high-grade aluminium
• Black anodised finish with an O-ring cylinder-head seal
• Compatible with Bosch fuel injectors using 14mm O-ring fittings

Kit Contents

• Four bolts for standard full-length Bosch injectors

The spacer posts are marked so they can be shortened when medium- or short-length injectors are used. The intake manifolds, rubber joiners, injectors and hose clamps are not included.

Why Replacement Matters

Damaged factory plastic stands can compromise the connection and seal between the intake manifolds and cylinder heads. These aluminium adapters provide a replacement interface while also allowing the intake system to use Adapt Motorsport fuel rails and a choice of compatible Bosch injector lengths. Port size must be selected to match the engine and any existing cylinder-head modifications.

FAQs

• Which port size is required for a standard 964 engine? The manufacturer specifies the 41.5mm version for standard Porsche 964 intake ports.
• Which version suits a standard 993 engine? The 43.5mm option is specified for standard Porsche 993 engines with either VRAM or non-VRAM intake systems.
• Which injectors are compatible? The kit accepts Bosch injectors with 14mm O-ring fittings. Its marked posts can be adapted for long, medium or short injector bodies.
• Are the intake manifolds supplied? No. Manifolds, rubber joiners, injectors and hose clamps must be sourced separately.

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.
