Silverlake

Drive by wire throttle body intake system - Glass Reinforced Thermoplastic. 
Throttle body diameter - 92mm



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

Silverlake Projects' complete Drive-by-Wire (DBW) intake system, designed specifically for 964 and 993 engines to be converted to DBW (drive by wire) throttle body.

Our system includes:

• 6 precision-engineered runners crafted from anodized structural aluminum
• 2 anodized fuel rails, also made from structural aluminum for durability and performance
• Dual GT3-style intake manifolds in carbon fiber for weight reduction and strength
• Intake T-tube in glass-reinforced thermoplastic, compatible with a 92mm DBW throttle body
• Resonance flap or resonance flap delete tube in glass-reinforced thermoplastic, complete with a vacuum actuator
• 6 high-temperature silicone couplers for the manifold-to-runner connections
• 4 high-temperature silicone couplers for the manifold-to-T-tube/resonance flap connections
• TMAP sensor for accurate air intake measurements
• Vacuum reservoir for optimized engine performance
• All mounting hardware made from lightweight titanium alloy

Inlet port sizes: 42mm

Weighing just 5.5 kg (12 lbs), our intake system is nearly half the weight of the stock 964 intake, which weighs 11.5 kg (25.3 lbs), offering a substantial weight savings for enhanced performance

Why our system?

• 50% lighter than stock. Lighter than most systems given use of carbon fiber, thermoplastics, and titanium.
• Direct mount of fuel rail to the runner for perfect injector press fit.
• CNC machined PTFE inserts in between the cylinder head and the runner for a superior insulation from the heat from the cylinder heads, especially when in idle and street applications.
• Custom nitrile O-rings in between the runner and the cylinder head, and the intake T and throttle body for a perfect seal
• Silverlake’s precision-molded OEM+ silicone sleeves with a much higher temperature resistance than rubber, offering a perfect fit with the opposing components for better airflow, and an unmatched appearance.
• All mounting fasteners in Tin coated titanium alloy, for reduced weight and un unbeatable appearance
• Your choice between 82mm or 92mm drive by wire throttle bodies, the latter offering 25% more surface for high displacement high performance applications

Silicone coupler sleeve set for GT3 intake manifold plenum to throttle body. 
Sold as a set of 4

Fits:
Porsche 964 - 1989 to 1994 (with GT3 inlet upgrade)
Porsche 993 - 1994 to 1998 (with GT3 inlet upgrade)
Porsche 996 - 1997 to 2005 (with GT3 inlet upgrade)

The original rubber couplers for Porsche 996 and 997 GT3 models have become increasingly costly and hard to source, and many enthusiasts opt to avoid them for high-performance applications like hot rods or track cars due to their limited heat resistance.

Our precision-molded OEM+ silicone sleeves are the perfect direct replacement, offering double the temperature resistance of the original rubber couplers along with an enhanced appearance. These high-quality sleeves are essential for replacing worn-out rubber parts and are ideal for air-cooled hot rods undergoing a modern DBW (Drive-By-Wire) conversion using a GT3 intake plenum.

This set includes four silicone sleeves

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.
