Intake manifold set GT3 style. 
Sold as a pair

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.

Application Notes

Not for GT3 RS

Confirm the exact installation before selecting this part for any GT3 RS. Other Porsche installations may be suitable where an oversized 82mm IPD plenum is fitted; upgrade applications require a compatible competition plenum.

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The throttle body meters incoming engine air according to accelerator demand. Its internal butterfly opens or closes to vary the passage through the intake, working with the engine-management system to control airflow.

Functions

• Regulates air entering the intake manifold.
• Varies the intake opening as throttle demand changes.
• Provides the 82mm throttle connection required by a compatible intake installation.

Technical Details

• Brand: OE Match. Supplied reference: 99760511601.
• Throttle diameter: 82mm.
  
  

Symptoms of Fault

Possible reasons for inspection include an unstable or elevated idle, stalling, hesitation, sticking throttle movement, delayed response, throttle-position faults or reduced-power operation. Intake leaks and electrical connection problems can produce similar symptoms, so diagnosis should precede replacement.

Why Replacement Matters

Deposits, spindle wear or control faults can interfere with consistent airflow regulation. Replacement may be appropriate when testing confirms damage or malfunction that cleaning cannot resolve. Inspect adjoining seals, intake connections and wiring at the same time, and follow the vehicle-specific adaptation procedure where required.

FAQs

Can cleaning resolve the problem?
Cleaning may help when contamination is responsible. It will not repair worn mechanical parts or failed electrical components.

Will it fit every listed vehicle without other changes?
No. Some applications require a matching 82mm competition plenum. Check the existing intake arrangement and connection details.

Is adaptation needed after installation?
Some electronic throttle systems require a relearning procedure. Follow the instructions for the exact vehicle and engine.

• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02
• Porsche Boxster 986 2.7L 2003-04

Diagram Ref No 1

Featuring a precision-machined throttle valve, durable housing and integrated electronic or mechanical control interfaces (depending on vehicle application), the throttle body accurately controls airflow based on accelerator pedal input and engine management system demands. Designed to withstand continuous operation in demanding engine bay conditions, it provides reliable performance and seamless compatibility with the vehicle's engine management system.  

What This Product Does:

• Regulates the amount of air entering the engine.
• Controls engine power output in response to throttle input.
• Supports accurate fuel and air mixture.
• Maintains stable idle speed.
• Improves throttle response and engine drivability.
• Helps optimise fuel economy and exhaust emissions.
• Communicates with the engine management system for precise airflow control.
• Forms a critical part of the engine intake and fuel management system.

Symptoms Of Wear Or Failure:

• Rough or unstable idle.
• Hesitation during acceleration.
• Poor throttle response.
• Engine warning light illumination.
• Reduced engine power or limp-home mode.
• Sticking or binding throttle valve.
• Fluctuating engine speed.
• Increased fuel consumption.
• Difficulty starting the engine.
• Diagnostic fault codes relating to the throttle control system.

Why Replacement Matters:

• The throttle body is continuously exposed to airflow, carbon deposits, oil vapours and engine heat. Over time, contamination can restrict throttle valve movement, while internal components or electronic actuators may wear or fail, affecting airflow control and engine performance.
• A faulty throttle body can lead to poor acceleration, unstable idle, increased fuel consumption and reduced overall drivability. In more severe cases, the engine management system may activate limp-home mode to protect the engine, significantly limiting vehicle performance.
• Replacing a worn or malfunctioning throttle body restores precise airflow control, improves engine response and helps ensure smooth, efficient operation. An OE Match replacement provides factory-style fitment, dependable performance and long-lasting durability, helping maintain the power, efficiency and driving experience expected from your Porsche.

What This Product Does

The throttle valve varies the intake opening to meter incoming air. On electronically controlled applications, its movement is managed by the engine control system in response to operating conditions and accelerator demand.

Functions

• Adjusts the intake airflow entering the engine.
• Supports airflow regulation during idling and changes in engine load.
• Provides the controlled throttle opening required by the engine-management system.
  
  

Technical Details

• Product reference: 99760511502.
  
  

Symptoms of Fault

Possible signs include fluctuating idle speed, hesitation, stalling, delayed accelerator response, throttle-position faults or restricted-power operation. Intake leaks, wiring faults and other engine-management problems can produce similar symptoms, so diagnosis should establish the cause before replacement.

Why Replacement Matters

Replacement may be appropriate when contamination cannot be resolved by suitable cleaning, or inspection confirms mechanical wear or an electrical fault. Check adjoining intake connections, sealing surfaces and electrical terminals during the repair. OE Match focuses on Porsche replacement applications; matching the original reference remains essential.

FAQs

Will cleaning resolve the problem?
Cleaning may help when deposits interfere with movement. It will not repair worn components or failed electrical elements.

Is adaptation needed after installation?
Some applications require a throttle relearn. Follow the procedure specified for the individual vehicle.

Is a fault code enough to confirm failure?
No. Check wiring, air leaks and measured throttle operation alongside stored diagnostic information.
