Designed for air-cooled six-cylinder Porsche engines from 1965 to 1998, PMO individual throttle bodies combine the classic appearance and response of traditional carburettors with the accurate fuel control and tuning possibilities of modern EFI.
The Black Anodized “R” finish gives the throttle bodies a
purposeful vintage competition appearance, making them particularly suited to
performance, restomod and motorsport-inspired Porsche engine builds.
Inlet Manifolds, Fuel Injectors and Throttle Position Sensor (TPS) are Not Included
Please note that inlet manifolds, fuel injectors and the TPS shown in product imagery are for reference and are not included with the kit.
What Does the PMO EFI Throttle Body Kit Do?
PMO individual throttle bodies replace carburettors or the existing induction system as part of a complete electronic fuel injection conversion.
Each cylinder receives its own throttle bore, providing direct and responsive airflow. Fuel is delivered through individual injectors controlled by a compatible programmable ECU.
When correctly installed and tuned, benefits can include:
- Sharper throttle response
- Precise electronic fuel control
- Improved engine tuneability
- Better cold starting and driveability
- Accurate control of air/fuel ratios
- Potential improvements in performance and fuel efficiency
- Individual throttle response for each cylinder
- Classic competition appearance with modern EFI technology
40mm, 46mm or 50mm – Which Size?
PMO offers three throttle body sizes to suit different
air-cooled Porsche engine specifications.
- 40mm – Ideal for smaller-capacity and road-focused engines where good air velocity, throttle response and low-to-mid-range performance are important.
- 46mm – Suitable for larger-capacity, fast-road and modified engines requiring increased airflow while maintaining excellent throttle response.
- 50mm – Designed for highly modified, large-capacity and competition engines where maximum airflow and high-RPM performance are required.
Correct sizing depends on engine capacity, cylinder heads, camshafts, compression ratio, intended RPM range and power requirements. Consult your engine builder when selecting the appropriate size.
Precision PMO Construction
PMO EFI throttle bodies are precision CNC machined and hand assembled in Anaheim, California using aerospace-grade materials.
Sealed ball bearings provide durability, while the one-piece throttle shaft maintains accurate alignment for smooth and consistent throttle operation.
Tapered 52mm intake throats improve airflow into the throttle bodies, while billet fuel rails accommodate Bosch-style fuel injectors.
EFI Management Compatibility
PMO EFI throttle bodies can be used with programmable engine management systems including Haltech, MegaSquirt, MoTeC and other suitable aftermarket EFI controllers.
The ECU must be correctly configured and tuned for the individual engine specification.
Injector size, fuel pressure, sensors and ECU configuration should be discussed with your engine builder or EFI system supplier before installation.
Converting from Carburettors to EFI
A carburettor-to-EFI conversion requires a suitable high-pressure fuel system in addition to the throttle bodies.
A fuel pump capable of approximately 60 psi is required. The Walbro GSL393 external universal inline fuel pump, rated at approximately 160 LPH, is one suitable option. Another correctly specified 60 psi EFI fuel pump can also be used.
Fuel lines, filters, pressure regulation and associated components must be suitable for EFI operating pressures.
Associated components to add include:- Fuel rail retaining/injector clip – 534-102
- TPS sensor – 17123852
- Bosch-style fuel injectors
- Suitable high-pressure EFI fuel pump
- Compatible programmable ECU
Fuel injector specification should be selected according to engine capacity, expected power output, fuel type and EFI system requirements.
PMO Black Anodized “R” EFI Throttle Bodies for Air-Cooled Porsche
PMO individual throttle bodies provide an excellent solution for Porsche owners wanting the immediate response and appearance of classic individual induction combined with modern electronic fuel injection.
Available in 40mm, 46mm and 50mm sizes, the system can be matched to road, fast-road, restomod and competition air-cooled Porsche flat-six engines.
The Black Anodized “R” finish provides a distinctive period motorsport appearance, making these throttle bodies particularly suited to classic Porsche 911 performance builds where engine-bay appearance is as important as performance.

Patented technology that helps to increase air flow dramatically thus minimising air flow separation and reduces turbulence, resulting in higher volumetric efficiency.
This pristine technology with Knife-edged butterflies has improved inlet airflow and performance significantly. With the individual Throttle blades very close to the inlet valves, the engine and Throttle response are vastly improved. Along with this, we have also found an impressive increase in Horsepower, Torque, Driveability, and an incredible mechanical soundtrack.
Throttle Bodies come fully assembled and ready to bolt directly to the Cylinder Heads, with the following parts included:
• Anodised Aerospace Grade 6082/T6 Billet Aluminium "Shaft-less" Individual Throttle Bodies.

Porsche Electronic Fuel Injection Throttle Kits - Precision Airflow & Throttle Control
Electronic Fuel Injection (EFI) Throttle Kits upgrade the engine’s air delivery system, providing precise throttle control, improved airflow, and enhanced engine response. Designed for performance builds, engine conversions, and modernised classic Porsche applications, these kits replace restrictive or outdated throttle systems with advanced electronic throttle bodies and control hardware.
Available from Design911, Porsche EFI throttle kits are engineered to deliver smoother power delivery, sharper throttle response, and improved drivability—especially in tuned, high-performance, or track-focused engines.
What Do Electronic Fuel Injection Throttle Kits Do?
EFI throttle kits regulate the volume of air entering the engine with high precision, directly influencing power and response.
Core Functions:
- Control engine airflow electronically and accurately.
- Improve throttle response and drivability.
- Support higher airflow demands in tuned engines.
- Enable precise fuel and ignition mapping.
- Enhance overall engine efficiency and performance.
Accurate throttle control is essential for modern performance engine management.
Why Do Standard Throttle Systems Fail?
Factory or older throttle systems can become limiting or
unreliable over time, particularly in modified engines. Common issues include:
- Mechanical throttle wear or cable stretch.
- Inconsistent airflow from ageing throttle bodies.
- Restrictive designs limiting high-RPM performance.
- Poor compatibility with modern ECU tuning.
- Inadequate response for high-performance applications.
These limitations can result in sluggish response, uneven power delivery, and reduced tuning potential.
Why Upgrade to an EFI Throttle Kit?
EFI throttle kits are designed to support modern engine management and higher performance demands.
Upgrade Benefits:
- Sharper, more consistent throttle response.
- Increased airflow capacity for power upgrades.
- Improved compatibility with aftermarket ECUs.
- Enhanced drivability for road and track use.
- Ideal for engine builds, conversions, and restorations.
Upgrading to an EFI throttle kit unlocks precise control and maximises engine tuning potential.
