Diagram Ref No 12

What This Product Does:

• The intake pipe (or intake connection) is a critical component in the engine’s air delivery system: it connects the throttle body, intake stack or air intake system to the intake manifold of the engine.
• It ensures a smooth, sealed, correctly shaped passage of air (and in the case of injection, the air-fuel mixture) into the cylinder head, maintaining correct airflow, avoiding leaks or turbulence that could upset fuel/air metering or engine response.
• On the era of 911 referenced (MFI mechanical fuel injection), proper intake piping is important for correct function of the injection system, throttle response, and overall engine performance.

Symptoms Of Wear, Damage Or When Replacement Matters:

• Air leaks or a hissing sound around the intake pipe, which can upset the injection/air-metering system, cause poor running, unstable idle or reduced performance.
  
• Poor throttle response, hesitation or mis-firing — if the pipe is cracked, partially blocked, or has missing components, it can degrade engine performance.
  
• Cracks, corrosion, or broken mounting tabs visible on the pipe or its flanges — especially for older vehicles where plastic/metal parts have aged.
  
• Difficulty fitting or aligning connections between the throttle stack and manifold — if the pipe is out of shape or damaged, it may be difficult to achieve correct installation or clean sealing.
  
  

Why Replacement Matters:

• Ensures correct airflow and engine performance: A damaged or sub-standard intake pipe can compromise air delivery, disrupt mixture control, and reduce engine efficiency or driveability.
  
• Improves reliability: Old or worn intake components can lead to leaks, performance issues or even engine damage (if mixture is upset or induction temperatures become erratic). Replacing with a correct part restores the system.
  
• Simplifies installation: Buying a “complete” intake connection (rather than patching multiple smaller pieces) saves installation time, reduces risk of missing parts, and ensures compatibility.
• Ensures fitment integrity: In older vehicles, mounting points may have degraded—installing a new pipe with correct flanges/hardware ensures everything aligns properly, reducing stress or potential leaks.

Fuel injection throttle body kit with air horns - Without fuel injectors



Fits:
Porsche 911 2.0ltr - 1965 to 1968
Porsche 911 2.2ltr - 1969 to 1971

Sizes Porsche 911 intake manifolds
Carburetor/Bosch MFI Ø32mm engine side - Ø40mm ITB side. Recommended for early 2.0ltr / 2.2ltr engines

Injectors options that can be used - 260cc / 300cc / 380cc / 420cc / 480cc / 520cc

This is a direct replacement kit for replacing carburetors while keeping the OEM look in your engine bay. 

The intake manifolds and riser plates are manufactured out of a single piece of 6082 aluminum and come in 2 styles. These differ in design due to the shape of the mounting flange for the cylinder head. The intake manifold can be used as replacement parts for the OEM part when damaged or has to be replaced*.
The ITBs are manufactured out of cast aluminum, whist the fuel rails are made out of aluminum 6060 extrusion profile and come with AN6 ORB connection for the fuel lines. The direct mount fuel pressure regulator is directly mounted to the fuel rails, so in this case you don’t need to drill additional holes in the engine bay for mounting a fuel pressure regulator.
The throttle linkage and all mounting hardware is made from stainless steel and the pivoting point of the throttle linkage is a ball and socket design for smooth operation. The levers allow you to adjust and finetune mechanical movement of the ITBs

The dimensions of the assembly are the same as the OEM carburetor setup and the riser plate comes with same mounting holes as the OEM carburetors, in this way you are able to use the OEM air filter box and OEM airhorns. Also the riser plates come with mounting options for an air intake temperature sensor, this is nicely hidden away between the ITBs. The diameter for the ITBs in the riser plate is 45mm. There is also an option for using airhorns, In this case you don’t need the riser plates.

The crank sensor and trigger wheel kit are additional and this type of kit is needed when using ITBs like these. Besides switching to ITBs you will need a stand alone ECU to get the fuel injection to work. Our kit only works with engines like the 3.0ltr that came with a “ big distributor”. You can leave the distributor or you can remove this unit when you are going to use a discoil type of ignition. In for case an adapter is included in the crank sensor kit. The pulley comes in 2 dimensions to choose from, a Ø116mm pulley and Ø126,5mm pulley.

Fuel injectors, fuel lines, standalone ECU, wiring harness are NOT included in the kit.

*In case of using as a replacement part 3 mounting holes for the carburetors or ITBs need to be re thread with a timesert or helicoil. Otherwise it is impossible to mount a threaded stud.

Kit Includes
2 x Full billet, hard anodised intake manifolds
6 x ITB complete with lever assembly
6 x Airhorns 45mmØx30mm
2 x Fuel rail with mounting hardware
1 x Throttle linkage with 2 throttle connection rods
1 x Direct mount fuel pressure regulator
2 x Riser plates with 1 air temperature sensor (for use with OEM air filter box)

Intake manifold for the 1969 model year Porsche 911E and 911S only. 

The 1969 model year 911E and 911S were the first 911 models with the mechanical piston pump injection system (MFI). 

The diameter is 36mm to the throttle body and 38mm to the velocity stack and the pitch of the studs to the throttle body is 66 mm. 

These intake manifolds are identical on the left and right and are sold separately - 2 required per car

Inlet manifold adaptor kit, 2 bolt cylinder head for EFI (electronic fuel injection) conversion . 

Fits:
Porsche 911 / 911S 2.7ltr - 1974 to 1977
Porsche 911 SC - 1978 to 1983
Porsche 911 3.2 Carrera - 1984 to 1989

These adapters are used to modify the 2.7ltr / 3.0ltr / 3.2ltr Porsche 911 2 bolt cylinder head engines to the later 964 / 993 3.6ltr intake manifolds when converting to EFI.  

CNC machined on a 5 axis machine to our exacting tolerances and finish and anodised dark grey these are custom machined to match your port diameter and tapered to fit up to the 42mm inlet manifold port size.

The short adapor height maintains the overall height of the intake set, reducing the interference between the idle air control, the intake boot and the top of the engine bay insulation.  The factory plastic 3 bolt 964 stacks are too tall, and adding an adapter spacer would make the manifolds not fit at all.

This design permits the use of the standard 964 fuel injectors and fuel rails so positions the injector over the same relief in the intake port for the original CIS injector, ensuring proper atomisation of the injector spray into the intake port.

Key Features:
Precision machined from high grade aluminium
Anodized finish
Fits all Bosch 14mm O-ring fuel injectors
Fuel rail spacers are marked for easy cutting to suit long, medium or short injector types.

Kit Includes:
6 x CNC aluminium adapters
4 x Spacer/Posts for fuel rail 
4 x Bolts to suit standard full length Bosch injectors
12 x Nuts and washers 

Fuel rails not included in kit
