Check fitment for your specific vehicle, including model, year, engine and intake-port diameter, before ordering.

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

• Six CNC-machined aluminium intake adapters
• Four marked fuel-rail spacer posts
• 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.

Intake manifold flange.
Build to Porsche specifications, this high-quality replacement ensures a perfect seal between the intake manifold and cylinder head, preventing boost leaks and maintaining consistent airflow.

Fits:
Porsche 911 (930) Turbo 3.0L / 3.3L 1975 - 1989
Porsche 964 Turbo 3.3L / 3.6L 1991 - 1994

Diagram ref no 7

This component is a metal intake flange that sits between the intake manifold assembly (where air and fuel enter the engine) and the cylinder head ports.
•  It acts as both a mounting surface and sealing interface.
•  It aligns and secures the manifold to the engine while maintaining a consistent, high-pressure seal.
•  It prevents unmetered air or boost from escaping the intake system.
In turbocharged engines like the Porsche 930 or 964 Turbo, maintaining this seal is critical for consistent boost pressure, efficient combustion, and throttle response.
