What This Product Does

The kit provides the physical transition required to install 996 GT3 intake manifolds on compatible three-bolt air-cooled cylinder heads. Its short design limits the total height of the intake assembly, helping to reduce potential interference around the idle-air control components, intake boot and engine-bay insulation.

The injector is positioned over the original relief in the intake port. The adapters also provide mounting provisions for Adapt Motorsport fuel rails when the appropriate fuel-rail configuration is selected.

Injector Compatibility

The supplied fuel-rail spacer posts accommodate long-body Bosch EV1, EV6 and EV14 injectors. Markings on the posts allow them to be shortened for compatible medium- or short-length injectors. All injectors must use 14mm O-ring fittings.

Kit Contents

• Six CNC-machined aluminium intake adapters
• Four fuel-rail spacer posts
• Four bolts for standard full-length Bosch injectors
• Fuel rails and fittings when a fuel-rail kit configuration is selected

GT3 intake manifolds, rubber joiners, fuel injectors and hose clamps are not included. An advanced single fuel-rail option with an integrated pressure regulator and damper is available only with compatible adapter and fuel-rail kit configurations.

Power-Steering Compatibility

Versions identified as “No PS” are intended for installations without a hydraulic power-steering pump, including suitable G-model conversions or vehicles using electric power steering. No PS adapters will not fit a Porsche 964 or 993 while its hydraulic power-steering pump remains installed.

Why Correct Selection Matters

The adapter diameter should correspond with the measured cylinder-head port. Correct selection provides the intended transition into the head, while the appropriate height, injector arrangement and power-steering clearance allow the converted intake assembly to be installed as designed.
