What This Product Does
The kit adapts large-volume 996 GT3-style intake manifolds and Bosch electronic throttle control to compatible air-cooled Porsche 911 engine builds. Adapt Motorsport intake components account for the shorter cylinder spacing of air-cooled engines and provide the fuel-rail, resonance-flap and vacuum-control hardware needed to complete the intake assembly.
Functions
- Regulates intake airflow through an 82mm Bosch electronic throttle body
- Connects GT3-style intake hardware to two-bolt air-cooled cylinder heads
- Supports short, medium or long EV14-style fuel injectors using the appropriate rail spacers
- Controls the intake resonance flap through a vacuum canister, solenoid and check valve
- Provides vacuum connections for the brake booster, idle-air bypass and supporting systems
- Measures manifold pressure and intake temperature through a Bosch T-MAP sensor
Technical Details
- 996 GT3-style intake manifold port diameter: 49mm
- Two-bolt adapters: 40mm or 42mm ports for 2.7, 3.0 and 3.2 engines
- Bosch electronic throttle body diameter: 82mm
- Standard Bosch T-MAP sensor rating: 1.15 bar; a 3.0-bar version is offered separately
- AMS manifolds use cast-aluminium construction, while the resonance flap and intake T-piece are CNC-machined and black anodised
Base Kit Contents
- AMS high-flow intake T-piece with vacuum and T-MAP sensor connections
- AMS fuel rails with fittings
- Bosch 82mm electronic throttle body and connector kit
- AMS CNC-machined resonance-flap assembly with sealed roller bearings
- Bosch 1.15-bar temperature and pressure sensor with connector
- Throttle, resonance-flap and intake-adapter sleeves with hose clamps
- Vacuum canister, solenoid, check valve, electrical connector and hoses
- Required fasteners and fittings
Configuration Information
Separate versions accommodate two-bolt and three-bolt cylinder heads, with the relevant adapter port sizes. Each configuration can be supplied either with or without a pair of AMS GT3 intake manifolds, so the cylinder-head pattern, port diameter and manifold requirement must be confirmed before selection.
FAQs
- Is the electronic throttle body included?
Yes. Every base kit contains the Bosch 82mm electronic throttle body and its connector kit. - Are intake manifolds supplied?
This depends on the chosen configuration. Adapt Motorsport offers versions both including and excluding the pair of AMS GT3 intake manifolds. - Does the system require calibration?
Yes. The electronic throttle, T-MAP sensor, injectors and resonance-flap controls must be configured within a compatible engine-management system. - Which cylinder-head patterns are supported?
Two-bolt versions suit 2.7, 3.0 and 3.2 engines, while three-bolt versions are intended for 964 and 993 3.6-litre applications.
