What This Product Does

This kit supplies the vacuum equipment required to operate the intake manifold resonance flap on a classic air-cooled engine conversion. Its components are arranged together on a nylon support bracket to simplify installation and vacuum-line routing.

Functions

• Provides vacuum actuation for the intake manifold resonance flap
• Maintains vacuum through the supplied reservoir and check valve
• Uses a solenoid actuator to control the vacuum circuit
• Connects the system through the supplied hose, T-piece and tubing

Technical Details

• Suitable for classic air-cooled engines using 964 or 993 intake manifolds
• Also designed for conversions using a 996 GT3 intake manifold
• Includes a vacuum canister, check valve and solenoid vacuum actuator
• Supplied with a solenoid connector kit, T-piece, vacuum hose and interconnecting tubing
• Automotive-grade nylon support bracket and installation fasteners included
• Mounts directly to the Adapt Motorsport 964 drive-by-wire throttle conversion kit; installation with the GT3 kit requires a separate bracket made by the installer

Check fitment for your specific vehicle, engine, intake manifold and throttle conversion before ordering.
