Jenvey Porsche 911 GT3 (996) - SF51 Taper ITB Kit

The Jenvey Porsche 911 GT3 (996) - SF51 Taper ITB Kit (CKPE06-GT3) replaces the standard induction on the 996 GT3 engine with six SF51 taper individual throttle bodies and matching manifolds, for road, track and rally builds that want sharper response and more power.

Designed and manufactured by Jenvey Dynamics in the UK, Jenvey's individual throttle body systems are prized for crisp throttle response, strong torque and the unmistakable induction sound. An aftermarket ECU is required.

Key Features:

• Built & Balanced: Supplied assembled and balanced by Jenvey, ready to fit.
• Improved Fuel Mixing: Injectors sit further upstream, in the part-throttle turbulence of the butterfly, for better atomisation, torque and power.
• Maximum Flow: Profiled spindles minimise cross-sectional area at full throttle.
• Fine Low-Speed Control: A shallow 8° shut angle gives finer control at small throttle openings.
• Proven Durability: Major components are rig tested to over 1 million cycles.
• UK Made: Cast in Jenvey's own foundry and machined in the same UK factory; castings are lighter than fully CNC-machined parts.
• Modular System: Bespoke throttle sizes and system lengths can be built to order.
