AT Power has developed a unique range of Shaftless Butterfly Direct to Head Individual (Electronic Fuel Injection (EFI)) Throttle Body systems for the Porsche 911, 964 and 993, Air-Cooled Classics. The air-cooled Porsche models suits our beautifully manufactured 'Shaftless' Throttle technology perfectly.
Our unique patented technology helps to increase air flow dramatically thus minimising air flow separation and reduces turbulence, resulting in higher volumetric efficiency.
This pristine technology with Knife-edged butterflies has improved inlet airflow and performance significantly. With the individual Throttle blades very close to the inlet valves, the engine and Throttle response are vastly improved. Along with this, we have also found an impressive increase in Horsepower, Torque, Driveability, and an incredible mechanical soundtrack.
With over 10 years of manufacturing Motorsport parts and a combined experience of over 60 years of automotive design, we truly believe our outstanding throttles solution will yet again, change the way you feel, about your Porsche.
This system has been designed to be a “bolt on kit” thus allowing the vehicle to be returned to its original condition, if required.
Installation Packages are suitable for Porsche 964/993 (Model Years 1989-1998). Contents illustrated may vary dependent upon individual applications.
