Porsche 964/993 Electronic Fuel Injection (EFI) Throttle Bodies

 

AT Power has developed a unique range of 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 “Shaft-Less” 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 8 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 - 3.6L engines (Model Years 1990-1997). Contents illustrated may vary dependent upon individual applications.

'Comparison is between two identical stock Porsche euro spec 3.0 liter engines. Each motor also has 1.5 inch headers and racing mufflers. Both engines have the same fuel injection system and ecu. One has a reputable aftermarket throttle body system with 46mm diameter shaft butterfly. The other contains the AT Power designed throttle body system with 42mm shaft-less butterfly. Both runs were done in same ambient conditions on the same wheel dyno. All other specs on the cars are identical.'
