Porsche 993 45mm (EFI) Throttle Bodies


AT Power has developed a unique range of Direct to Head Individual EFI Throttle Bodies 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.

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 993 - 3.6L engines (Model Years 1995-1997). Contents illustrated may vary dependent upon individual applications. 


Our Throttle Bodies come fully assembled and ready to bolt directly to the Cylinder Heads, with the following parts included:

• Aerospace Grade Billet Aluminium “Shaft-less” Individual Throttle Bodies.

• Aluminium Inlets/Extensions are suitable for duck or whale tail models.

• Aluminium Ram Pipes.

'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.'
