Porsche 911 Throttle Installation (EFI) Kit with ECU/Engine Harnesses & Base Map Package (Model Years 1978-1989)

 

AT Power has developed a unique range of Direct to Head Individual (Electronic Fuel Injection (EFI)) Throttle Body systems with complete (EFI) Installation Kits available 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 Electronic Fuel Injection Installation kits are supplied with an Individual Throttle Body system (ITB's) and all the supporting electronic engine management, fueling, vacuum, Oil breather, air filtration and heater systems required to make a complete (EFI) conversion to your Porsche. 

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.
