AT Power ‘Shaftless’ Individual Throttle Bodies

We keep 2 and 3 bolt 42mm port with 45mm throttle in stock.

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, 914/6, 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.

These 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 Big Bore velocity stacks with race mesh

• Vacuum Take-Off Kit with idle control valve

• Throttle position sensor (TPS)

• Billet aluminium fuel rails

• Optional 6 x Bosch 0280158038 EV14KT short Fuel Injectors

• Thermal insulation gaskets

• Throttle linkage system which connects directly to the existing OEM cable pick-ups
