Porsche 993 45mm

These Direct-to-Head Porsche 993 45mm Throttle Bodies are port matched with a round throttle plate. This is a direct mounting to the cylinder head so no additional manifold is required. These throttle bodies feature round, 'shaftless' and knife-edged butterflies for improved airflow & performance and with the throttle blade very close to the inlet valve the engine response is significantly improved. 

Delivered fully assembled, made from Billet aluminium, with a Billet Aluminium Fuel Rail, Choice of Inlet Lengths and calibrated for your choice of TPS. Engine management is the only additional part required to achieve significant power gains. Our Linkage setup allows you to connect directly to the existing OEM throttle cable linkage. 

Available with either a 42mm inlet port size (cylinder head) or 44mm for ported cylinder heads.

'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.'
