Product Description

The Bosch 0280750473 is an 82mm drive-by-wire electronic throttle body manufactured in Germany to OEM Porsche specifications (Porsche PN: 99760511601). It serves as the factory-correct replacement throttle body for 2007-2016 Porsche 911 variants including the GT3, GT3 RS, GT3 RS 4.0, and 997.2/991 Carrera family, as well as 4.8L Cayenne and Panamera models and the 918 Spyder. With its large 82mm bore, this unit flows substantially more air than the base 74mm throttle body, and is the required component when upgrading with IPD competition plenums or other high-performance intake systems that demand 82mm throttle body clearance.

The assembly integrates the throttle actuator motor, throttle plate, and dual-redundant throttle position sensors into a single precision-machined aluminum housing. A new gasket (sold separately) and throttle body adaptation procedure using a Porsche PIWIS or compatible diagnostic tool are required during installation. The Bosch 12-month warranty applies.
