Electronic Throttle Body

The Bosch electronically-controlled throttle housing manages airflow into the intake manifold and signals throttle positions to the engine computer. This component is critical for proper engine operation, as a faulty unit can force the vehicle into "limp" mode, significantly reducing available power. The OE part number for this throttle body is 99760511601, and it features a 82 mm diameter. This specific Bosch throttle body is designed as a direct replacement for various Porsche models. It is essential to use the vehicle selector tool to confirm exact fitment for your specific year, make, model, and engine. While many Porsche 911 (997 chassis) and Cayenne models from 2008 through 2025 are listed as compatible, always verify with the vehicle selector. Some sources indicate this part is an upgrade that can produce more airflow, potentially leading to more power when used in conjunction with competition plenums, though this product is not marketed as a 'Performance Part'.
