We carry a variety of parts related to BMW throttle bodies and throttle body upgrades. Modern BMWs have electronic throttles that need replacement rather than repair. A malfunctioning unit can disable the car so it's important to pay attention to any fault codes related to the 'EML' system. Older mechanical throttles are much more reliable and less prone to any issues. Replacement of any throttle housing is easy and straightforward.
Larger throttle bodies have been advertised for years as a performance upgrade. On their own they will not make any power difference. But combined with other upgrades, such as larger mass air sensors and intakes, they can contribute to power gains. However, we do not currently sell larger throttle bodies. We do offer adapter plates to mount different throttle housings onto your intake manifold. This is most commonly done along with a stand-alone engine management system with or without drive-by-wire control.
If your S85-powered M5 or M6 has recently gone into "limp mode" and tripped some engine codes, you may have a faulty throttle body actuator. The plastic gear teeth become rounded and broken over time, resulting in poor or no throttle response to your input. Replace your throttle body actuators to restore throttle response and prevent any additional operational issues! Included: OEM VDO Throttle Body Actuators Genuine BMW Throttle Body Actuator Arms
