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.

This precision-engineered throttle body adapter plate was originally developed for the Turner Motorsport SPEED World Challenge racing team. It enables the use of a mechanical throttle body in place of the M54 engine's factory drive-by-wire system, offering greater control and reliability for high-performance or competition use. Ideal for custom builds and race applications, this adapter plate ensures a seamless installation while retaining the structural integrity and alignment needed for optimal throttle performance.

Important Notes:

Designed specifically for professional racing applications. Requires the use of custom software for proper integration and functionality. Recommended for experienced tuners and mechanics familiar with custom engine configurations.
