Bosch 68mm Electronic Throttle Body – Includes connector and pins Diameter: 68mm

Optimized Response: Bosch 68mm Electronic Throttle Body

The Bosch 68mm Electronic Throttle Body is designed for applications where throttle response and precise metering are prioritized alongside increased flow. A step up from the standard 60mm unit, the 68mm bore offers improved breathing capabilities for naturally aspirated engines and moderate turbo builds without introducing the “tip-in” sensitivity issues sometimes associated with vastly oversized throttles. This unit is a staple in the performance aftermarket, used extensively on modern engine swaps and ECU upgrades where Drive-By-Wire (DBW) functionality is desired over unparalleled peak flow. By utilizing an electronic actuator, the Haltech ECU can manipulate airflow independently of the driver’s foot to stabilize idle, smooth out gear shifts, and manage traction loss.

System Integration

Like its siblings in the Bosch motorsport range, the 68mm unit features a standardized 6-pin interface carrying motor power and dual redundant sensor signals. It is built to OEM durability standards, capable of surviving the vibration and thermal cycling of a competition engine bay. The included connector set facilitates a professional installation. This size is often the maximum recommended for stock intake manifolds on many 2.0L – 3.0L engines before port matching or manifold replacement becomes necessary.
