This adapter Kit converts the factory throttle body on the 2JZ-GTE VVT-i engine to a Bosch 74mm DBW (drive by wire) throttle body It also adapts the Bosch throttle body to either a coupler style or dual seal clamp style inlet.

The throttle body to manifold adapter is the interconnect between the throttle body and the factory 2JZ-GTE VVT-i intake manifold. This may be necessary when installing some aftermarket engine management units.

The Bosch DBW Throttle Body cannot be controlled by a factory ECU. You must have an aftermarket ECU in order to control it.
