DISA Intake Manifold Adjusting Unit

Located on the upper portion of the intake manifold, this unit is a common source of issues like idle hesitation and low-end performance problems. By artificially lengthening the intake runner at low RPMs, the DISA valve boosts low-end torque. Conversely, at higher RPMs, it shortens the runners to deliver more peak power. A malfunctioning DISA valve can manifest in several ways, including rough idling, hesitation during acceleration, lean diagnostic trouble codes (DTCs), and unusual noises emanating from the engine bay.
