Intake Manifold Control Plate — Opel Z14XEP / Z12XEP Twinport | OEM 5850676 / 24420528

Restore Twinport Variable Intake Function on Your Opel — Replacement Control Plate.

The Opel Z14XEP and Z12XEP Twinport system uses a control plate to actuate the variable intake flaps. When this plate wears, cracks, or breaks, the Twinport system stops switching correctly — causing rough idle, reduced low-end torque, and intake-related fault codes. This replacement control plate restores correct Twinport operation.
