GT1446MZG Turbocharger for Vauxhall/Opel Astra J, Corsa E, Insignia A 1.4 Turbo | OEM 55565353, 781504

The GT1446MZG Turbocharger – OEM 55565353 (also referenced as 781504-0007, E55565353, E55565354) is a direct-fit turbocharger unit designed to restore performance and boost efficiency on 1.4 litre turbo petrol engines fitted to a number of Vauxhall/Opel and related GM vehicles. This turbocharger increases the amount of air delivered to the engine, enhancing power output, torque response and overall engine efficiency compared with naturally aspirated operation. When the original turbo loses boost or begins to fail, replacing it with a GT1446MZG unit ensures your engine achieves proper boost pressure and smooth acceleration.
