1. High-quality aluminum alloy, with good processing performance, welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, material without defects, easy to polish, easy to color film, and oxidation effect Good and other features. 2. It has high strength and durability. This boost solenoid valve uses a fully adjustable actuator arm and lock nut for precise boost setting. The position of the is accurate, and it is easy to install without adjusting the turbocharger. A heavier spring keeps the wastegate valve , thereby increasing power, -range acceleration and preventing wastegate flapping. Increase the boost output of the turbocharger system.
