1. High-quality aluminum alloy, with good processing performance, excellent welding and electroplating characteristics, good corrosion resistance, high toughness and deformation after processing, compact material without defects, easy to polish, easy to color film and oxidation effect and other excellent features. 2. It has high strength and durability. This boost solenoid valve uses a fully adjustable actuator arm and locknut for precise boost adjustment. The bolt position is accurate and it is easy to install without adjusting the turbocharger. A heavier spring holds the wastegate longer, thereby increasing horsepower, mid-range acceleration torque and preventing wastegate flapping. Increase the boost power of the turbocharger system.
