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