A. Aluminum alloy material with good processing performance, welding characteristics and electroplating, corrosion resistance, toughness, no deformation after processing, compact material without defects, easy to polish, easy to color film, and good oxidation effect.<br> B. It has strength and durability. This boost solenoid valve uses a fully adjustable actuator arm and lock nut 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.<br> C. Specification:<br>Spring pressure: 0.5-1.79bar<br>Features: Positive pressure valve<br>Other parts (installed and internal)<br>Applicable models: Universal<br>colour: red<br>Material: aluminum alloy<br>size: 21x6.6cm<br> D. Package Contents:<br>1 * adjustable actuator<br>1 * spring<br>Only the above package content, other products are not included.<br> E. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
