The Tomei Turbocharger Kit Repair Part Arms Actuator Spring is designed as a direct replacement for worn or damaged actuator springs within Tomei turbocharger systems. It allows users to select a specific spring rate to tune their turbocharger's boost response. Available rates include 0.2kg/cm2, 0.5kg/cm2, 0.7kg/cm2, 0.8kg/cm2, 0.9kg/cm2, and 1.2kg/cm2, enabling precise control over boost pressure. In addition to performance tuning, these springs are offered in a variety of aesthetic colors, including black, blue, pink, purple, red, and silver, allowing for customization of engine bay appearance. The product is explicitly stated as not being an emissions item, simplifying installation in regions with strict emissions regulations. The MPN TB401B-SPR09 specifically refers to the purple color option for this actuator spring. Tomei is an authorized dealer for this component. It is important to note that this product does not have specific fitment application data provided; users are advised to verify compatibility manually with their existing turbocharger setup.
