Valve Adjusting Screw

About this product

The Valve Adjusting Screw (#90913-05020), an integral component in the Camshaft & Valve system of the Engine-Fuel parts category, regulates the gap between the valve stem and the rocker arm. It works while the engine is running, controlling the opening and closing of the valves for fuel intake and exhaust. Over time, wear and tear can disrupt this precision, causing the screw to become ineffective. A worn out Valve Adjusting Screw (#90913-05020) can lead to improper fuel intake and exhaust, resulting in decreased engine performance and increased fuel consumption. By using genuine Toyota auto parts like the Valve Adjusting Screw (#90913-05020), you benefit from optimal vehicle compatibility and the assurance of Toyota's genuine parts warranty.
