A worn valve spring can cause poor sealing and reduced compression in the valvetrain. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB09012-40010. The valve spring applies force to close the valve against its seat, maintaining proper timing. A broken spring may lead to valve float, resulting in power loss or internal damage. During high-rpm operation, spring fatigue can accelerate wear on adjacent components. Verify the serial number or application, then call (562) 693-7748. This part is a retaining ring category item, not a complete assembly.

Part number variants: MB09012-40010, mb09012-40010, MB0901240010, mb0901240010
