SPRING - VALVE INNER (Mitsubishi MB067-6053)

MB067-6053: A worn valve spring can cause poor sealing and reduced compression in a combustion chamber. The MB067-6053 part is an aftermarket replacement for the Mitsubishi catalog reference. This inner valve spring provides the mechanical force to close the valve against its seat. A broken or fatigued spring may lead to valve float, risking piston contact and internal damage. During high-rpm operation, consistent spring tension is critical to maintain valve timing. The part is a retaining ring category component, not a complete assembly. Verify the serial number or application, then call (562) 693-7748.
