MB1W4107: A worn piston can reduce compression and cause excessive oil consumption. The Mitsubishi catalog reference MB1W4107 identifies this aftermarket replacement part. This piston is an oversized .040 unit, which accommodates cylinder bore wear during rebuilds. Its primary function is to transfer combustion force to the connecting rod. A common failure consequence is blow-by, where combustion gases escape past the rings. Verify the serial number or application, then call (562) 693-7748.

Part number variants: MB1W4107, mb1w4107
