LOCK - FILTER (Mitsubishi MB2W4391)

A damaged filter lock can allow unfiltered contaminants to bypass the filter element entirely. During operation, a loose or missing lock may cause the filter to shift, leading to reduced filtration efficiency. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB2W4391. The lock secures the filter in place, ensuring a sealed connection between the filter and its housing. A common failure consequence is that a compromised lock can result in debris entering the system, accelerating wear on downstream components. The item ships at approximately 0.912 pounds.
