OEM Parts vs. Generic Auto Parts

Using the proper auto parts does more than just keep the vehicle running; certified parts keep the car running as it was designed to perform by making sure there isn't a "weak link" somewhere in one of the car's subsystems. One part which might work but isn't working as efficiently as possible means the entire system is compromised. In addition, when one system isn't working as intended, it puts additional strain on the surrounding systems because they are all linked. Each particular system relies on others to work properly.

The best thing that can happen with bad parts is they fail much sooner than expected and have to be replaced again. At worst, a failed part can cause other parts to fail, causing both a roadside breakdown and much more expensive repairs. Another problem that can occur is when maintenance is required, the technician working on the car will have problems diagnosing the cause of problems because they can't trust a recently replaced part is working properly. Part of diagnosing a problem involves looking into the history of repairs and trusting recently replaced parts to be working as new, but such a process doesn't work when generic parts that can't be trusted are scattered throughout the engine compartment and may or may not be working.
