OEM stands for original equipment manufacturer. The original manufacturer of the auto parts sold at Penske Chevrolet of Cerritos is GM. Aftermarket auto parts are parts made by third party companies based on OEM part designs.
Which is better? Honestly, OEM parts are going to be your best option more often than not because the OEM designs both the vehicle and the part. The same design specs are used and the same factory makes the part, which means there will be less of a discrepancy from part to part. You will also always have some kind of warranty with the part.
This is not to say all aftermarket parts are bad though. You can find good alternative aftermarket parts that will be comparable to auto parts made by OEMs. They are just harder to come by and might not always fit as well as OEM auto parts; they also don’t always come with warranties. If you’re looking at aftermarket parts that are considerably cheaper in price, chances are they are made cheap and will break down faster.
