Are Toyota Parts Better Than Aftermarket Parts?

Q: Are Toyota Parts Better Than Aftermarket Parts?

A: Toyota OEM Parts are manufactured by Toyota to Toyota's exact specifications. Though aftermarket parts may cost less than OEM parts they do not necessarily offer better value. Aftermarket parts are often made to lesser standards than Toyota Genuine parts and may be prone to a higher failure rate.
Genuine Toyota parts are designed to fit your specific Toyota vehicle whereas most aftermarket parts are made to fit multiple vehicles and may not fit correctly. 

So what are "aftermarket" parts? 
Aftermarket parts are parts that are not made by the vehicles manufacturer but by a third party. These third parties often try to copy the look of the factory part but neglect the precision fit of the OEM part. Toyota has a reputation for reliability and that reliability is due to the quality of parts used when manufacturing the vehicle.
