Earlier this week, I posted a Ford video highlighting the difference between several Ford factory-approved parts and their aftermarket equivalents. The plot thickens. Yesterday, Consumer Reports reported that the Certified Automotive Parts Association (CAPA) has tested and approved exactly the sort of aftermarket part that Ford engineers dismissed in the video.
Here is the Consumer Reports piece.
Two other points worth mentioning:
1) The Ford video involved unusually rigorous stress tests, including seeing how easily an electric saw could cut through various car parts. In contrast, the CAPA tests focused on part performance during collisions, which seems to be more relevant. This could be a case of the Ford part being unnecessarily durable, thereby overserving (and overcharging?) the customer.
2) There is a comment in the Consumer Reports discussion board about the factory parts being priced similarly to the aftermarket parts. If that were true, and perhaps it is in certain cases, then it does seem obvious that the factory-approved parts are preferable.
