Fair enough and you have explained this in better terms than the guy @ Firestone tires explained it to me, they do the very same thing for the very same reason ~ co$t reduction and damn the quality .
Nevertheless, millions upon millions of these filters have been and continue to be used world wide daily .
A good mechanic or DIY'er should be able to learn from experience, not go off in a huff like a 5 year old child .
I'm old and retired yet I still enjoy learning daily .

My logic is based on the fact that you have no way of verifying how much regrind was used in the plastic when the filter was injected into the mold. Regrind is the term used in plastic injection molding that refers to plastic material that has been heated to the melting point and not used. This could be from the sprue in the mold or just overflow from worn mold. This plastic waste is collected and ground up and added to virgin plastic in order to save money Every plastic material specification has a limit on how much regrind is allowed to be mixed in. Exceeding the regrind amount degrades the ability to meet its engineered specifications. If your making Happy Meal toys your more worried about color and inclusions. If your making pressure vessels there are obviously other concerns. My point is that there are no checks and balances other than you suing the company if the filter splits due to bad plastic. If General Motors is unwilling to go down that road that's good enough for me.
