I got a response from Purolator this morning. Here it is in its entirety:
Hi Chris,
Thank you for your interest in our Purolator filters. I have contacted our Engineering Department with attached pictures for comment. I have received an answer back from them in which, they would like to get the filters in for testing. I will need to complete a quality concern. I have listed the information that I need below in order to complete this concern as well. Do you still have the filter/filters. You mentioned 7. I can request a call tag for all 7 in which is pre-paid at no charge to you. Please let me know if this is what you would like to do.
Name: (no Po box)
Address:
Phone:
Date of occurrence:
Filter number:
Number of filters:
If you have any questions, please let me know. As soon as you can get this information back to me, I can complete the QCR. Once I get it completed, it takes 2-3 days UPS ground to get to you. You would then just send the filters to the address provided. Once the claims lab gets the filters and completes their investigation, they will contact you directly from there.
Thank you,
Happy Holidays,
Katrina S. Hull

In the signature line it did say they are part of Robert Bosch, LLC.
I have sent in my response with the pertinent information as well.
