Thank you sir

I am not quite sure
@53' Stude , it's funny that you ask because: when I was at O'Reilly's there was nobody else there, so the young man behind the counter and I were chit-chatting because I was curious as to why this one had a nitrile ADBV and the previous ones that I have purchased have had silicone ADBV's. We went and grabbed a Wix 57099 and held them side by side and they looked identical besides the ADBV's (Wix was silicone), so I assumed that it was made by Wix, but I honestly do not know. The Wix was a hair more than double the price so I went with the MicroGard, since it is still made here in the USA. Perhaps this particular filter number is outsourced by Wix for both their own filter and for MicroGard??? I'm not too sure, but I'm curious
