So perhaps that does lend some credibility to them claiming to perform their test IAW industry standards.
I agree, the Honda data does line up and therefore, the Toyota filter data is most likely correct.
After seeing the reviews on BITOG, I ran the Ultra for a bit, but there was some type of issue with the ADBV, so I removed it. As I reported in another thread, the 3 second knocking noise at start-up was something I don't want to hear again on our Lexus. Probably an isolated incident, but never heard it with the 90915-YZZD1 filter ($5 a piece delivered via Amazon). I wish I would have sent the used filter to Fram for testing; however, I sent to car51 to C&P.
Sorry OP, didn't mean to derail the thread.
