Yes I have. It is in the mid to high 18psi range when the valve begins to open.

This confirms that the Tokyo Roki, did in fact, not meet Subaru specs and hence the change to the Honeywell....just wish they would have made them do a non-cardboard endcap.
What I will say about the Honeywell Subaru filter is it has much more pleats and what seems to be better sealing ABDV-to-cartridge and BV-to-cartridge junctions relative to an Orange Fram. Suffice it to say, I will be using the OEM one until my warranty runs out. I have contacted Wix, Bosch/Purolator, and Champion Labs with this concern. Hopefully if enough Subie owners voice this concern, they may have a new one for us in a few years.
I would use the Purolator XX14460 if it would fit my car though...it has the right bypass spec, but no ADBV, which at this point, I don't care about since it has next to no point on a vertical filter that is located as low as Subaru filters are located.
