I use to always run them on my honda's , there great filters but if your looking for information on them you probably wont find much.

I'm going to order a couple and gut them and get some specs...I'm mainly interested in the bypass pressure spec. Since the black Tokyo Rokis that Subaru had as OEM didn't have the right bypass pressure, I'm assuming the same will be on these, but it's worth a shot.

^ Oh i forgot to mention the Hamps i was ordering in from japan some of them were marked "made in usa" and some "made in japan" The made in japan are made by toyo roki(not tokyo roki) and the made is usa ones are made by filtech. There both of the same quality thou.

It's the same company as well

...toyo roki and filtech. Oh I see what you are saying, the black Subaru OEM is made by Tokyo Roki, not Toyo Roki.
