Gentlemen,
is the setting and size of a bypass valve important? Or is it just "randomly" set by the manufacturer?
The Oilfilter from Honda for the S2000, part Number 15400-PCX-004 has a bigger sized bypass valve (20 mm / 3/4" Diameter) and the spring is stiffer than usuall. The S2000 Engine have a little bit higher than usuall Oil pressure, up to 7 Bar / 100 PSI.
Here is a comparison of some filters, including the Bypass Valve:
Aftermarket filters mostly have smaller sized bypass valves, most are in the 10mm / 3/8" diameter range.
Some people say the setting of the spring and size is not important, some peoply say it is highly important.
I am a little bit confused.

3 oil filters compared - S2KI Honda S2000 Forums
S2000 Talk - 3 oil filters compared - Well, i got my snazzy oil filter cutter, and opened 3 filters in my garage: 1) A Honda 15400-PT7-005 (Fram?) 2) A Honda 15400-PCX-004 (current S2000 filter) 3) A Denso 150-1006 sold on a Honda parts site as better than the cheap Fram filter Honda is selling...
