no, no con... (if you change filters every 10'000km)

just higher oil pressure...

so whats the gain of higher oil pressure ??

how do these compare to standard honda ones ?

so whats the gains of using the hamp filter over the honda one ?

this does not concur with my personal experience...

but this is with a oil cooler and oil filter relocation kit.

apparently (and in my own experience) smaller filters increase oil pressure and oil pressure consistency...

i am using one now, as i believe that it improves oil pressure (as it is smaller)

eh?
all honda filters are the same bar the nsx and some other v6 hondas.

prelude
teg
civics
s2k
crv
euro
accords.
practically use all the same oil filters.

The stock oil pump pressure relief valve keeps the oil pump from producing excess oil pressure no matter what volume the pump is pumping into and it's set at the factory oil filter volume has no effect on the valve.

The pressure relief valve inside the filter they are discussing in your links is just internally to the filter and the valve opens when the filter is TOO CLOGGED to continue operating safely inside it's burst rating it is NOT controlling engine oil pressure it is just determining which path the oil takes inside the filter, like normal operation with unclogged filter or bypass the filter element when the filter is clogged only.

so why, when i fitted a smaller K20A oil filter to my system, did the oil pressure increase?

so what is the 15400-PLC-004 oil filter?

i went from:

a Ht=75mm Dia=84mm size oil filter:

to a Ht=85mm Dia=69mm size oil filter:

http://image.racepages.com/live/A6000116609OES.JPG

and my oil pressure increased?

was this a coincidence?

if so, why did my oil pressure decrease after i went back to the original sized one?

PLC was the older one.
RTA is the newer one.

both the same, just a diff part number.
same size and all.
PLC is made in jap
RTA is made in USA and jap, depending which batch it is.

so what is the top filter in the two pics i posted above?
