Honda S2000/PCX filter- bad for other engines?

[vinu_neuro]

In the Honda 4cyl community it's very common for people to use the S2000 filter because it's made by Toyo Roki and is larger than the standard Honda filter size.

I came across specs in the various model service manuals and am wondering if maybe relief oil pressure settings are the reason for different filter sizes.

-F20/22c oil pressure: 36psi (idle) and 85psi (3000rpm).

-B and H have 10psi and 50psi. K is 10psi and 44psi.

-All have oil pump flow rate of ~62 qt/min, except K (57.4 qt/min)

So could the big oil pressure difference be why S2000 engines can run a larger filter since they can handle the pressure drop? I'm curious to know what oil pressures people get with the PCX filter on B/H/K engines.

Hi, I am one of those s2000 oil filter. The PCX-004 filter is no longer made by the Toyo Roki plant in Japan, The filter is made by Honeywell (i think) in the USA.

I like to use honda OEM parts as much as possible. But the new recommend oil filters for ALL honda engines are now a very tiny filter. Honda claims that the smaller filter actually raises the oil pressure by 5PSI.

The reason I choose to run the s2000 filter on my 2001 GS-R is the larger filter media capacity, and the fact that is not simply a rebranded FRAM filter like the new tiny honda OEM filters are. They have cardboard and sloppy filter media seatings.

I noticed no difference in performance, sound, oil temp. Between runing the filters.

Correction: 15400 PCX 004 is made by Filtech, a USA branch of Toyo Roki. And the filter flows better than the recommended tiny ones.

Same filter I ran on all my Honda B-series engines. Never had any issues.

Hummm ... I doubt that, and would like to know how that's possible with a positive displacement oil pump with the oil sensor (most likely) located after the oil filter.

That's quoted direct from my Honda dealers head master mechanic. I found it odd too. Still didn't convince me to switch to the tiny cans.

I have used the 15400 PCX-004 filter for over 7 years on my S2000. It is a quality filter (Toyo Roki and Filtec). I don't know why it is recommended only for the S2000, but many have speculated. It has a decent silicone ADBV, a reasonably stiff differential pressure spring, and it certainly is larger than the other Honda filters. The can itself is rather sturdy too. Why the singular application? I really don't know, but Honda seemed to think that the S2000 needed a different filter around 2003. Thus, the PCX-004 filter.

I have a '06 S2000 and I like to use the biggest filter that I can fit on the car and for my S2000 that is a Baldwin B7042. It's almost twice as big as the stock filter for the S2000.
