my *problem* was that once i installed the 19 row oil cooler, the oil cooler lines, the oil filter reolocator, my peak oil pressure dropped to 70-75PSI above 3000rpm... wheras it sat on 80-82PSI prior to the installation.
by fitting the newer smalll type of oil filter, i improved it back upto around 79-80PSI peak oil pressure.
the first one, must be a old type honda filter.
the newer ones is like the bottom. small, it's been the small one for at least 4 years now.
well, compared to the "old type honda filter", the "new small type" improves oil pressure.
and FYI - if you buy a oil filter for a pre 2000 Honda at most auto parts stores, you get a Z79A or equiv. from the dude behind the counter, which is the "old type honda filter"...
