Guys (and Gals), I've been an F-16 Fuels mech for some time now. Look at the two filters. They both have the same diameter inlet holes, and the same diameter outlet holes. As far as decreased oil pressure is concerned, the same bypass relief spring (at the top of the filter) is in both filters, which would produce equal flow pressure. One HUGE advantage to the larger filter is MORE FILTERING MEDIA, which can trap more dirt and other contaminants in the oil before getting clogged, in which case bypassing oil (ie: not filtering it). The only other difference is that the larger one has more capacity, which is good. Given that, more oil capacity equals somewhat lower oil temp (bigger filter to disperse more heat), plus more oil in which to disperse contaminants. Honda has officially "ok'd" the use of the larger filters on all new Honda Civics (I use one on my 2003 HX with 15,000mi on it).:huh:
