I really doubt that capacity is the issue unless you are running 20,000 mile oil changes with a badly tuned engine or cheap oil. Efficiency is more important if you want to reduce wear. Move to a synthetic like the P169071 which will take out 95% down to 7 microns instead of 20+ microns as in most filters.

I've read that its not good to use an oversized filter because it causes reduced oil pressure, reduced flow, and if you have a faulty adbv it takes longer for the filter to fill up and raise the oil pressure causing your engine to run dry longer. So whats the value of a larger filter?? More filter media area? Better cooling?

If you install any filter with out oil in it, it takes 2 seconds to fill. What you've read is nonsense, no offense intended. Oil pressure won't change, and flow through the engine won't change either. Flow through the filter will slow slightly, that's good. A faulty abdv? How often does that happen? With a good quality oil and filter, even an oversize one, you shouldn't have any worries. My 2¢

Gary, do you know if an oversize exists for the Purolator L24651 listed for a 5.0 Ford Explorer?
Yes and no. This uses the modular thread. You may have an oil cooler that sorta complicates it. I believe that the 4.0 OCH and 5.0 that use the modular thread actually have the old 3/4-16 thread adapted via the right angle mount (if used) otherwise, it's a stud with 3/4-16 block side threads and 22x1.5mm exterior threads. It it has a right angle mount w/o oil cooler, then you just get a right angle mount for a Chrokee for a lot less money ($40). If it's got an oil cooler, then the extension bolt for the cooler won't necessarily work depending on if it sits on the block side or the filter end of the right angle adapter.

He's talking about bulging the can. Bigger can ..more flex. Now if you're running one of these engines, I'd say follow this guy's advice. I'm sure that he found out that a bigger element made it harder to cope with.
