Hi,
Yes Ryco charge close to price from Jeep. Seemed to be similar quality. Interesting that wesfil also quote Audi and Mazda application for same filter.
The Wesfil WZ596 was around $13 if my memory isn't broken. I wanted scientific test :D on quality so I held them up and... Wesfil didn't feel as "heavy" as Factory Jeep one.
The wesfil air filter looks as good if not better than Jeep. Has the paper and foam two stages same as Jeep, also has steel mesh etc etc.
I think fuel filter on Jeep IS a Raycor 230 series assembly ( to be confirmed at next fuel filter change ) so Raycor R20S filter must be as good as factory, no?
Jeep charged me $115 last time for this, Raycor is $49 and includes the gasket and O ring same as Jeep. This is roughly exchange rate translation of Parker Hannafin's ( Raycor ) list price in the US so seems a fair price.
Check out these sites for fuel filter details

In the "spin on" section look up the 215/230/245 series in the pdf file for pics, ratings part numbers etc etc.
Cheers
