Are there performance fuel filters for the EF that are that will do a better job than a standard one, and if so are they pricey?

Dare I ask why? Even if there was a high flow filter avaliable why would you want it? I would of thought that the flow rate on the standard filter is higher than the flow rate on the standard injectors or pump!
Just buy a decent brand fuel filter like Ryco and you should be fine. But I'm asssuming here that you have little engine work.

As twr7cx said there isn't any need for a performance fuel filter, the stock one easly flows 255l/hr which is about 3x the flow rate of the fuel pump. Just use a ryco or similar filter from any auto store.

Ryco Z373 aluminium filter. Best by far. You dont need as much torque on the fittings to the filter because the aluminium filter seals better than the steel ones, therefore you wont end up rounding the fittings.
