I would agree that a replacement filter would be close to zero on an EU car. The US cars are stuck with the charcoal layer built in their filters so there is a small gain. AA's dyno for their paper replacement, which looks a lot like a stock EU filter, was showing 5-7 hp differences over the US stock version.
