A SRI or CAI is your best bet, not just for performance but for overall value for your Focus. I have/had the FocusSport CAI on my 2007 and it's quite the intake indeed! They've measured 8-10WHP on average for 2.0L Duratecs in the US and 8-12 WHP for 2.3L Duratecs in the US when you bolt on the FS CAI.
Due to where the CAI positions the filter (above the plastic "undershield" and behind the driver's foglight), hydrolocking the car is almost impossible unless you were to submerge that portion of the front clip entirely under water with the engine running. I don't recall the engine stumbling once due to moisture with the CAI and I ran it through a LOT of heavy rain and such.
