This is my second time ordering from K&N and the second time that the service has been fantastic. Ordered Sunday and arrived Tuesday. As for the part itself, it's clearly well made. Much better standard than the Ford original. I bought this for my Focus ST TDCi, which I have a bluefin on and this just completes the package. The turbo seems to spool quicker and is able to reach higher pressure (seen through OBD readout), plus there's a great induction sound that boarders on chavy but i like it and I blast Killswitch... I think this is a great mod if you're just starting on your ST voyage as I am... Now just to cut down the mileage so I can get an RS... Thanks K&N
