You have to watch out for the term SOHC (single overhead cam) which refers to the SPI engine in the base model sedans/wagons. The Zetec is DOHC (dual overhead cam).

Also from the links you posted, the first one was a short ram style intake and the second is a cold air intake (CAI). The short intakes are just an elbow off your throttle body, a pipe, and then a cone filter. The CAI unit runs piping all the way down and around the engine to hang the filter closer to the ground and the front bumper. The advantage of the CAI is that it isnt pulling the hot engine-bay air into the intake, disadvantages include driving through a deep puddle, sucking up water and hydrolocking your engine.
