MAF
or mass air flow sensors, can also be upgraded as needed, as long as your intake allows so, the PRO-M 70mm is the general favorite here. This mod is best left until fuel upgrades are required(larger injectors) and should be calibrated accordingly

intake manifolds
can also be upgraded or altered as needed. the popular bolt on upgrade for the 2.0 ZETEC is a swap for a year 2000 maniold, this year the intakes had round runners and yielded slightly more air flow. it is alos popular to port the runners of this befor the swap but little or no gains are yielded from doing so, the only part needing porting is the opening where the IM mates up to the throttle body when a larger TB is installed, this is correct procedure to port this opening prior install allowing full use of the added size of the TB.
other intake manifolds for this engine include

Ford Racing Intake Manifold: requires some machine work and SVT alternator bracket or grinding to fit ZETEC, but the best IMO

MCNEWS
