Follow these steps carefully
Pop the hood from the driver's kick panel lever and move to the driver's side of the engine bay. The air filter lives inside the big black plastic airbox mounted against the driver's-side fender.
On a Fiesta ST, the lid instead uses four Phillips screws plus a clamp on the intake hose — loosen the hose clamp with a flathead and disconnect the MAF sensor by pulling up its red lock tab first.
Work the lid up off the bottom half of the box. It may feel glued on by the rubber seal — rock it gently instead of prying with a screwdriver, which can crack the plastic. Before you touch the filter, notice how it lies in the tray: which way the pleats run, and how the rubber edge tucks into the rim of the lower box.
Lift the old panel filter straight out. Wipe the inside of the lower airbox with a dry shop rag and pick out any leaves or sand.
Set the new panel filter into the lower box exactly the way the old one sat, pleats facing down into the tray and the rubber gasket flat against the rim of the box. If it will not sit flush, you have it backwards or wedged — do not force the lid down to make it fit.
I've fixed the damage from skipping this: If it will not sit flush, you have it backwards or wedged; do not force the lid down to make it fit.
Here is the Fiesta-specific part: the lid has small tabs along one edge that must hook into slots on the lower box before you push it down. Slide the tabs in first, then lay the lid flat so the seal meets the filter all the way around. Thread the four bolts back in by hand first (that stops cross-threading), then snug them with the 8mm socket — firm is enough, the plastic strips easily. On the ST, re-tighten the intake hose clamp, reconnect the MAF sensor, and push the red lock tab back down until it clicks.
I've been burned by this before: Thread the four bolts back in by hand first (that stops cross-threading), then snug them with the 8mm socket — firm is enough, the plastic strips easily.
Close the hood, start the engine, and let it idle for about a minute. Watch the dash for a check-engine light — on ST cars that means the MAF sensor did not get plugged back in. Take a short drive and note the throttle response.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
