Follow these steps carefully
Park on level ground, shut the engine off, let it cool, and pop the hood. Identify the MAF sensor's electrical connector now, because it comes off before the lid.
On many Sonics — especially the 1.4L Turbo cars — the connector has a small red locking tab: slide the red tab back first, then squeeze the release and pull the connector straight off.
I replace one-time-use fasteners. Stretch bolts and torque-to-yield are single-use for a reason. My rule: if it doesn't fit, don't force it. Forcing breaks things; stepping back usually reveals the trick.
Back them all out with a T25 Torx socket and set them aside somewhere safe; they're small and love to drop into the engine bay. There's no need to disconnect the intake duct for a filter swap.
Lift the lid straight up off the housing and pull the old filter out, noting which way it faced. On 1.4L Turbo cars the lower box itself sits in three push-in mounts — if the whole base starts lifting with the lid, hold the base down with your other hand and lift just the lid. Don't let the lid hang from the MAF wiring; unplugging it first (step 2) is what gives you the slack.
Wipe the inside of the lower housing and the lid with a clean rag to clear dust and grit before the new element goes in.
Set the lid straight down on the housing and run all the T25 screws back in until snug — the screws thread into plastic, so don't overtighten or you'll strip them and the lid will never seal again. Then push the MAF connector back on until it clicks; if your connector has the red locking tab, slide it back into the locked position. A MAF plug that isn't fully seated is the number one cause of a check-engine light after this job.
Start the engine and check for a smooth idle, no whistle or sucking sound at the box, and no check-engine light. A CEL right after this job almost always means the MAF plug isn't fully seated or the red tab isn't locked — recheck those before anything else. The whole job takes a pro about 12 minutes; at home, inspect the element at each oil change and replace it per your owner's manual schedule, sooner if you drive dusty roads.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
