Follow these steps carefully
The 2018–2023 Traverse Premier's (3.6L LGX V6) engine air filter sits in the airbox in the engine bay. You'll need: a new panel filter. The lid is clip-type (tool-free). Open the hood — the large black airbox is easy to spot in the roomy bay.
Release the clips on the airbox lid by hand — no tools needed. Lift the lid off; it may have the intake tube attached, so lift it just enough to access the filter. Don't force the clips.
Lift the old panel filter out and note its orientation. A dirty filter starves the 3.6L LGX and wastes fuel — on a heavy 3-row SUV, every MPG counts. Check the box for leaves and debris.
On the big GM V6s, a clogged air filter rarely throws a code — it just quietly costs you two or three MPG. If your Traverse's fuel economy has been sliding for months, this five-minute swap is the first thing I'd check.
Wipe the airbox clean and remove all dust, leaves, and debris. Check the seal is intact before the new filter goes in — and don't touch the MAF sensor.
Install the new panel filter in the same orientation, sitting flat and fully sealed. A good seal keeps the MAF reading correctly, which the LGX's fuel economy depends on.
Replace the lid and engage all clips for a tight seal, then close the hood. Start the engine — the 3.6L LGX should idle smoothly. Replace every 15,000–30,000 miles.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
