🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight to find the large black plastic air box connected to the intake tube (the big tube that feeds the engine).

Step 2: Open the air box

• Release the air box retaining clips by hand (most are metal spring clips).
• If the cover feels stuck, wiggle it gently by hand—don’t force it.
• Tip: Take a quick photo before opening.

Step 3: Remove the old air filter

• Lift the air box cover enough to slide the filter out.
• Pull the filter straight out and note how it sits (which side faces up and how the seal fits).

Step 4: Clean the air box (lightly)

• Use a clean shop towel to wipe out loose dust inside the lower air box.
• Use a small vacuum (shop vac) to remove debris from the bottom of the box.
• Do not let dirt fall into the intake opening.

Step 5: Install the new air filter

• Place the new filter into the lower air box in the same orientation as the old one.
• Make sure the rubber seal sits flat all the way around (no corners folded).
• Tip: If it won’t sit flat, it’s misaligned.

Step 6: Close and latch the air box

• Lower the air box cover back into place.
• Re-engage all clips by hand and verify the cover is evenly seated on all sides.

✅ After Repair

• Start your Expedition and let it idle for 15–30 seconds.
• Listen for any hissing/whistling near the air box (a sign the cover isn’t sealed).
• Recheck that all clips are fully latched and the cover is sitting evenly.
