Step-by-Step Instructions

Follow these steps carefully

Prep and locate the air box

Park on level ground, set the parking brake, and shut off the engine. Open the hood and find the sealed airbox upstream of the intake ducting — the big 12.6-inch panel (GM 84121217), shared with Silverado, Yukon, and Tahoe.

Open the air filter housing

Check whether your lid uses clips or screws — many need a screwdriver. Lift the lid only as far as needed, keeping it tethered so it doesn't strain the intake tube. Note the lid's orientation for reinstallation.

Remove the old filter and clean

Lift the filter. Panel options: GM 84121217, ACDelco A3244C, FRAM CA12404 (12.6 x 9.65 x 2.40 in). Hold it to light — no light through the pleats means overdue. Wipe the airbox, keeping debris out of the intake.

🔧 Mechanic's note — Ray Delgado

In my experience, If you run dirt roads, check this filter at every oil change — the T1's big 12.6-inch panel looks like it should last forever, but fine dust plugs it fast and you lose mileage before you notice.

Install the new filter

Seat the new filter with the rubber seal fully in the groove, pleats facing as the old filter did. Finger-check the perimeter — no gaps. An unseated filter lets dirt into the 5.3L/6.2L V8, causing premature wear.

Reseal and verify

Close the lid evenly so the seal compresses uniformly, then refasten every clip or screw. Snug the intake tube clamps. Start the engine and listen 30 seconds — whistling means an air leak. Test drive. Interval: 15,000–30,000 miles.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Installing the filter upside down or unseated so unfiltered air bypasses the element
• Leaving debris in the housing that then gets sucked into the intake
• Forcing clips/screws and cracking the plastic air box lid
• Reusing a heavily clogged filter instead of replacing it
