Step-by-Step Instructions
Follow these steps carefully
1
Prep and locate the air box
Park, set the parking brake, and shut the engine off. This is a mid-engine car -- the air filter lives under the rear deck behind the cabin. Open the rear decklid and find the airbox under the engine cover. Tools: T15 Torx bit, 8mm deep socket, clip puller, flathead screwdriver, vacuum, damp towel. Covers the Stingray 6.2L V8; the Z06 uses a different intake.
🔧 Mechanic's note — Tom Becker
The single biggest mistake I see is owners opening the front hood and hunting for the airbox -- on the C8 everything is behind you, under the rear deck, and the job only takes a few minutes once you know that.
2
Open the air filter housing
Pop the engine cover's push clips with a clip puller or flathead, then remove the airbox lid screws with the T15 Torx bit. Lift the lid slowly, keeping the gasket seated in its channel -- it must stay there for the box to seal. Tray the push clips; the bay uses several identical ones.
3
Remove the old filter and clean
Lift the old filter out and compare it with the new one. Vacuum the box bottom, wipe it with the damp towel, and keep grit out of the intake opening. The low rear intake ingests extra road spray and dust, so inspect more often than the manual's interval in wet or dusty conditions. GM: every 45,000 miles.
4
Install the new filter
Seat the new filter, rubber seal fully in the groove, matching the old orientation exactly. Press it flat with no raised corners -- it should drop in without force. Double-check the channel gasket is still seated evenly before the lid goes back on. Match every contour and the gasket profile against the old filter.
🔧 Mechanic's note — Ray Delgado
In my experience, Before the lid goes on, run a fingertip all the way around that channel gasket -- one corner that walked out while you were working will leave a gap you cannot see but will absolutely hear on the first drive.
5
Reseal and verify
Lower the airbox lid, reinstall the T15 screws, and snug them evenly -- firm is enough in plastic. Refit the engine cover and press each push clip back in until it seats. Close the rear decklid, start the engine, and idle a minute, listening for whistling from the rear.
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
