Follow these steps carefully
Open the hood and find the black plastic air cleaner case. The ADX's 1.5L turbo is from the same L15 engine family as the Integra and shares the airbox design with the 2022+ Civic 1.5T.
The lid is held by metal clips along one edge — press each clip downward with your thumb until it releases and folds out of the way. No tools needed; the clips are made for fingers. Free every clip before moving the lid.
With the clips released, push the cover toward the passenger side. Plastic locating feet on the far edge hook into the lower half — sliding sideways frees them, then the lid lifts straight off. Don't pry straight up against those feet; that's how they snap.
Pull the old panel filter out. Note the airflow arrow on its side — the new filter must point the same way. While the box is open, glance at the intake hose connection for cracks or a loose clamp.
Vacuum or wipe the lower half of the housing. Sand, leaves, and grit settle into the bottom of the tray, and clearing them out keeps the new filter from loading up on its first day of work.
Drop the new filter in with its airflow arrow matching the old one's direction. Press it down evenly so the rubber sealing edge sits flat all around — a corner that rides up breaks the seal.
Set the lid back on, hook the plastic feet into their slots, slide the cover back toward the driver’s side, and flip each metal clip up over the lip until it catches. Start the engine — the idle should be smooth, with no whistle from the intake and no warning lights on the dash. Acura’s Maintenance Minder flags the air cleaner element under service sub-code 2, so only reset the minder once the job is genuinely done.
My two cents on this step: Only reset that Maintenance Minder sub-code 2 after the filter is actually in — resetting it mid-job is how the car ends up thinking the filter was changed when it wasn't.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
