2019 Cadillac ATS Coupe Air Filter in Lynnfield, MA

The 2019 Cadillac ATS Coupe’s engine air filter sits inside a sealed airbox in the engine bay, ahead of the turbo inlet ducting.

This panel-style filter feeds the 2.0L turbocharged inline-4 and is accessed by releasing the airbox cover fasteners. Keep the mass airflow (MAF) sensor undisturbed and ensure the airbox lid seals evenly when reinstalled. If you prefer professional help in Lynnfield, our OEM-trained team can inspect and replace it during the same visit—just schedule service.

• Open the hood; locate the rectangular airbox connected to the intake snorkel.
• Release clips/fasteners, lift the lid, and remove the flat panel filter.
• Inspect for debris; seat the new OEM filter and close the lid evenly.

On a 2019 Cadillac ATS Coupe, the engine air filter cleans air entering the 2.0L turbo engine, while the cabin air filter cleans air entering the HVAC for passengers.
