11 common questions answered
Where is the engine air filter located on a 2018 Cadillac CTS?
The 2018 Cadillac CTS engine air filter sits in a sealed airbox on the driver side of the engine bay, just ahead of the 3.6L V6 intake.
This airbox location allows the filter to clean incoming air before it reaches the throttle body on your CTS’s V-configured six-cylinder. Access typically involves releasing the airbox clips and lifting the lid to remove the panel-style element. Visit Herb Chambers Cadillac of Lynnfield in Lynnfield, MA for OEM-spec replacements and proper housing re-seal.

Whats the difference between an engine air filter and a cabin air filter on a 2018 Cadillac CTS?
The engine air filter protects the 3.6L V6 by filtering intake air, while the cabin air filter cleans HVAC air for you and your passengers.
On the 2018 Cadillac CTS, the engine filter supports performance and fuel quality by trapping debris before airflow meets the mass airflow sensor and throttle body. The cabin filter, typically behind the glove box, captures dust and pollen to keep the interior fresh. Our Lynnfield service team installs genuine Cadillac filters for correct fit and seal.
