2020 Cadillac CT5 Air Filter in Lynnfield, MA

The 2020 Cadillac CT5 engine air filter sits in a sealed airbox on the driver side of the engine bay, ahead of the 2.0L turbo intake.

This location allows filtered outside air to feed the inline-four before the mass airflow sensor. The cabin air filter is separate and typically sits behind the glove box, filtering air for passengers. Visit us at 395 Broadway (Route 1 North), Lynnfield, MA for quick access and OEM fitment.

• Engine: 2.0L turbocharged inline-4 (engine code 4ITCG2.0)
• Cabin filter: usually accessed behind the glove box
• Use Genuine Cadillac filters for proper sealing and flow

The engine air filter protects the 2.0L turbo’s intake from dirt, while the cabin air filter cleans air entering the CT5’s HVAC for passengers.

The engine filter preserves performance and helps maintain fuel economy by keeping debris out of the intake and MAF sensor. The cabin filter traps dust and allergens to improve in-cabin air quality. For both, we install Genuine Cadillac filters at Herb Chambers Cadillac of Lynnfield.
