The engine filter cleans intake air for the 2.0L turbo engine, while the cabin filter cleans air for the HVAC system and passengers.

Both are essential but serve different systems. The engine air filter protects combustion components and helps the CT4 maintain smooth power delivery. The cabin filter targets comfort and health by trapping particulates before they enter the interior vents.

• Engine filter: performance and engine protection
• Cabin filter: interior air quality and HVAC efficiency
