2019 Chevrolet Blazer Air Filter in Murray, UT

It sits in the engine bay inside the intake airbox, typically on the driver’s side near the fresh-air duct.

The 2019 Chevrolet Blazer’s 2.5L inline-4 draws air through a panel-style filter housed in a rectangular black airbox. You’ll see clips or screws on the cover and a mass airflow (MAF) sensor plugged into the inlet tube. If you prefer a professional inspection, our Murray team can confirm condition and sealing during a quick visit.

• Rectangular airbox with metal clips or Torx screws
• MAF sensor mounted near the airbox inlet tube
• Easy top-access cover for filter inspection/replacement

The engine filter protects the 2.5L inline-4’s intake from dirt, while the cabin filter cleans HVAC air for passengers.

On the 2019 Chevrolet Blazer, the engine air filter preserves performance and fuel economy by keeping debris out of the intake and throttle body. The cabin filter, usually behind the glove box, removes dust, pollen, and road odors from air entering the interior. Both are serviceable items that support comfort and reliability across Utah’s changing seasons.

• Engine filter = combustion air; cabin filter = passenger/HVAC air
• Engine filter lives in the under-hood airbox; cabin filter is inside the dash
• Both require periodic inspection and replacement

Reduced power, lower mpg, and rough idle point to an engine filter issue; weak airflow and musty odors suggest a cabin filter problem.
