2021 Honda Passport Air Filter in Burlington, MA

The 2021 Honda Passport’s engine air filter sits inside the engine-bay airbox feeding the 3.5L V6 intake.

This sealed airbox is typically mounted near the front corner of the bay, upstream of the intake duct and MAF sensor. Access involves unclipping or unscrewing the cover to swap the filter. During service, our technicians also check the airbox seal and intake plumbing for debris or gaps that can admit unfiltered air on Burlington, MA roads.

• Housed in the primary engine airbox
• Upstream of the intake duct/MAF sensor
• Lid fasteners or clips secure the panel filter

The engine air filter protects the 3.5L V6’s intake, while the cabin air filter cleans HVAC air for passengers.

The engine filter prevents dust from entering the V6 (280 hp) to help preserve performance and fuel economy. The cabin filter, typically a particulate or activated-carbon element, traps pollen and road dust before air reaches the vents. Replacing both on schedule supports smooth drivability and cleaner air during commutes around Burlington, MA.

• Engine filter = combustion protection
• Cabin filter = HVAC/passenger air quality
• Both are serviceable components

Four clear signs are reduced power, lower fuel economy, rough idle, and weak or musty HVAC airflow.

When the engine filter is restricted, the V6 can feel sluggish and consume more fuel. A dirty cabin filter leads to weaker airflow and possible odors from trapped debris. If you notice these symptoms in your 2021 Honda Passport, a quick check at Herb Chambers Honda of Burlington can confirm whether filters need replacement.

• Slower acceleration or throttle response
• MPG drop compared with normal
• HVAC airflow weak or musty

Yes—the engine filter is often DIY-friendly, but dealer service adds OEM-spec parts and intake/MAF inspections.

Many owners can open the airbox and swap the engine panel filter at home. Cabin filters may require glovebox removal and careful reassembly to avoid rattles or airflow leaks.
