2020 Lexus RX 450h Air Filter in Smyrna, GA

The engine air filter sits inside a rectangular air box in the engine bay, typically secured with clips or screws near the intake duct.

This location allows the filter to clean incoming air before it reaches the RX 450h’s 3.5L V6 hybrid intake. In Smyrna, GA, dust, road debris, and pollen can accumulate around the air box, so periodic checks are smart. Nalley Lexus Smyrna can inspect the housing seal and intake pathway during a routine visit.

• Air box: hard plastic housing near the front/side of engine bay
• Access: release clips/screws, lift lid, swap filter
• Inspection: check intake ducting and seal for debris or gaps

The engine air filter cleans air for combustion; the cabin air filter cleans air for passengers through the HVAC system.
