2021 Lexus RC 300 Air Filter in Smyrna, GA

The 2021 Lexus RC 300 engine air filter sits in a sealed airbox within the engine bay, ahead of the V6 intake tract.

The airbox opens to access a flat panel filter that feeds the 3.5‑liter V6 intake. This location protects the filter from heat and debris while ensuring steady airflow. If you’re unsure, our technicians in Smyrna can verify fitment and seal integrity during a quick inspection. You can schedule service online for a precise check.

• Access is under the hood at the airbox housing
• Filter is a flat panel style for the V6 intake
• Airbox clips or screws secure the cover

The 2021 Lexus RC 300 cabin air filter is typically located behind the glove box in the HVAC intake.

Most Lexus coupe applications place the cabin filter behind the glove box for easy access while safeguarding the blower motor. This filter screens pollen, dust, and road particulates before air reaches the cabin. If removal requires trim manipulation, our team can handle it cleanly and reset the glove box stops. Check our service specials before booking.

• Behind-glove-box access on most Lexus models
• Protects HVAC evaporator and blower
• Quick inspection during routine service

The engine air filter protects the V6’s intake system, while the cabin air filter cleans the HVAC air you and your passengers breathe.

On the 2021 Lexus RC 300, the engine filter sits in the airbox to keep dirt from entering the 3.5‑liter V6, helping preserve performance and fuel economy. The cabin filter sits in the HVAC path to remove dust and pollen. Nalley Lexus Smyrna installs Lexus Genuine filters matched to this model. Use our schedule service tool to book.

During a 2021 Lexus RC 300 air filter service, our technicians handle both airflow systems methodically. We begin with a visual inspection of the engine airbox, ducts, and intake snorkel, checking seals and debris. Next, we remove and inspect the engine filter and install a Lexus Genuine replacement if needed, ensuring the airbox closes evenly for a proper seal. For the cabin filter, we access the HVAC intake (typically behind the glove box), verify airflow direction arrows, and seat a Lexus Genuine cabin filter correctly to minimize bypass.

Before returning your RC 300, we perform a visual MAF/intake check, clear any loose debris, and confirm smooth fan output from the HVAC registers. If you’re aligning multiple services, our online scheduler makes it easy to coordinate a single visit.
