2014 Lexus IS 350 C Air Filter

The 2014 Lexus IS 350 C engine air filter sits inside the airbox in the engine bay on the intake side.

Lift the hood and look for a rectangular plastic housing connected to the intake ducting; that’s the airbox containing your V6’s filter. Access typically involves releasing a few clips or screws to open the lid. Keeping this filter clean helps your 3.5L V6 maintain smooth airflow and consistent throttle response, especially in North Texas dust and pollen.

• Airbox is in the engine compartment on the intake side
• Access usually via clips or screws on the airbox lid
• Supports proper airflow for the 3.5L V6 (306 hp)

The 2014 Lexus IS 350 C cabin air filter is typically located behind the glove box in the HVAC intake.

On most IS models, you’ll remove or lower the glove box to access a small panel covering the cabin filter tray. This filter cleans air entering the passenger compartment, reducing dust and allergens during heavy North Texas pollen seasons. Gentle handling prevents bending the pleats and maintains even airflow across the A/C evaporator.

• Access panel is usually behind or above the glove box
• Protects HVAC system and cabin air quality
• Replace carefully to keep pleats straight and sealed

The engine air filter feeds clean air to the V6 for combustion, while the cabin air filter cleans air for you and your passengers.

Under-hood, the engine filter protects the intake, mass airflow sensor, and cylinders from dust that can reduce power and efficiency. Inside, the cabin filter screens pollen and particulates entering through the HVAC system. Both matter: one preserves performance; the other preserves comfort and health in your convertible’s interior.

• Engine filter: in airbox; protects intake and combustion
• Cabin filter: behind glove box; protects HVAC and air quality
• Both reduce wear, odors, and performance loss

Common signs include reduced power, poorer fuel economy, rough idle (engine filter), and weak airflow or musty odor (cabin filter).

If your IS 350 C feels sluggish or idles unevenly, restricted intake airflow could be the cause. Inside the cabin, diminished fan output or a stale smell signals a saturated cabin filter. North Texas dust and seasonal pollen can load both filters faster, so visual checks help prevent drivability and comfort issues.

• Engine: hesitation, lower MPG, unusual intake noise
• Cabin: reduced A/C airflow, odors, foggy windows
• Inspect for dark, debris-filled filter media

Yes—engine filters are often DIY-friendly, while cabin filters may require glove box removal and careful reassembly.

Many owners can swap the engine filter at home by opening the airbox and ensuring the seal is seated. Cabin filters typically sit behind the glove box and benefit from careful trim handling to avoid fitment gaps or rattles. Dealer service adds an intake/MAF inspection and confirmation that OEM-spec filtration is used.

• DIY engine filter: basic tools and careful sealing
• Cabin filter: glove box access; avoid bent pleats
• Dealer adds MAF/intake checks and OEM-spec parts
