2018 Mercedes-Benz SL-Class Air Filter in Lynnfield, MA

It’s housed inside a sealed airbox in the engine bay that feeds the twin‑turbo 3.0L V6.

The SL-Class’s intake airbox is designed to deliver clean, metered air to the turbochargers for consistent power and drivability. Access requires releasing the airbox cover clips and fitting an OEM-spec panel filter. If you prefer professional service, our Lynnfield team will install a genuine Mercedes-Benz filter and verify proper airbox sealing. Book a convenient schedule service appointment.

• Twin-turbo 3.0L V6 (362 hp, 369 lb-ft) benefits from unrestricted intake flow
• Airbox location: engine bay; access via airbox cover fasteners
• OEM filter ensures correct fit and filtration efficiency

It’s typically located behind the glove box, integrated with the HVAC housing.

This placement filters air entering the interior, reducing dust, pollen, and fine particulates for the two-seat cabin. Access may require trim removal to avoid damaging clips or seals. Our OEM-trained technicians can replace it cleanly and reset any service reminders while you take advantage of current service specials.

• Behind-glove-box HVAC slot for easy airflow path
• Protects occupants by filtering incoming outside air
• Professional replacement avoids trim or latch damage

The engine air filter cleans intake air for combustion, while the cabin air filter cleans HVAC air for passengers.

In your SL-Class, the engine filter protects the 3.0L V6 and turbochargers from debris that can reduce performance or efficiency. The cabin filter traps dust and allergens to keep interior air fresh. Both filters work best when replaced with genuine Mercedes-Benz elements that match factory airflow and sealing standards.

• Engine filter: safeguards turbos, MAF readings, and power delivery
• Cabin filter: improves HVAC airflow and in-cabin air quality
• Use OEM filters for proper fit, filtration, and longevity

Engine symptoms include reduced power and lower MPG; cabin symptoms include weak HVAC airflow and musty odors.

On the 3.0L twin‑turbo V6, restricted intake can feel like sluggish acceleration or rough idle. Inside the cabin, a dirty filter can limit airflow or add odors, especially in spring and fall pollen seasons. If you notice these changes, schedule a quick inspection and OEM replacement in Lynnfield.

• Performance: hesitation, rough idle, or audible intake strain
• Efficiency: decreased fuel economy over recent averages
• Cabin: reduced vent flow, dust buildup, or musty smell

Yes—engine filters are often DIY-friendly, but dealer service adds OEM parts, intake/MAF checks, and proper sealing.
