Why Replace Your Mercedes Benz Air Filter Set?

A restricted air filter doesn’t just reduce airflow—it disrupts the entire combustion process:

• Turbo works harder → reduced lifespan

• Fuel burns inefficiently → higher consumption

• Engine response drops → sluggish performance

Replacing both filters restores:

• Proper air intake balance

• Efficient turbo operation

• Factory-level engine performance

Recommended Service Interval

• 10,000 – 15,000 km (Kenyan driving conditions)

• Earlier in dusty or off-road environments

What’s Included

• 1 × Febi 49667 (Left Air Filter)

• 1 × Febi 49668 (Right Air Filter)

Professional Insight

For OM642 engines, replacing only one side is a false economy. Uneven airflow can lead to:

• Air mass sensor inconsistencies

• Turbo imbalance

• Reduced efficiency

Always replace as a complete set—which is exactly what this product delivers.
