Bosch Engine Air Filter 5195WS Replacement for Ford/Mazda/Mercury — 98% Particle Capture, Low-Restriction Pleats

If your vehicle's air filter is clogged or aging, the engine must work harder, which can reduce fuel efficiency and accelerate component wear. The BOSCH 5195WS is built with many tightly arranged pleats and a high-velocity cellulose media designed to hold more debris while maintaining low airflow resistance. A durable polyurethane foam gasket seals the housing against contaminants, and the filter’s construction helps balance filtration performance with unrestricted air delivery to the engine.

How does this filter improve engine performance?

By trapping fine particles before they reach the intake, this Bosch unit helps preserve engine components and sustain consistent air delivery. Less contamination in the combustion chamber keeps sensors and moving parts cleaner, which supports more stable operation and can help maintain factory fuel economy.

• About 98% efficiency at removing small particles from incoming air.
• High pleat density increases particle holding capacity, extending service intervals.
• Low-resistance cellulose media maintains steady airflow under load.

What materials and design features matter in the 5195WS?

The filter combines cured cellulose media with an engineered pleat pattern for reliable filtration and even airflow. The polyurethane foam seal resists heat and moisture, ensuring the intake system stays protected even in varied driving conditions.

• High-velocity cellulose cured media for minimal air restriction.
• Even pleat spacing to optimize particle capture and airflow balance.
• Elastic polyurethane foam gasket to prevent air bypass and seal against contaminants.

Which vehicles is this Bosch filter compatible with?

This Workshop-series element fits a selection of Ford, Mazda, and Mercury models, but fitment depends on year, trim, and engine. Always verify compatibility using the vehicle fit checker before purchasing to ensure correct sizing and sealing.

• Ford: 2009–2012 Escape models (verify trim and engine).
• Mazda: 2009–2011 Tribute models (confirm fitment specifics).
• Mercury: 2009–2011 Mariner models (trim/engine dependent).

How do I know when to replace the filter?

Check the air filter at every oil change or according to your vehicle’s maintenance schedule. Replace it sooner if you drive in dusty or harsh environments, or if you notice decreased fuel economy, rough idling, or reduced throttle response.

• Inspect visually for heavy dirt, oil, or torn media at each oil change.
• Replace immediately if pleats are clogged or the foam seal is damaged.
• Use a new Bosch 5195WS to restore filtration efficiency and airflow.

Who is this for: The BOSCH 5195WS is aimed at owners and technicians who want a dependable, workshop-grade replacement air filter for select Ford, Mazda, and Mercury vehicles. It’s a practical choice for drivers seeking a balance of high particle capture and low airflow resistance—especially useful for those who regularly service their own cars or rely on professional maintenance to preserve engine life and efficiency.
