Bosch Engine Air Filter 5195WS for Ford/Mazda/Mercury - 98% Particle Efficiency, Foam Seal

BOSCH 5195WS is a workshop-grade engine air filter engineered to trap up to 98% of small incoming particles, protecting the intake and helping maintain engine performance.

Replacing a clogged or worn air filter is one of the simplest ways to help your engine breathe correctly. The Bosch 5195WS uses tightly packed pleated media and a resilient foam seal to remove fine dust and debris while preserving airflow. Designed for aftermarket workshop service, it’s built to meet the demands of routine maintenance and to fit specific Ford, Mazda and Mercury applications — always confirm fitment for your exact trim and engine.

How does this filter protect the engine during everyday driving?

The filter captures dirt and particulates before they reach sensitive engine components, reducing abrasive wear on cylinders and valves. By keeping contaminants out of the intake, it helps preserve internal parts and may support more consistent combustion over time.

• 98% efficiency at filtering small particles.
• High pleat count increases dust-holding capacity.
• Polyurethane foam lip reduces the risk of unfiltered air bypass.
• Even pleat spacing maintains consistent filtration across the media.

Will this filter affect airflow and fuel efficiency?

The Bosch 5195WS balances filtration with minimal resistance by using a high-velocity cellulose media. That media allows sufficient airflow for proper engine function while still removing fine contaminants, which helps the engine run efficiently under normal conditions.

• Low-resistance media for steady airflow.
• Media cured for structural stability at higher intake velocities.
• Even pleat spacing prevents choke points that reduce flow.

How durable is the seal and construction for workshop use?

The filter’s construction focuses on longevity under varying temperatures and moisture exposure typically encountered in engine bays. The polyurethane foam seal offers elasticity to maintain a tight fit and reduces the chance of water or heat breaching the intake system.

• Elastic foam seal resists compression set over time.
• Media curing improves dimensional stability in heat.
• Robust pleat design holds dust without collapsing prematurely.

Which vehicles will this part fit and how do I confirm compatibility?

Bosch lists the 5195WS as compatible with certain model years of Ford Escape, Mazda Tribute, and Mercury Mariner, but fitment can vary by engine and trim. Always verify with your VIN or the store fitment checker before purchase to ensure a correct match.

• Common listed matches: Ford Escape (2009–2012), Mazda Tribute (2009–2011), Mercury Mariner (2009–2011).
• Trim level or engine size may change compatibility.
• Use VIN-based lookup or compare the old filter’s shape and dimensions.

Who is this for: The Bosch 5195WS is aimed at DIYers, independent mechanics, and service shops that need a reliable replacement engine air filter for compatible Ford, Mazda or Mercury vehicles. If you want a workshop-quality part that emphasizes particulate capture while maintaining airflow, and you verify model fitment beforehand, this filter is a practical choice for routine maintenance and engine protection.
