The Bosch 5161WS Workshop Engine Air Filter delivers professional-grade filtration performance designed to protect your engine from wear-inducing particles. Engineered with 98% filtration efficiency, this filter removes small particles from incoming air to guard against engine wear while maintaining optimal airflow for strong engine performance.

Key Features:

• High number of pleats for robust particle holding capacity
• High velocity cellulose cured media provides minimum air resistance and ensures even pleat distance for optimum efficiency
• Polyurethane foam seal provides elasticity and sealing performance, while protecting against water and heat intrusion
• Non-oiled design provides the same efficiency as an oiled air filter while protecting the air mass sensor
• Panel-style design with white paper filter media

These features combine to provide optimal performance and fuel efficiency for your vehicle in all driving conditions. The precision-engineered polyurethane seal ensures proper fitment without loss of filter surface area, maximizing filtration efficiency throughout the filter's service life.
