Designed for Efficiency, Life and Flow

A good air filter needs to do more than simply fit in the airbox.

Ryco designs its filters around three key areas:

• Efficiency – capturing harmful dust and airborne contaminants
• Life – holding dirt effectively over the service interval
• Flow – allowing the engine to breathe properly

This balance is especially important on turbocharged engines such as BMW’s B58 3.0-litre petrol engine, where clean and consistent airflow plays a key role in everyday drivability and performance.

Protects the Engine’s Air Intake System

Your engine’s air filter is the first line of defence against dust, dirt and airborne particles entering the intake system.

While the quality of engine oil is something you can control, the air entering the engine depends heavily on the condition of the air filter. A tired, blocked or poor-quality air filter can reduce airflow and allow more contaminants into the system.

Ryco air filters are developed using dedicated filtration testing procedures to help protect the engine without compromising airflow.
