G4 Performance Pleated Air Filter

Improve airflow and filtration efficiency with this Ramair performance panel air filter, designed as a direct replacement for the factory air filter fitted to a wide range of Volkswagen Group vehicles on the 1J platform, including the Golf Mk4, Bora and New Beetle.

Manufactured using high-flow synthetic nanofibre filtration media, this filter improves airflow compared with restrictive factory paper filters while maintaining excellent filtration performance. The pleated design maximises filtration surface area, allowing more air to reach the engine while protecting it from contaminants.

Unlike disposable paper filters, this Ramair filter is reusable and washable, meaning it can be cleaned using the Ramair filter maintenance kit (CK-003) and reused for long-term performance and cost savings.

With more than 35 years of motorsport filtration experience, Ramair’s pleated nanofibre filter range provides a premium airflow upgrade for both standard and performance vehicles.

What This Filter Does

Standard paper air filters can restrict airflow, particularly as they become dirty or when the engine requires higher air demand.

This Ramair performance filter improves airflow by using:

• High-flow synthetic nanofibre filtration media

• Pleated construction to maximise filtration surface area

• Precision injection-moulded frame for an exact OEM airbox fit

This allows the engine to breathe more efficiently while maintaining excellent filtration protection.
