What Does It Do?

The Ramair Performance Panel Filter range is designed to replace your standard OEM paper air filter, delivering improved airflow, better filtration, and enhanced engine performance.

The Pleated Nanofibre filter uses advanced synthetic nanofiber media, carefully pleated to maximise surface area, increasing airflow while maintaining excellent filtration. Developed using over 35 years of motorsport experience, it’s an ideal choice for fast road and track applications.

The Twin Layer Foam filter is manufactured from Ramair’s unique Aeriform foam, featuring a fully reticulated dual-layer structure that delivers exceptional dust filtration and consistent airflow. Supported by a stainless steel cage (used in top-tier motorsport), it ensures durability and long-lasting performance.

Both options offer a simple drop-in upgrade, combining performance, protection, and reusability for your vehicle.
