Description
The Ramair Foam 70–90mm Cone Air Filter is a versatile, high-performance universal filter designed to improve intake airflow and deliver superior filtration. Built to fit securely onto the outside of rigid pipes such as MAF sensor housings, it is ideal for both standard and performance applications.
Equipped with a rubber polymer base neck and a cone-shaped filter element, this filter ensures a tight, reliable fit while maximizing surface area for optimal airflow. Its compact form allows for installation in space-restricted engine compartments without compromising performance.
This filter includes four reducing rings, allowing the inlet to adapt from 90mm down to 85mm, 80mm, 75mm, or 70mm. This flexibility ensures compatibility with a wide range of intake systems, making it an excellent choice for universal fitment and custom setups.
Internally, the filter incorporates a stainless steel cage for strength and durability, combined with Ramair’s famous 15mm twin-layer foam. This advanced filtration media effectively captures dust and contaminants while maintaining unrestricted airflow, resulting in sharper throttle response, improved efficiency, and long service life.
Proudly manufactured in the UK, Ramair universal filters are available in many different sizes and styles to suit diverse applications. Reusable and easy to maintain, the filter can be cleaned and restored with the Ramair CK-003 Filter Maintenance Kit.
