Description
The Ramair Foam 70–90mm (2.75–3.5") ID Cone Air Filter with Reducing Rings is a versatile, high-performance universal air filter designed to optimize airflow while providing superior filtration. Engineered to fit securely onto the outside of rigid pipes such as MAF sensor housings, this filter is perfect for a wide range of automotive applications, including performance upgrades and custom intake systems.
Featuring a durable rubber polymer neck and a cone-shaped filter element, this design allows for easy installation in space-restricted engine compartments while maximizing filtration surface area. The internal stainless steel cage reinforces the structure, and Ramair’s 15mm thick twin-layer foam efficiently captures dust and debris without restricting airflow.
This model includes four reducing rings, enabling the filter to adapt to inlets of 90mm, 85mm, 80mm, 75mm, or 70mm, making it highly adaptable for multiple fitment requirements. Proudly manufactured in the UK, the filter is reusable and can be cleaned and restored using the Ramair Filter Maintenance Kit (CK-003).
