RU5135 High-Flow Cone Air Filter 70mm Flange – Oiled Cotton Gauze | Bowei Factory

The RU5135 high-flow cone air filter is designed for engines requiring a compact, efficient intake system with a 70 mm (2.75 in) flange connection.
Bowei produces the RU5135 using multi-layer oiled cotton gauze, offering higher airflow and better dust capture than standard paper filters commonly used by other suppliers.

The filter can be washed, re-oiled, and reused, making it a durable and cost-effective upgrade for performance vehicles or custom intake setups.
Its tapered cone design smooths airflow into the intake tube, while the molded rubber flange ensures a secure and vibration-resistant seal.

Built with strict QC standards, the RU5135 delivers stable filtration efficiency and long service life in demanding environments.
