Product Description

The K&N RU-1760 is a universal clamp-on air filter with a 20-degree angled flange, designed to mount directly onto a carburetor throat or intake neck that isn't perfectly straight. With a 2.438 in. flange diameter and 5 in. overall height, it's built for custom carbureted setups, racing applications, and small engines where intake geometry calls for an angled connection.

Built from four layers of cotton gauze treated with K&N's tacking agent, the RU-1760 is engineered to trap contaminants while supporting strong airflow for a boost in horsepower and acceleration. The pliable rubber flange absorbs vibration for a secure hold and can stretch slightly to accommodate intake necks that fall between standard sizes.

This filter is a good fit for builders and enthusiasts working on carbureted engines or custom intake setups where the intake neck sits at an angle rather than straight on. It's also compatible with aftermarket silicone pre-filter covers sized to its exact dimensions, making it a practical choice for off-road or dusty environments where added dust and moisture protection matters. Since it's a clamp-on universal filter, match your carburetor throat's outside diameter to the filter's flange and confirm the 20-degree angle suits your intake orientation before ordering.
