Manufactured in the USA, it is engineered to meet or exceed OE performance standards for extended service intervals.

Specifications include a primary (outer) radial-seal element for heavy-duty intake systems, designed for OptiAir-style housings. This element uses high-capacity cellulose media for superior dust-holding ability and consistent airflow.
