Carquest Premium Conical-Shaped Radial Seal Inner Air Element ensures clean air delivery to protect engine performance and longevity. Designed as a secondary (safety) filter, it captures remaining contaminants not caught by the primary outer filter, safeguarding engines from harmful dust and debris. Built to meet or exceed OE performance standards, it provides consistent protection in heavy-duty environments. Proudly made in the USA, this inner filter is engineered for durability and reliable sealing. Specifications include a conical-shaped radial-seal design with inboard seal, intended as a secondary filter element that mates with the corresponding primary outer filter. This filter is designed to fit inside Carquest 88870 and 93656 as part of paired radial-seal sets.
