Dinan Air Filter - BMW 540i 2017-2023

This replacement air filter is built for Dinan's High Flow Carbon Fiber Intake systems (D760-0056 and D760-0068), with custom molded ends that maximize filter surface area inside the Dinan air box. Deep, multi layered cotton pleats increase airflow while maintaining strong filtration, and an internal steel wire mesh adds strength and dent resistance.
