Dinan High Flow Drop-in Replacement Air Filter - 2016-2024 BMW 540i/640i/740i/840i/X5 40i/X6 40i/X7 40i

OVERVIEW

A direct-fit upgrade for your factory air box. The Dinan High Flow Drop-in Replacement Air Filter improves airflow over the restrictive stock paper element, helping the engine breathe more freely for better performance and efficiency — with no cutting or intake replacement required. Built from four layers of oiled cotton gauze, it flows better with less pressure drop than stock media, and because it is washable and reusable it saves money over repeated disposable-filter replacements. Fits the larger G-chassis B58 air box shared across the 40i lineup.
