Description
The Dinan Cold Air Intake revises the air supply for 2019-2026 BMW Z4 M40i, combining application-specific packaging with an intake path intended to reduce restriction.
The revised housing and filter arrangement increase the available breathing area. A semi-open inlet exposes more induction sound while retaining the application-specific airbox layout, providing a different sound character from a fully sealed system.
