Description
The Dinan Cold Air Intake revises the air supply for 1999-2003 BMW 540i, combining application-specific packaging with an intake path intended to reduce restriction.
A cylindrical performance filter is positioned behind the front bumper, below the headlight area, away from the hottest part of the engine compartment. A shaped carbon fiber connecting pipe routes the air toward the airflow meter with fewer unnecessary changes in direction.
