The Dinan intake for the 1999-2003 E39 540i relocates the intake filter to an area of low pressure behind the front bumper. The filter is no longer sucking hot air from the engine compartment. Instead it draws in cooler, denser, more oxygen-rich air into the intake.
Note: For model build date of 10/1998 and up.
