The Dinan High Flow Intake for the BMW E9X M3 replaces the factory air delivery path with a carbon fiber connecting pipe and injection-molded rubber boots, adding 30% more cross-sectional area to the intake tract compared to the OEM equivalent. The system seals against underhood heat using a Dinan-designed injection-molded divider plate that integrates directly with the factory airbox housing, maintaining thermal isolation without requiring a new airbox. Carbon fiber and injection-molded materials were selected for their insulating properties and low thermal mass: they cool faster after hard acceleration than aluminum or steel alternatives, keeping charge air temperatures lower during sustained spirited driving.
