Description
The Dinan PEX Cold Air Intake revises the air supply for 2021-2024 BMW 430i, 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.
Secondary openings are positioned away from the engine to supplement the original air feed. Their purpose is to make use of the larger filter and housing while balancing airflow with exposure to engine-bay heat.
