The Dinan 21-24 BMW 430i Cold Air Intake is a high-performance intake system designed to enhance airflow and engine efficiency. The entire lower box has been reworked and enlarged to maximize available space within the engine bay, allowing for a 40% larger, custom, free-flowing filter to be housed inside. This design ensures maximum airflow and improved throttle response. Additionally, a secondary inlet was developed through extensive testing to effectively fill the enlarged air box without increasing turbo inlet temperatures, maintaining optimal intake air temperatures even during demanding driving conditions.
This intake system is specifically engineered for 2021 to 2024 BMW 430i models equipped with the B48 engine. It is a direct bolt-on upgrade that replaces the factory intake for improved performance and sound. The kit includes the reworked air box, filter, and necessary hardware for installation. Suitable for street and spirited driving, this intake system enhances airflow, power, and throttle response while maintaining engine bay temperatures and reliability.
