DNN Cold Air Intakes

Dinan has developed the High Flow Carbon Fiber Intake for the BMW E9x M3 to improve airflow to the engine. Dinan's intake is built with the highest quality components and improves the look and performance of your M3 engine with a beautiful carbon fiber connecting pipe and injection molded rubber boots. This intake is sealed tightly from the high temperatures found under the hood by utilizing a Dinan injected molded divider plate with an integral high flow passage that engages into the stock airbox housing. Carbon fiber and plastic were chosen because they are good insulators and have been designed to have a lower mass allowing them to cool off faster than the stock components. This insulating characteristic and rapid cooling after hard acceleration reduce heat in the air intake tract when compared to air intakes constructed of aluminum or other metals. The integrated divider and carbon fiber intake connecting pipe have a 30% more cross-sectional area. This increased area when combined with a high flow filter, ensure maximum airflow for your M3 V8 engine. Dinan High Flow Intake - 2008-2013 BMW M3.
