High Flow Carbon Fiber Cold Air Intake (D760-0035):  Dinan high flow carbon fiber cold air intakes, like most Dinan products, have a sleek and functional appearance that embodies high performance. The F10 M5 cold air intake allows cool outside air to be pushed into the engine via a pair of supplemental carbon fiber intake ducts located at the front of the engine bay. Dinan engineers have painstakingly developed custom tooling to ensure the entire Dinan cold air intake system is sealed like a factory replacement, thereby preventing hot air from the engine compartment to compromise its effectiveness.  Improved induction airflow offered by Dinan cold air intake systems increase engine performance, even more so if used in combination with other performance enhancing Dinan products.
