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.
Dinantronics Performance Tuner (D440-1603-ST1 & D440-1603-ST2): The DinantronicsT Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device emissions legal in all 50 states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package.
