The Dinan carbon fiber intake looks as good as it performs, allowing more outside air to be pushed into the engine via twin-ducts while also providing structural stiffness to the strut towers. Two new air inlets are added, each with its own high flow filter mounted into the mouth of the carbon fiber inlet. The stock air inlet is fully functional to provide four intakes into the engine for maximum airflow. The filtered air passes from the inlets into the black powder coated ducts then directly into the engine.
The Dinan Engineering team had a special challenge with the F10 550i. With very little room to work with under the hood the team came up with the ingenious idea of combining the shock tower brace and the inlet tube into one part. The results are beautiful and purposeful looking.
Benefits of the Dinan Carbon Fiber High Flow Air Intake – Strut Tower Brace for the F10 550i:
+ More Power +10 HP & +8 lb-ft of Torque (with Software Upgrade)
+ Beautiful Dual Carbon Fiber Inlets
+ Integrated Strut Tower Brace
+ Stock System Stays Completely Functional
Performance Engine Software (D900-44T5, D903-44T52, D903-44T53, D903-44T54, D903-44T55): The Dinan Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. In fact, over 2000 lines of code have been addressed, producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. There are 5 different stages of software that can be utilized for additional power gains when used in conjunction with additional Dinan performance products.
Free Flow Stainless Exhaust (D660-0036 & D660-0036-BLK): An important addition for any enthusiast who wishes their car to sound as good as it performs while also supplying significant power gains itself. These exhausts are dyno tested for maximum exhaust flow with minimum backpressure. The system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to Dinan’s exclusive Butterfly Valve technology.
