The S63 twin-turbo V8 in the F85 X5M and F86 X6M moves a lot of air. The factory filters do not help it. Each one only pulls from its front and rear faces, for a combined 89 square inches of filter area. That is not much surface for a V8 this size to breathe through.
The Dinan Carbon Fiber Cold Air Intake for the BMW F85 X5M and F86 X6M fixes that bottleneck. Custom filters draw air from their entire perimeter, raising total filter area to 292.4 square inches. That is 228% more than stock. On Dinan's testing it adds up to 23 HP at 5500 RPM and 25 lb-ft at 4000 RPM.
How the Dinan Carbon Fiber Cold Air Intake Makes Room to Breathe
Bigger filters need a bigger box. Dinan enlarged the carbon fiber airbox lid as far as the hood clearance allows, increasing airbox volume by about 15%. The stock lower airbox stays in place, so the fit is factory tight and the install is fast. The lid is genuine carbon fiber, and it changes how the engine bay looks the moment you open the hood. You will hear the difference too, with a more pronounced intake note when you lean on it.
Planning more power later? Dinan reports the intake keeps delivering gains over Stage 1 when paired with its Stage 2 DINANTRONICS Performance Tuner. No tune is required to install it.
Dinan X5M and X6M Intake Install and Legal Status
Install takes about 30 minutes. The Dinan lid and filters work as a set, since the custom filters only fit the Dinan lid. Know this before you order: it is not legal for sale or use in the State of California. Dinan lists it as Emissions Code 7, legal under the EPA Tampering Policy outside California, with CARB testing pending. Dinan part number D760-0047. Sold by AutoTecknic, an authorized Dinan dealer.
