Dinan Carbon Cold Air Intake – F85 X5M | F86 X6M Dinan

Striking’ is the first word that comes to mind when you pop the hood of an F8X X5M/X6M with a Dinan carbon fiber cold air intake system. The underhood appearance is completely changed and set off by intricate carbon detailing that makes the engine compartment just as flattering as the sleek exterior lines the vehicle possesses. While the aesthetics are the most recognizable change to the system what is more impressive is the functionality that lies beneath the carbon fiber lid.

The care that went into the filter design is what makes the system function as well as it does. The stock filters are restrictive with only a minuscule 89in² in the total filter area. The stock filters also only allow air to be drawn in from the front and rear instead of around the entire surface area. Dinan’s custom filters on the other hand eliminate this wasted area and allow air to be drawn in from all around and increase the total filter area to 292.4in². That’s unheard of a 228% increase in filter area over the stock setup. In order to accomodate these massive filters the stock lid needed to be enlarged as much as the hood clearance would allow. This gave us the opportunity to implement its signature carbon fiber look and appeal while also increasing the overall volume of the airbox by ~15%. The increased volume of the airbox allows the larger filters to ingest more air at any given moment and elicit a slightly more audible and sporty tone over its stock counterpart. This optimized design yields increased HP/TRQ throughout the power band and shows consistent gains over stage 1 when combined with the stage 2 DINANTRONICS Performance Tuner.

Benefits of the Dinan Carbon Fiber High Flow Air Intake for the F85 X5M and F86 X6M:

+ More Power: Max gains of 23 HP @ 5500 RPM and 25 lb-ft of torque @ 4000 RPM  when combined with the Stage 2 DINANTRONICS Performance Tuner and exhaust over stage 1 tuning. 
+ Sportier Sound
+ Improved throttle response
+ ~15% Larger volume airbox via a Carbon Fiber lid that allows for the spacing needed for the larger filters. 
+ 228% increase in filter area (stock: 44.5in² each, Dinan: 146.2in² each)  
+ Dinan filters draw air in from all around versus the stock filters which only draw from the front and back of the filter. 
+ Bolt-on installation

**Due to limited production capacity the F85/F86 X5M/X6M carbon fiber cold air intake is highly susceptible to backorders. New orders placed today would not see shipment for 4 weeks.
