'Striking' is the first word that comes to mind when you pop the hood of a?F8x X5M/X6M with a Dinan carbon fiber cold air intake system. The under hood appearance is completely changed and set off by intricate carbon detailing that?make 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 miniscule 89in? in 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 292.4in?. That's an unheard of 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?it's signature carbon fiber look and appeal while also increasing the overall volume of the airbox by ~15%.?The?increased volume of the air box 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 air box via a Carbon Fiber lid?that allows for the spacing needed for the larger filters.?
+?228% increase in filter area (stock:?44.5in??each,?Dinan:?146.2in? 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
