The massive BMW M4 Black Sapphire could only have been taken in for a project by the experts at European Auto Source who can’t say no to a serious challenge when it involves tweaking and tuning BMW’s fine automobiles.

Propelled by a humongous 3.0L Twin Power Turbo engine, you wouldn’t really expect much in the way of tweaking since this engine’s got it all, with the development of around 425HP.

The guys at EAS immediately slammed a new ECU chip on and instantly unlocked the raging BMW M4 Black Sapphire’s full capacity. EAS has devised this “plug ‘n play” solution that after being installed instantly adds 50 – 60HP all in a day’s work. Apart from fixing things under the hood the guys overt at EAS decided to sylize the M4 to match each and every horse it gained through magical tinkering.

For this very reason a new set of H&R springs was fitted on the BMW M4 Black Sapphire followed by a set of spacers which tied the stock rims well within the wheel arches. Black Sapphire painted trimms were added, hence the name which gave the BMW M4 Black Sapphire an overall stealthy fighter jet look.

What is inspiring about the work done on the BMW M4 Black Sapphire by EAS is the fact that the vehicle retains its original look and feel and is only slightly tweaked to get as much juice as it can give.
