The owner of this triple black 335i wanted to extract additional power from his N54, but also wanted to maintain its stealthy appearance. To do this, we first installed the popular Burger Motorsport JB4 tuner in conjunction with a set of thermal coated Macht Schnell catless downpipes; together, they add substantial horsepower and decrease turbo lag. Concerned about heat build-up, we then installed the larger Evolution Racewerks intercooler and the twin oil cooler upgrade, both of which were black anodized for additional cooling and a hidden appearance. Having already been fitted with a set of Performance Friction brakes, this Black Sapphire E90 is more than ready to handle its new power. Enjoy.
