2007 BMW Z4 M Roadster 'Supercharged'

While this E85 Z4 M Roadster may look stock from the outside, it is producing 525hp thanks to an aftermarket supercharger. All of the proper supporting hardware has been fitted including a less restrictive intake manifold, bigger injectors, and a high capacity intercooler. A SuperSprint exhaust reduces pumping losses while offering more music out the back, and a custom ECU tune unlocks additional power.
