BRAND
RK Autowerks
RK Autowerks machines billet intake manifolds, port injection hardware, and turbo kits in-house for BMW S58, S55, B58 and S63 platforms. We stock their induction and fueling parts for builds that have outgrown what a plastic manifold and a factory fuel system will tolerate.
WHY WE SHIP RK AUTOWERKS
RK Autowerks builds the induction and port-injection hardware we reach for when a build is being made to live at power rather than survive a single dyno pull. The factory intake manifold on these engines is plastic, and sustained boost eventually finds that out. A billet manifold with the fuel rail machined into it removes that failure point and gives a tuner a second fuel path to work with, which is what actually unlocks full ethanol and a safe air/fuel ratio at load. Their parts are designed, machined and assembled in-house in Texas, and the tolerances hold up when we put them on a car. We ship RK where the fuel system, not the turbo, is what is standing between the customer and the number.
