BD Diesel has something new for you! Their ISX manifold allows you to replace your Holstet HE 551 air or HE 561 electronic turbo with the new Borg Warner S410SX. The manifold can withstand extreme ranges, and works together with the Borg Warner to deliver better pulling power, lower operating cost, and more hours of use with less break downs. BD manifolds are built out of thick high-silicon cast iron and feature two equally placed slip joints that allow for heat expansion. In addition, the pulse design of the manifold enhances turbine response. For more information, call 1-800-887-5030 or visit www.dieselperformance.com.
