Replacement Coolant Lines for GrimmSpeed Turbos

In need of replacement coolant lines for your GrimmSpeed JB400 or BB500 Turbocharger? We've got you covered. These lines are made from stainless steel and zinc coated for extreme durability and corrosion resistance. Our turbos utilize a cross-flow cooling layout rather than the factory design with the inlet and outlet on the same side of the center housing rotating assembly (CHRA). Despite this, The Grimmspeed Coolant Lines have been designed to line up with the factory feed and return soft lines, so installation is a breeze!
