These specially alloyed heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 170,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware. Come in packs of four with washers included! For use in any 1st gen, 2nd gen, EVO III, or any aftermarket manifold that utilizes the same length bolts as OEM. These bolts also utilize 12-point heads for added "strip" protection over hex head bolts. Highly recommended to apply moly lube to the threads when installing these bolts. Exhaust manifold to turbo torque specs: 40-47 ft. lbs.
