ARP stainless steel intake manifold bolts are 15 percent stronger than Grade 8 steel bolts and have a wide-area flange for better load distribution. They also have precision-rolled threads, which prevent galling and promote more consistent torque loading. These bolts are both corrosion and heat-resistant and come highly polished. Bolts are available in both hex head and 12-point types, and washers are included.
