We now offer our new Deep Brass Freeze Plug kit. Includes extra depth brass block plugs, oil galley pipe plugs and cam plug. These plugs are a deep cup design, to provide more sealing surface against the block. This helps to provide a stronger, leak proof seal. And, the brass material has much better resistance to corrosion, making it a nice upgrade from the standard steel material that the factory used. Can be left as unpainted brass finish, or painted engine color after installation.
