Secondary Air Injection Hoses, Clamps, and Pipes

AIR hoses are made of heat resistant, non-reinforced rubber. Clamps, designed for high temperature conditions, connect the hoses to the pump and check valve/pipe assemblies of each cylinder bank. The air injection pipes, connected to the exhaust manifolds, are high temperature, corrosion resistant stainless steel.
