Keep your air-injection emission system routing air where it belongs with the Standard Ignition Secondary Air Injection Pipe (AT183), listed by the manufacturer as a Manifold Air Tube. It installs as a direct-fit replacement for the 1985-1988 Chevrolet G30, 1985-1987 Chevrolet P20, 1985-1988 GMC G3500, 1985-1986 Chevrolet G20, 1985-1986 Chevrolet P30, and 1985-1986 GMC G2500 (see the Buyer's Guide tab for engine-level applications).
A secondary air injection pipe carries air from the air-injection system toward the exhaust to help promote more complete combustion of exhaust gases during operation. Over time these tubes can crack, corrode, or leak at the connections, upsetting the metered air path and potentially triggering emission-related diagnostic codes. If a failed air tube is the cause, this replaces it.
