Standard Ignition Secondary Air Injection Pipe P/N:AT139
Keep the secondary air injection system flowing with the Standard Ignition Secondary Air Injection Pipe (Manifold Air Tube), MPN AT115. It installs in the RIGHT-side position as a direct-fit replacement for the 1982-1987 Chevrolet Chevette and 1982-1987 Pontiac T1000 (see the Buyer's Guide tab for engine-level detail). This tube carries air from the air pump toward the exhaust to help oxidize unburned hydrocarbons during warm-up, supporting the emission system's normal operation.
If a corroded, cracked, or leaking air injection pipe is the cause of an air-system fault or failed emissions check, this replaces it. Inspect for rusted, split, or disconnected tubing and confirm fitment for your vehicle before ordering.
