Standard Ignition Secondary Air Injection Pipe P/N:AT111

Keep your GM V8's secondary air injection system flowing on the right side with the Standard Ignition Secondary Air Injection Pipe AT111. This pipe drops in as a direct-fit replacement for a wide range of early-1980s GM V8 cars and trucks, including the 1981 Buick Century and Regal, 1981-1982 and 1984-1986 Chevrolet Caprice and Monte Carlo, 1981-1982 Chevrolet El Camino, GMC Caballero, and Pontiac Parisienne, plus the 1981-1986 Pontiac Grand Prix — see the Buyer's Guide tab for the full list of covered vehicles and engines.

• Right-side pipe: cataloged for the right-side (RIGHT) position of the engine's air injection plumbing.
• Delivers air to the exhaust: routes pumped fresh air from the air injection system toward the exhaust so oxygen is added to help oxidize unburned hydrocarbons.
• Direct-fit replacement: a straightforward swap for the listed applications, matching V8-4.4L, V8-5.0L, and V8-5.7L engines as shown in the guide.

Over decades of heat cycling, secondary air injection pipes can crack, corrode, or leak at their connections. If a failed or leaking pipe on the right side is the cause of a lit check engine light or a secondary-air system fault, this replaces it — always diagnose the underlying cause before ordering.
