Original-style smog air injection tube pair for 1969-70 Chevrolet big-block applications.

Designed for the 1969-70 Chevrolet Chevelle and El Camino and 1970 Monte Carlo equipped with big-block V8 engines, these reproduction smog air injection tubes provide an authentic replacement for missing, damaged or deteriorated original components. Each tube is manufactured with accurately formed bends and factory-style inlet and outlet fittings to replicate the original air injection system configuration. The satin black-plated finish provides an original-style appearance, making these tubes an excellent choice for restoring the factory emissions equipment on your classic Chevrolet. The smog air injection tubes distribute air supplied by the engine's air injection system to the exhaust manifolds, helping support the original emissions-control operation. Supplied as a matched pair, these tubes are designed to follow the factory routing and provide proper connections to compatible air injection components. Whether completing an engine compartment restoration or replacing damaged original emissions plumbing, these reproduction tubes help maintain the appearance and functionality of the factory smog system. Additional air injection components and connecting hardware should be verified separately for your application.
