Description

The GM Genuine Parts exhaust manifold gasket (MPN 12617944) is a direct replacement part engineered by General Motors to maintain the integrity of your vehicle's exhaust system. It is constructed from durable stainless steel, with specific dimensions including a mounting hole diameter of 9.18 mm and a thickness of 0.75 mm. This genuine GM part is designed, engineered, and tested to meet the same rigorous standards as the original components installed in Chevrolet, Buick, GMC, and Cadillac vehicles. GM regularly updates its part designs with new materials and technologies to enhance performance and reliability. This specific gasket replaces GM part numbers 12558573 and 12600530. It is crucial to verify fitment for your specific vehicle. The GM 12617944 exhaust manifold gasket is compatible with a wide range of GM vehicles, including various models of Buick Allure, LaCrosse, and Rainier; Cadillac CTS and Escalade; Chevrolet Avalanche, Camaro, Colorado, Corvette, and Express; and GMC Savana, Sierra, and Yukon. Detailed fitment information, including specific years, engines, and body styles, is available to ensure correct application. The part is backed by a 2-year factory warranty.
