The GM 12573190 ignition coil is engineered to be a direct OEM replacement for a range of GM LS-series V8 engines, specifically the LS2, LS3, LS4, LS7, and LS9 models. This coil features performance-grade bobbins and brass high-tension terminals for optimal spark delivery and durability. Constructed with premium epoxy, this ignition coil is built to withstand demanding conditions, preventing voltage leaks and RFI interference. Its watertight and weatherproof connectors are made from advanced thermoresistant plastic to resist cracking from heat and thermal cycling. The coil is manufactured in ISO9001:2015 and ISO/TS 16949:2009 certified facilities, ensuring strict quality control for a long service life and perfect fitment. This ignition coil is compatible with numerous GM vehicles from model years ranging generally between 2005 and 2017, including models such as the Chevrolet Corvette, Camaro, Silverado, Tahoe, and GMC Sierra and Yukon. Specific fitment includes 2009 Buick Allure, 2009 Buick Lacrosse, 2006-2007 Buick Rainier, 2006-2007 Cadillac CTS, 2007-2016 Cadillac Escalade, and many more.
