This is a complete set of 8 brand new, OEM GM fuel injectors, part number 12613412. They're made by Delphi for GM and are a direct replacement for various 2010 to 2013 Chevy, Cadillac, and GMC models (you'll need to check specific fitment for your vehicle). The set comes with a 1-year manufacturer warranty. It's a custom bundle, meaning you get all eight injectors together, which is smart because replacing them as a set ensures even fuel delivery and performance. Cross-reference part numbers include 217-3412, M1410, FJ1089, 67696, and FJ10736. If your truck or SUV is misfiring, has poor fuel economy, or shows injector-related codes, this set can sort it out. New in original packaging, these are the real deal OEM parts, not cheap knock-offs. Good for DIY mechanics or shops.
