GM 12634126 GDI Fuel Injectors - Genuine Rebuilt OEM - 2012-2024 3.6L 3.0L

Carbon buildup? Misfires? Poor fuel economy? If you drive a modern GM 3.6L 3.0L vehicle with direct injection, those symptoms point straight to your fuel injectors, robbing you of your performance and fuel economy.

You're getting a professionally rebuilt set of 6 Genuine GM 12634126 fuel injectors — not offshore knockoffs or generic replacements. These OEM GDI injectors are fully cleaned, ASNU tested, and flow-matched to deliver like-new performance and restore your engine’s original precision.

Why GDI Injectors Fail:
Unlike multiport fuel systems, GDI injectors sit inside the combustion chamber. That means direct exposure to heat, pressure, and carbon buildup — especially at the spray tips. Over time, this leads to poor atomization, hard starts, rough idle, hesitation, and eventually cylinder misfires.

We address all of that by ultrasonically cleaning each injector, flow testing on ASNU equipment, and confirming spray pattern and delivery rates are OEM-spec. If it doesn't pass, it doesn't ship.
