Carbon buildup? Misfires? Poor fuel economy? If you drive a GM 3.6L or 3.0L with direct injection, chances are your fuel injectors are failing. These engines rely on precision spray—and dirty tips cause poor atomization, hesitation, and misfires. That's where our rebuilt OEM solution comes in.

You're getting a professionally rebuilt set of 6 Genuine GM 12634126 fuel injectors — not cheap knockoffs or aftermarket substitutions. These Bosch-built OEM GDI injectors are cleaned, rebuilt, ASNU-tested, and flow matched to OEM specs, restoring original performance and drivability.

🔥 Why GDI Injectors Fail (and How We Fix It)

Unlike traditional port injection, GDI injectors sit directly in the combustion chamber. They endure extreme heat, pressure, and carbon buildup — especially around the spray tips.

That exposure leads to:

• Poor atomization and hard starts
• Rough idle and hesitation under throttle
• Check engine lights and fuel trim codes

We combat this with ultrasonic cleaning, ASNU flow testing, and full internal rebuild. Each injector is matched to within 2% tolerance and only ships if it passes all OEM-spec testing. If it doesn’t pass, it doesn’t ship.
