Restore performance and reliability to your GM 3.6L engine with professionally rebuilt 12634126 GDI injectors—flow matched and guaranteed for life.

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 12634126 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 flow matching. 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.

What’s Included:

• ✔ Set of 6 rebuilt GM fuel injectors (Genuine OEM)
• ✔ Compatible with GDI GM 3.6L & 3.0L models (see below)
• ✔ Flow-matched, spray pattern verified, leak tested
• ✔ New o-rings, filters, and seals included
• ✔ Lifetime warranty against defects or failures
• ✔ Ships fast and free from our Florida warehouse
