Pjvmvo Fuel Injectors for 2010–2014 GM 4.8L/5.3L/6.0L FLEX — Set of 8, OE Fitment Restored Performance

Pjvmvo's set of eight 12613411 FLEX fuel injectors replaces worn units in 2010–2014 GM 4.8L, 5.3L and 6.0L engines for restored fuel delivery and reliable operation.

If your Tahoe, Silverado, Suburban, Avalanche, Yukon, or Sierra with a FLEX fuel system is showing signs of rough idle, reduced efficiency, or uneven throttle response, worn injectors are often the culprit. These Pjvmvo injectors arrive new, inspected, and matched to confirmed OE fitment so they drop into the factory fuel rail and connector without modification. The kit is sold as a complete set of eight injectors and is intended for GM 1500-series vehicles from 2010 through 2014 that use the 4.8L, 5.3L or 6.0L FLEX fuel setups.

How do these injectors match my vehicle’s fitment?

Each injector in the set is selected to meet the manufacturer’s dimensions and electrical connector style, ensuring plug-and-play compatibility. Pjvmvo cross-references OE part numbers and conducts a confirmed-fit matching process so the hardware aligns with factory mounts and fuel lines.

• Replaces OE number 12613411 / Replace# 2173411 reference
• Compatible with 2010–2014 GM 1500-series FLEX fuel 4.8L, 5.3L, 6.0L engines
• Standard electrical connector and mounting O-rings included
• Sold as a set of eight for complete bank replacement

What performance and quality checks are done before shipping?

Pjvmvo inspects, disassembles, cleans, and tests every injector prior to stocking to ensure they meet quality standards. Parts that pass are repackaged and undergo multiple pre-delivery checks so you receive functional components ready for installation.

• Individual flow and spray-pattern testing performed
• Cleaning to remove manufacturing residues and contaminants
• Leak checks and electrical continuity tests
• Final inspection recorded before shipment

Will installation require special tools or modifications?

These injectors are designed for direct replacement and typically install with basic hand tools and common shop supplies. You should replace injector O-rings and seals during installation and follow standard fuel-system safety precautions to avoid spills and fumes.

• Standard O-ring removal and installation tools recommended
• Fuel rail removal may be needed depending on vehicle model
• Torque specifications: use factory-specified values for rail bolts
• Expect minor residual fuel in tested injectors — normal and safe when handled correctly

How will replacing all eight injectors affect drivability?

Replacing the full set restores consistent fuel delivery across all cylinders, improving idle smoothness, throttle response, and engine balance. A matched set prevents cylinder-to-cylinder variations that can cause misfires or reduced efficiency, especially on higher-mileage FLEX-fuel vehicles.

• Smoother idle and reduced rough-running episodes
• More consistent acceleration and throttle response
• Helps stabilize combustion across cylinders
• Supports fuel-system diagnostics by eliminating injector variance

Who is this for: This complete set of eight Pjvmvo 12613411 FLEX fuel injectors is aimed at owners and mechanics of 2010–2014 GM 1500-series trucks and SUVs (Tahoe, Silverado, Suburban, Avalanche, Yukon, Sierra) running 4.8L, 5.3L or 6.0L FLEX fuel engines who need a reliable, OE-matching replacement. It’s a suitable choice when multiple cylinders show injector-related symptoms or when performing a thorough fuel-system refresh during maintenance or repair.
