FIREMOTOO Fuel Injector Set of 4 6-Hole for Chevy Cruze 1.4L/1.6L (2016–2019) — OE-Style Fit & Improved Atomization

FIREMOTOO fuel injector set of four (6-hole) is a direct-fit replacement engineered to restore proper spray pattern, fuel atomization, and sealing for compatible GM 1.4L–1.6L engines from 2016–2019.

These four fuel injectors are built from metal and durable polymer components, each featuring a 6-hole spray tip and new O-rings for an improved seal under varied temperatures and pressures. They match OE spray geometry and flow characteristics to help the engine run smoothly and efficiently after replacement. OE cross-reference numbers include 55577403, 12644767, 67901, and FJ1293 — verify fitment with your vehicle year, make, and model before installation.

Will these injectors fit my Chevy Cruze, and how do I confirm compatibility?

Compatibility covers specific GM models and engine sizes listed for 2016–2019. Always check the vehicle’s original injector part number or use fitment tools to ensure the replacement matches your engine variant and wiring harness.

• Fits Chevrolet Cruze 1.4L L4 (2016–2019) and 1.6L L4 (2017–2019)
• Also compatible with Buick Encore 1.4L, Chevrolet Equinox 1.5L, Malibu 1.5L, and GMC Terrain 1.5L (selected years)
• Cross-references OE numbers: 55577403, 12644767, 67901, FJ1293
• Use vehicle year/make/model or OE number to confirm exact fit

How do these injectors affect performance and fuel economy?

These injectors are designed for accurate metering and consistent spray pattern to improve combustion consistency. Correct spray angle and fuel volume, matched to OE specifications, support smoother idling, better throttle response, and more efficient fuel use when properly installed.

• 6-hole nozzle for finer atomization and improved mixture formation
• Spray pattern tailored to factory specifications for consistent combustion
• Can reduce rough idle and hesitation caused by worn injectors
• Helps restore original fuel economy when replacing faulty units

What are the build quality and installation details I should expect?

Each injector combines metal and high-grade plastic components plus fresh O-rings to improve sealing and longevity. They are supplied as a set of four for banks of injectors and are designed for direct installation into compatible engines with no internal modification.

• Constructed with metal/plastic body and new O-rings for improved sealing
• Direct-fit design intended to match OE mounting and electrical connectors
• Sold as a complete set of four injectors for a cylinder bank replacement
• Basic mechanical installation; fuel system depressurization and safety steps required

How should I verify and maintain these injectors after installation?

After installation, check for fuel leaks and proper engine operation before road testing. Periodic inspection and using quality fuel help keep spray patterns consistent and extend service life.

• Inspect O-ring seals and electrical connectors for tight fit and no leaks
• Run an engine warm-up and idle check, listening for smooth operation
• Use recommended fuel and consider periodic injector cleaning if needed
• Confirm no diagnostic trouble codes related to fuel delivery
