GELUOXI Ignition Coil Replacement for 1.4L ECOTEC (Cruze Sonic Trax Volt Encore ELR) — Direct Fit, OE Cross-Reference

GELUOXI Ignition Coil Replacement is a direct-fit ignition coil engineered to restore spark performance on 1.4L GM ECOTEC engines used in Cruze, Sonic, Trax, Volt, Encore and ELR models from 2011–2021.

This replacement coil is built to match original equipment fitment and electrical characteristics for the 1.4L L4 turbo ECOTEC family. It lists multiple OEM cross-reference numbers, fits a wide range of Chevrolet, Buick and Cadillac models, and is intended as a like-for-like swap for failed or worn ignition coils. Before ordering, compare the plug-and-play connector, mounting points and OE numbers to your existing coil to ensure compatibility.

How do I know this coil fits my vehicle?

Compatibility is based on engine family and OEM part cross-references. GELUOXI provides common OE numbers that match many factory coils for 1.4L GM engines; verify your vehicle year, engine code and the part number stamped on your original coil.

• Supported OEM numbers include 55577898, 55579072, 25198623 and others listed.
• Compatible with 2011–2015 Chevrolet Cruze and 2016 Cruze Limited 1.4L L4.
• Also fits 2012–2020 Sonic, 2013–2021 Trax, 2011–2015 Volt, 2013–2021 Buick Encore, 2014–2016 Cadillac ELR.
• Always compare photos and OE numbers before purchase for an exact match.

What improvements or features does this replacement offer?

The GELUOXI coil is designed to replicate the original coil’s electrical output and mechanical fit. It aims to deliver consistent spark energy and reliable connection to the factory harness while being straightforward to install.

• Direct-fit dimensions and mounting to replace factory coils without modification.
• Factory-style electrical connector to plug into the existing wiring harness.
• Durable housing and insulation to resist heat and engine-bay contaminants.
• OE cross-reference coverage to simplify part selection for multiple GM models.

How difficult is installation and what tools are needed?

Installation is typically simple for anyone comfortable working in an engine bay. The job normally requires removing the engine cover (if equipped), unplugging the electrical connector, unbolting the coil, and swapping in the new unit.

• Basic hand tools: ratchet, appropriate sockets and a small extension.
• No special programming or dealer setup required for most applications.
• Torque the mounting bolt to factory specification and ensure connector seats fully.
• Check for error codes after installation and clear codes if necessary.

Will replacing one coil fix rough idle or misfire codes?

Replacing a faulty ignition coil is often the correct step when a cylinder misfire or rough idle is traced to that coil. However, a misfire can result from multiple causes, so diagnosis before replacement improves the chance of fixing the issue.

• Replace coils tied to a confirmed misfire code (P0301–P0304, etc.).
• Inspect spark plugs and wiring—coils and plugs are commonly replaced together.
• If codes persist, further testing of fuel, compression and sensors may be needed.
• Use OEM cross-reference numbers to ensure you bought the correct coil.

Who is this for: This GELUOXI ignition coil is for DIY mechanics, independent shops and fleet technicians seeking a dependable, direct-fit replacement for 1.4L GM ECOTEC engines in Cruze, Sonic, Trax, Volt, Encore and ELR models. Choose this part if your vehicle exhibits cylinder-specific misfires, ignition coil fault codes, or degraded engine performance and you need a coil that matches OE specifications and connector geometry.
