RAWOK Ignition Coil and 4 Double Iridium Spark Plugs Kit for 1.4L Turbo Chevy/Buick (UF669, 1675) – OEM Fit, Longer Life

RAWOK’s kit includes one UF669 ignition coil and four double iridium spark plugs (1675) designed to restore reliable ignition and steady engine performance for 1.4L turbo Chevy and Buick models.

This plug-and-play replacement set is engineered to meet OEM specifications and fits 1.4L (1364 cc) turbocharged engines found in select Chevrolet and Buick vehicles from 2011–2021. The coil and iridium plugs are matched to improve spark consistency, reduce misfires, and deliver longer service life than standard plugs. Before installation, verify vehicle compatibility using your VIN or the confirmed-fit tool to avoid ordering the wrong part.

What vehicles and engines is this RAWOK kit compatible with?

The kit is intended for turbocharged 1.4L engines (1364 cc) in specific Chevrolet and Buick models. It covers many model years for the Cruze, Sonic, Trax, and Encore listed below, but confirm exact fitment for your VIN.

• Chevrolet Cruze: select 2011–2016 and Cruze Limited 2016–2015 1.4L Turbo variants
• Chevrolet Sonic: many 2012–2020 1.4L Turbo trims
• Chevrolet Trax: select 2015–2021 1.4L Turbo models
• Buick Encore: 2013–2021 1.4L Turbo models

How do the UF669 coil and double iridium plugs improve ignition performance?

The UF669 coil supplies a consistent, high-voltage pulse while the double iridium plugs provide a small, durable electrode for focused spark energy. Together they create a stronger, more reliable combustion event compared with worn coils or conventional plugs.

• Higher voltage output from the coil for steadier firing
• Double iridium tips for longer life and consistent spark gap
• Reduced misfires and smoother idle under typical driving loads

Are these parts easy to install and do they meet OEM standards?

Yes—RAWOK builds the coil and plugs to OEM-aligned dimensions and electrical characteristics, so installation follows the same steps as the original components. Basic hand tools and basic mechanical knowledge are usually sufficient; torque the plugs to the manufacturer’s spec and ensure electrical connectors are secure.

• OEM-style fit and electrical compatibility for direct replacement
• Simple swap procedure: remove old coil and plugs, fit new parts, reconnect
• Follow torque spec and gap recommendations in the vehicle manual

How long can I expect these parts to last and what maintenance should I do?

RAWOK’s double iridium plugs are rated for extended service life—commonly up to tens of thousands of miles under normal driving—and the coil is tested for reliable operation. Lifespan varies with driving conditions, fuel quality, and maintenance habits.

• Double iridium plugs designed for longer intervals than plain copper or standard nickel plugs
• Coil tested to OEM-like standards for consistent output over time
• Inspect ignition system when performing routine tune-ups and replace as needed

Who this is for: Drivers and DIY technicians who own a compatible Chevy Cruze, Sonic, Trax or Buick Encore with the 1.4L turbo engine and want a cost-effective, OEM-style ignition refresh. This RAWOK kit suits owners repairing misfires, restoring throttle response, or replacing worn plugs and coils during scheduled maintenance. Always verify fitment using your vehicle details before purchase to ensure proper compatibility.
