RAWOK Ignition Coil UF669 with 4 Double-Iridium Spark Plugs 1675 for 1.4L Turbo Chevy/Buick — OEM Fit, Improved Ignition

RAWOK Ignition Coil UF669 with four double-iridium spark plugs 1675 is a drop-in replacement kit engineered for 1.4L turbocharged Chevrolet and Buick engines to restore reliable sparks and consistent firing.

If your 1.4L turbo Chevy Cruze, Sonic, Trax or Buick Encore has rough idling, misfires, or reduced throttle response, worn ignition parts are a common cause. This RAWOK kit includes one UF669 ignition coil and four double-iridium 1675 spark plugs sized for 1364cc turbocharged 1.4L engines. Parts are manufactured to OEM-equivalent specifications so they fit the listed model years and bolt in without modification.

Which vehicles and engines are these parts compatible with?

This kit is intended for turbocharged 1.4L (1364 cc) engines used in specific Chevrolet and Buick models. It covers model-year ranges where the OEM part numbers UF669/1675 or equivalents are used.

• Chevrolet Cruze Limited 2011–2015 (1.4L turbo)
• Chevrolet Sonic / Trax 2012–2020 (selected years listed by manufacturer)
• Buick Encore 2013–2021 (1.4L turbo)
• Ensure your engine code and OEM part number match before purchasing

How does the ignition coil and double-iridium plug combination help engine performance?

The coil supplies high-voltage current to the spark plugs while the double-iridium electrodes provide a stable, concentrated spark. Together they improve ignition consistency across operating conditions, which helps smoother idling and more reliable start-up when installed correctly.

• UF669 coil built to OEM tolerances for direct replacement
• Double-iridium plugs offer a focused spark and extended electrode life
• Kit supports up to typical service intervals (manufacturer guidance applies)
• Replacing coil and plugs together avoids mismatched wear and performance loss

What should I check before I buy and how easy is installation?

Confirm vehicle year, engine size (1.4L turbo), and OEM part numbers using your vehicle information or an online compatibility checker. Installation is a standard ignition swap: remove the old coil and plugs, fit the new coil and torque plugs to specification, and reconnect wiring. If you are unsure, a professional technician or a service manual is recommended.

• Use the Amazon confirmed fit or VIN lookup to verify compatibility
• Follow torque specs and anti-seize guidance for spark plugs
• Check wiring harness condition before reusing connectors
• Basic hand tools and 30–60 minutes typical for an experienced DIYer

How long can I expect these parts to last and what are maintenance tips?

Double-iridium plugs generally outlast standard plugs due to harder electrodes and stable spark geometry; typical life varies by driving style and conditions. The ignition coil life depends on heat cycles and electrical load—replacing coils with deteriorated plugs reduces stress and extends both components' service life.

• Inspect coils and boots for cracks or oil contamination during service
• Replace plugs at recommended intervals or when symptoms appear (misfire, rough idle)
• Keep ignition connectors clean and dry to prevent voltage leaks
• Using all new plugs and coil together helps maintain balanced firing

Who is this for: This RAWOK kit is aimed at owners and technicians working on Chevrolet and Buick small-turbo 1.4L engines who need a direct-fit ignition coil and high-durability spark plugs. It suits DIY mechanics wanting an OEM-equivalent replacement and professional shops seeking a reliable, ready-to-install kit for vehicles listed in the compatibility section. Always verify fit with your vehicle’s VIN or OEM part numbers before ordering to avoid mismatches.
