The 2014 Chevrolet Cruze uses iridium-tipped spark plugs, with the exact part number depending on the engine (1.8L naturally aspirated or 1.4L turbo). Always verify the precise specification from GM’s parts catalog or the owner’s manual for your vehicle.
In the 2014 Cruze lineup sold in North America, two four-cylinder engines were common: a naturally aspirated 1.8-liter and a 1.4-liter turbo. Both use high-quality plugs designed for longevity, and replacement should use OEM-grade plugs (GM/ACDelco) or suitable equivalents from trusted brands such as NGK or Denso. To ensure you get the right plug, check the official documentation or consult a dealer with your VIN.
Engine options for the 2014 Cruze
Two engine options were commonly available in 2014 Cruze models, and each uses a high-quality spark plug chosen for its design and longevity:
1.8L Naturally Aspirated I4
This engine generally uses iridium or platinum spark plugs designed for longer service life. When replacing, you should use OEM-grade plugs from GM/ACDelco or trusted aftermarket equivalents that match the specified heat range and thread size for the 1.8L engine.
1.4L Turbocharged I4
The 1.4L turbo also uses iridium or similar high-quality plugs. Replacement should follow GM guidance or equivalent aftermarket options that meet the engine’s heat range, gap, and thread specifications. Always confirm the exact part number for your engine code.
How to confirm the exact spark plug part number for your vehicle
To ensure you purchase the correct plug for your 2014 Cruze, use these steps:
- Check the vehicle’s owner’s manual or service manual for the recommended spark plug specification.
- Look for a sticker under the hood or on the radiator support that lists spark plug type and gap for your engine.
- Use your VIN to search the GM Parts Catalog or an authorized parts retailer to pull the exact GM-approved part number.
- If in doubt, contact a Chevrolet dealer or a reputable shop with your VIN and engine code to confirm the correct plug and gap.
Having the exact part number ensures compatibility with your engine’s ignition system and helps maintain performance and efficiency. If you’re switching brands (for example, from OEM to a high-performance aftermarket plug), confirm heat range and gap specifications with the supplier or a qualified technician.
Summary
The 2014 Chevy Cruze generally uses iridium-tipped spark plugs, with the exact number depending on whether you have the 1.8L or the 1.4L turbo engine. Always verify the correct plug via the owner’s manual, GM Parts Catalog, or a dealership using your VIN, and stick to OEM-grade plugs or trusted equivalents that match the engine’s specifications. Proper replacement helps maintain fuel efficiency, performance, and reliability.
