Spark plugs for a 2014 Chevy Traverse typically cost between $2 and $15 per plug, depending on the type. For six plugs, parts alone usually run about $12 to $90. With installation, total prices at a shop generally range from roughly $150 to $350, though dealer quotes can be higher and DIY savings are possible if you provide your own parts.
The following guide reflects current market pricing as of 2026 and explains how plug type, OEM vs aftermarket options, and labor influence overall cost. The Traverse uses a coil-on-plug ignition system, meaning replacing all six plugs involves accessing each coil and plug together.
Price ranges by plug type
Copper spark plugs
Typical price: about $2 to $5 per plug; six plugs would cost roughly $12 to $30 for parts.
Platinum spark plugs
Typical price: about $4 to $9 per plug; six plugs would cost roughly $24 to $54 for parts.
Iridium spark plugs
Typical price: about $8 to $15 per plug; six plugs would cost roughly $48 to $90 for parts.
Note: OEM or brand-name options can fall into these ranges, and some retailers offer multi-pack discounts that reduce the per-plug price. Prices can vary by retailer, region, and whether the plugs are standard or long-life designs.
Labor and installation considerations
How labor costs vary
Labor to replace six spark plugs on a 2014 Traverse generally falls into these ranges, depending on the shop and location:
Independent auto repair shop: approximately $100 to $200
Dealership or GM-certified shop: approximately $200 to $350
DIY (parts only): pay only for plugs (see price ranges above) and save on labor, provided you have or rent the necessary tools and can complete the job safely.
These figures assume no additional issues such as faulty ignition coils or seized plugs. If a coil-on-plug system requires coil replacement or you encounter stubborn plugs, both parts and labor can increase.
Shopping tips and buying advice
To ensure you select the correct plugs for your 2014 Traverse, confirm the exact engine code and consult the owner’s manual or a trusted parts catalog. Popular brands include ACDelco (OEM), Denso, NGK, Bosch, and Champion. Compare prices across major retailers such as AutoZone, Advance Auto Parts, O'Reilly Auto Parts, and RockAuto. When choosing plugs, consider your maintenance interval goals and whether iridium or platinum plugs better balance longevity with upfront cost.
Summary: For a 2014 Chevy Traverse, spark plug costs vary by type, typically totaling $12–$90 for six plugs in parts. Including labor, total replacement costs commonly range from about $150 to $350 in the U.S., with variations by location and shop. Doing it yourself can cut labor costs, while dealer service may be pricier but convenient and warranty-friendly.
