Typically, spark plugs for a 2016 Silverado cost about $2-$15 per plug, depending on type, with a full set priced roughly from $12-$120, plus labor.
Engine options and plug counts
The 2016 Silverado offered three main engines, which determine how many plugs you need:
- 4.3L V6: 6 spark plugs
- 5.3L V8: 8 spark plugs
- 6.2L V8: 8 spark plugs
Prices will vary by engine because of the number of plugs and the plug type you choose. Copper-core plugs tend to be cheaper but may wear out faster, while platinum or iridium plugs last longer and cost more up front.
Price ranges by plug type
Before listing typical price ranges, note that exact prices depend on brand, retailer, and regional factors. The following gives a general sense of what to expect per plug and for a full set.
- Copper-core plugs: about $2-$4 per plug. For a 6-plug set (4.3L V6) that’s roughly $12-$24; for an 8-plug set (5.3L or 6.2L) about $16-$32.
- Platinum plugs: about $4-$7 per plug. A 6-plug set runs roughly $24-$42; an 8-plug set about $32-$56.
- Iridium plugs: about $8-$15 per plug. A 6-plug set would be around $48-$90; an 8-plug set around $64-$120.
Prices are approximate and can vary by brand (OEM vs. aftermarket), retailer, and regional taxes or shipping. For GM vehicles, OEM or recommended-equivalent plugs from brands like AC Delco are common choices and may sit within these ranges.
Labor and total replacement costs
Labor costs to replace spark plugs on a 2016 Silverado depend on engine and shop rates, but here’s a typical range you might encounter:
- Labor time: roughly 1.0–2.5 hours for most engines; longer for the 5.3L or 6.2L due to access and coil placement.
- Labor cost: at common shop rates, about $120-$300 depending on location and whether ignition coils or wires are replaced.
Some shops may charge a minimum or diagnostic fee, and replacing wires or coil packs when needed can add to the total. If you’re doing it yourself, you’ll save on labor but still pay for the plugs and any specialty tools.
Summary
For a 2016 Chevy Silverado, plug prices vary by engine and plug type. The 4.3L V6 uses 6 plugs, while the 5.3L and 6.2L V8 use 8 plugs. Copper plugs are cheapest, with platinum and iridium offering longer life at higher cost. Always verify your exact engine and the OEM recommendations, then factor in labor costs if you’re using a shop.
