In the 2017 Altima, the total cost to replace spark plugs depends on the engine type and the plug selection. For the 2.5L four-cylinder, you’ll typically pay about $150–$350, while the 3.5L V6 variant can range from roughly $300–$600, including parts and labor in most U.S. markets.
Spark plug replacement is a common maintenance job. The Altima uses a coil-on-plug setup, so service usually involves removing ignition coils and installing new plugs. Prices vary widely by region, shop, and whether you use standard copper plugs or longer-life iridium/platinum options. If coils or related parts show wear, the bill can rise accordingly.
Engine variants and cost breakdown
Prices and labor times differ between the 2.5L four-cylinder and the 3.5L V6. The estimates below reflect typical ranges from a standard U.S. shop.
- 2.5L four-cylinder: Parts for four plugs typically range from about $20 to $80, depending on plug type; labor is about 0.8 to 1.5 hours at a typical rate of $75 to $150 per hour. Total commonly falls in the $100 to $260 range, with higher-cost markets sometimes reaching $300.
- 3.5L V6: Parts for six plugs typically range from about $40 to $120; labor about 1.5 to 2.5 hours at $75 to $150 per hour. Total commonly falls in the $200 to $450 range, with some high-cost markets pushing toward $500–$600.
These figures are intended as ballpark guidance. Exact quotes depend on regional labor rates, the specific plug brand and type chosen, and whether any additional maintenance items are bundled into the service.
What affects price and ways to save
Several factors can push the bill up or down. The list below outlines typical price drivers and practical ways to save.
- Plug type and brand: Copper plugs are cheaper than platinum or iridium plugs; longer-life options may cost more upfront but save on replacement frequency.
- Engine variant and labor: A V6 with six plugs takes longer to service than a four-cylinder; labor rates vary by region and shop.
- Charging for extra services: Some shops include coil inspection, coil replacement, or a basic tune-up in the same job, which can affect the total.
- Regional price differences: Urban areas and shops with a higher cost of living generally charge more for labor.
To keep costs predictable, request a written estimate that itemizes parts and labor and confirm whether a stock or premium plug is required by your vehicle’s warranty or Nissan guidance.
DIY considerations
Replacing spark plugs yourself can save on labor in some markets, but it requires the right tools and careful adherence to torque specifications. The 2017 Altima’s four-cylinder variant is typically approachable for a DIYer with basic mechanical skills; the V6 version is more involved. Consult the service manual or a trusted tutorial before attempting it yourself.
Summary
For most 2017 Altima owners with the 2.5L engine, expect roughly $150–$350 to replace spark plugs when including parts and labor. If your Altima uses the 3.5L V6, budget about $300–$600. Prices vary by plug type, region, and shop, so always compare quotes and consider long-term maintenance benefits when choosing plugs.
