How much does it cost to replace spark plugs in a Toyota Tundra?
Replacing spark plugs in a Toyota Tundra typically costs between roughly $200 and $900, depending on the engine option, spark plug type, and labor rates. The final price can vary with your specific model—2.7L I-4, 3.5L V6, 5.7L V8, or hybrid variants—as well as whether you use OEM plugs or aftermarket equivalents and whether any related components (like ignition coils or wires) need service.
To understand the question in depth, it’s important to consider the engine configuration, spark plug technology, and regional labor costs. Different Tundra engines require a different number of plugs and may present varying levels of accessibility, which drives both parts costs and the time technicians spend on the job. Below is a breakdown of typical price ranges you’re likely to encounter at shops or dealerships.
What affects the price
The cost of replacing spark plugs on a Toyota Tundra is influenced by several factors that can shift the final bill up or down. A few of the most impactful elements are listed here to provide context before looking at engine-specific estimates.
- Engine type and number of spark plugs: The 2.7L I-4 uses four spark plugs, the 3.5L V6 uses six, and the 5.7L V8 uses eight. Hybrid variants add complexity that can affect labor time.
- Spark plug type: Iridium or platinum plugs typically cost more per plug than cheaper copper or standard platinum options; many newer Tundras use iridium or iridium-tipped plugs with longer service intervals.
- Labor rates and shop location: Urban areas or dealer service centers often charge higher hourly rates than independent shops.
- Accessibility and related work: If ignition coils, boots, or wires need replacement, the job time and parts cost can rise.
- DIY vs. professional service: Doing it yourself saves labor but requires the right tools and know-how; DIY the plug price plus any tool purchases is the main difference.
With these factors in mind, here are typical price ranges you’re likely to see for common Tundra configurations.
Estimated cost by Tundra configuration
Prices below reflect typical ranges for parts and labor as of 2025 and may vary by region, dealer, or independent shop. They assume standard spark plugs (often iridium/platinum) and do not include taxes or disposal fees.
- 2.7L I-4 turbo (4 spark plugs): Parts roughly $20–$60; labor about 1.5–2.5 hours at roughly $100–$150/hour; total estimated range $190–$410.
- 3.5L V6 (6 spark plugs): Parts roughly $60–$120; labor about 1.5–3 hours at roughly $100–$150/hour; total estimated range $240–$600.
- 5.7L V8 (8 spark plugs): Parts roughly $80–$160; labor about 2–4 hours at roughly $100–$150/hour; total estimated range $280–$760.
- Hybrid i-FORCE MAX variants (6 spark plugs, added complexity): Parts roughly $60–$120; labor about 2.5–5 hours at roughly $100–$150/hour; total estimated range $310–$840.
Note: Some shops may quote a flat diagnostic or shop supply fee, and taxes or environmental fees may apply. If a workshop replaces additional components (coils, wires, gaskets), the total will be higher than these estimates.
DIY considerations and tips
For readers comfortable with car maintenance, replacing spark plugs yourself can reduce labor costs substantially. Expect to pay only for parts and any tools you may need. Ensure you have the correct replacement plugs specified for your engine, follow Toyota’s torque specs, and consider replacing ignition coils or boots if they show signs of wear during the job.
Always verify current part numbers and recommended service intervals in your owner’s manual or with a trusted parts dealer, as specifications can change with model year and trim level.
Summary
Across the Toyota Tundra lineup, spark plug replacement costs vary mainly by engine type and labor rates. A practical range spans roughly $200 to $900, with common configurations clustering in the $240–$760 zone depending on the engine and whether additional parts are required. For a precise quote, contact a local dealer or reputable shop with your exact model year and engine choice in hand.
