How much does it cost to replace spark plugs in a 2013 Lexus GS 350?
Replacing all six spark plugs on a 2013 Lexus GS 350 typically costs about $300 to $600, depending on parts choice and labor rates. Dealer quotes can be higher, while independent shops generally fall on the lower end.
What goes into the price
Costs are driven by parts, labor, and shop-specific factors. Here’s how each component tends to affect the total:
- Parts: six spark plugs (iridium long-life type are common for the 2GR-FSE engine) and, if needed, ignition coils or related hardware.
- Labor: time to access the plugs, remove and reinstall coils, torque specifications, and any incidental tasks.
- Diagnostics and shop fees: initial inspection, diagnostics, disposal, and shop supplies.
- Region and shop tier: dealership vs. independent shop, urban vs. rural pricing, and local labor rates.
In most GS 350 jobs, the spark plugs themselves are the primary cost driver; coils are only replaced if they fail or show symptoms.
Typical cost ranges
Use these ranges as a general guide based on common pricing in the United States. Exact numbers will vary by location and shop.
- Parts: Iridium spark plugs for the 2GR-FSE engine typically cost about $10–$25 each, totaling roughly $60–$150 for six plugs.
- Labor: Labor time is usually 1.5–2.5 hours at shop rates of roughly $80–$150 per hour at independent shops, or $150–$210 per hour at a dealership; expect about $120–$375 in labor.
- Estimated total: Roughly $180–$525 in many markets, with dealer quotes potentially higher and some specialty shops charging more if additional work is required.
Note that coil packs or ignition coil replacements are not typical unless a fault is found during inspection, which can push the total higher.
DIY vs professional service
Deciding whether to tackle the job yourself or have a professional handle it depends on tools, experience, and warranty considerations. Access on the 3.5L V6 is manageable for a confident hobbyist, but improper torque or damaged components can lead to misfires or leaks.
- Do-it-yourself: Pros - lower cost, educational value; Cons - risk of cross-threading, mis-torquing, or missing hidden issues; may void some warranties if applicable.
- Professional service: Pros - proper torque, correct gap, diagnostics included; Cons - higher upfront cost, scheduling considerations.
Conclusion: For many GS 350 owners, a reputable independent shop offers a good balance of cost and reliability, while dealerships provide OEM parts and warranties but at higher prices.
Maintenance interval and benefits
Replacing spark plugs at the manufacturer-recommended interval helps maintain engine efficiency, performance, and fuel economy. For the 2GR-FSE engine in the 2013 GS 350, the typical interval is around 100,000 miles, though you should verify this in your owner's manual. Driving style, fuel quality, and engine condition can influence wear and replacement timing.
How to save money on spark plug replacement
Smart planning can reduce costs without sacrificing quality. Consider these tips when budgeting for the service:
- Get quotes from multiple shops and ask for parts and labor separately.
- Choose aftermarket or OEM-equivalent plugs that meet Lexus specifications; ensure the heat range is correct.
- Combine the spark plug service with other routine maintenance to reduce labor overhead.
- Ask about bundled pricing, coupons, or flat-rate six-plug replacements.
- Check for any eligible recalls or service campaigns related to ignition components.
Conclusion: Being proactive with price comparisons and sticking to recommended parts helps keep the job affordable without compromising reliability.
Summary
For a 2013 Lexus GS 350, replacing all six spark plugs typically falls in the $300–$600 range, with parts roughly $60–$150 and labor around $120–$375 depending on shop rate and location. Dealer quotes can exceed these figures. Coils or related components are rarely needed unless faults are found. Whether you DIY or hire a shop, pricing will vary by region, part choice, and whether additional services are performed.
How much does Lexus charge to change spark plugs?
The cost to replace Lexus spark plugs can range from $400 to over $1,100, with an average around $400 to $700 at an independent shop. A major factor is how accessible the spark plugs are—some Lexus models, like certain IS and ES sedans, have spark plugs buried under components that add significant labor time and cost, potentially pushing the total well over $1,000.

Cost breakdown
- Parts: 6 to 8 spark plugs, which can cost around $10 to $25 each depending on the material (e.g., iridium or platinum), plus any necessary gaskets or other parts.
- Labor: The price is highly variable, depending on how long it takes to access the plugs. It can be as low as a few hours or several, pushing the cost up significantly for models with more complex engine designs.
- Dealer vs. independent shop: Dealerships typically charge more, while independent shops can offer more competitive rates. You may find an independent shop willing to do the work for $100-$200 in labor if the spark plugs are easy to access.
- Other factors: The final price will also depend on your location and the specific parts (like OEM vs. aftermarket) used. If the mechanic recommends replacing other parts, like coils, at the same time, this will also increase the total cost.
How often should Lexus spark plugs be changed?
Lexus spark plug replacement intervals vary by model and spark plug type, but generally range from 60,000 to 100,000 miles. Newer models with iridium or titanium plugs typically have a longer interval, often around 100,000 miles or more, while some earlier models or specific engines may recommend replacement every 60,000 miles. Always check your vehicle's owner's manual or scheduled maintenance guide for the most accurate information.
General guidelines
- Modern Lexus with iridium or titanium plugs: Replacement is often recommended every 100,000 miles.
- Specific models: Some Lexus models, even newer ones, may have a 60,000-mile interval, so it's important to check the specific maintenance schedule.
- Signs of worn plugs: Regardless of the interval, you may need to replace them sooner if you experience symptoms like engine misfires, reduced fuel efficiency, difficulty starting, or poor acceleration.
How to find your specific interval
- Consult your owner's manual: This is the most reliable source for your vehicle's specific maintenance schedule.
- Check your Scheduled Maintenance Guide: This document will provide detailed information on when components like spark plugs should be serviced.
- Ask a certified technician: A Lexus technician can provide expert advice for your specific make and model.
How many miles will a 2013 Lexus GS350 last?
A 2013 Lexus GS 350 can last 200,000 to 300,000 miles or more with proper maintenance, though some owners have reported reaching 350,000 to 400,000 miles. While the engine and transmission are very durable, it is important to expect and budget for wear on other parts like suspension components and shocks, which will need replacement eventually.
Factors influencing lifespan
