Our Top 7 Best Spark Plugs For 2017 Toyota Tacoma Reviews – Expert Tested & Recommended
1. Denso Iridium TT Spark Plugs for Toyota Tacoma 2.7L L4
🌟 Key Features That Stand Out
- ✓ Twin-Tip Technology: Uses a 1.1mm platinum center electrode and a titanium ground electrode for a larger spark.
- ✓ Superior Fuel Economy: Better combustion efficiency means you get more miles out of every tank of gas.
- ✓ OEM Compatibility: Designed as a direct replacement for 2005-2017 Tacoma 2.7L L4 models.
- ✓ Extreme Durability: Built to handle high compression levels and deliver consistent energy.
💡 Why We Recommend It
The Denso Iridium TT is our top pick because Denso is often the original equipment manufacturer for Toyota. This means you are getting a plug that was literally designed for your truck’s engine. The “Twin-Tip” design is a game-changer; it focuses the spark more effectively than standard plugs, which leads to smoother idling and noticeably better throttle response.
If you use your Tacoma as a daily driver, these plugs are a smart investment. They are built to last a long time, often exceeding standard service intervals, so you won’t have to worry about changing them again for a very long time. They are particularly good for those who live in colder climates where reliable starting is a must.
🎯 Best For
This product is ideal for: Tacoma owners with the 2.7L engine who want factory-level quality and the best possible fuel efficiency.
⚖️ Pros and Cons
✅ Pros
- Excellent fuel economy gains
- Genuine OE quality replacement
- Very long lifespan (up to 100k miles)
- Improves cold weather starting
❌ Cons
- Higher price point per plug
- Not compatible with 3.5L V6 engine
💬 What Customers Say
“My 2017 Tacoma 2.7L was idling a bit rough. Swapped these in and it smoothed right out. I also noticed about a 1.5 mpg increase on my commute.”
— Verified Buyer
“You can’t go wrong with Denso in a Toyota. These are high-quality plugs that fit perfectly and made the truck feel much more responsive.”
— Verified Buyer
2. A-Premium Ignition Coil Pack and Iridium Spark Plugs for V6 Tacoma
🌟 Key Features That Stand Out
- ✓ Complete Tune-Up Kit: Includes 6 high-performance ignition coils and 6 Iridium spark plugs.
- ✓ V6 Optimization: Specifically designed for the 3.5L V6 engine found in 2016-2021 Tacomas.
- ✓ Triple Longevity: Iridium material extends spark plug life nearly threefold compared to copper.
- ✓ Improved Ignition: Coils are bolt-on design for easy installation and reliable electrical connection.
💡 Why We Recommend It
If you are doing a 100,000-mile service on your V6 Tacoma, we highly recommend this A-Premium kit. Often, when spark plugs start to fail, the ignition coils are also nearing the end of their lifespan. By replacing both at the same time, you save on labor and prevent future misfires that can leave you stranded.
The quality of the iridium in these plugs ensures a very stable idle speed. This is especially important for the 3.5L engine, which uses a complex Atkinson cycle and needs precise ignition to run efficiently. This kit offers incredible value compared to buying coils and plugs separately from a dealership.
🎯 Best For
This product is ideal for: Tacoma V6 owners who want a total ignition overhaul to restore power and fuel economy.
⚖️ Pros and Cons
✅ Pros
- Full kit saves time and money
- High-quality iridium construction
- Reduces engine emissions
- 1-year unlimited mileage guarantee
❌ Cons
- Higher initial cost for the kit
- More complex install than just plugs
💬 What Customers Say
“Perfect fit for my 2017 TRD Off-Road. It fixed a persistent misfire under heavy load. Great price for coils and plugs together.”
— Verified Buyer
“The truck starts up much faster now. I was worried about non-OEM coils, but these feel solid and have been working great for months.”
— Verified Buyer
3. A-Premium Double Iridium Spark Plugs for Toyota Tacoma 2016-2020
🌟 Key Features That Stand Out
- ✓ Double Iridium Design: Features iridium on both the center and ground electrode for maximum life.
- ✓ 100k+ Mile Interval: Specifically recommended for replacement every 100,000 to 120,000 miles.
- ✓ Factory Pre-Gapped: Comes with a 0.032-inch gap, ideal for the 2.7L engine.
- ✓ Maximum Ignitability: Engineered alongside OEM standards for consistent performance.
💡 Why We Recommend It
For the budget-conscious owner who still wants a premium material, these Double Iridium plugs from A-Premium are hard to beat. “Double Iridium” means the spark has to jump between two precious metal surfaces, which drastically reduces wear over time. This leads to a plug that maintains its gap much longer than standard single-precious-metal plugs.
These are particularly well-suited for the 2.7L 2016-2020 Tacoma models. They provide a very cost-effective way to get high-end technology into your truck without the high-end price tag. They are reliable, easy to install, and provide the longevity you expect from a modern truck component.
🎯 Best For
This product is ideal for: Value-seekers who want 100,000-mile spark plugs without the steep cost of name-brand OEM parts.
⚖️ Pros and Cons
✅ Pros
- Very affordable price point
- Double iridium lasts longer than single
- Pre-gapped for easy installation
- High resistance to corrosion
❌ Cons
- Newer brand compared to NGK or Denso
- Limited to 2.7L engine models
💬 What Customers Say
“Installed these on my 2.7 Tacoma. They were gapped perfectly right out of the box and the truck runs great.”
— Verified Buyer
“Hard to beat for the price. I’ve had them in for 5,000 miles now and haven’t had a single issue.”
— Verified Buyer
4. A-Premium 6619 Iridium Platinum Spark Plugs for Tacoma and Highlander
🌟 Key Features That Stand Out
- ✓ Hybrid Metal Build: Iridium center electrode tip with a platinum core for balanced performance.
- ✓ Wide Fitment: Compatible with a massive range of Toyota vehicles, including 2005-2015 Tacomas.
- ✓ 80k-100k Mile Range: Recommended for long-term use without performance degradation.
- ✓ Trivalent Plating: Provides superior anti-corrosion and anti-seizing properties for the life of the plug.
💡 Why We Recommend It
These hybrid plugs offer a fantastic balance between cost and performance. By using an iridium tip and a platinum core, they provide the fast, clean spark of iridium with the heat-conducting properties of platinum. This combination is great for keeping the engine temperature stable during long highway drives.
What makes these stand out is their versatility. If you have several Toyota vehicles in your driveway, there’s a good chance these will fit more than just your Tacoma. They are reliable, sturdy, and offer a consistent spark that helps reduce engine emissions and improves daily driveability.
🎯 Best For
This product is ideal for: Beginners looking for a reliable, well-rounded plug that fits multiple Toyota platforms.
⚖️ Pros and Cons
✅ Pros
- Consistent performance over 80k miles
- High resistance to electrical erosion
- Very broad vehicle compatibility
- Solid heat transfer properties
❌ Cons
- Gap may need slight adjustment for 2017+ models
- Not quite as durable as full double-iridium
💬 What Customers Say
“Replaced my old plugs with these and the difference in idle is like night and day. Much smoother and quieter.”
— Verified Buyer
“Good quality plugs. I used them in my Tacoma and my wife’s RAV4. Both vehicles are running great.”
— Verified Buyer
5. Autolite Platinum Spark Plugs for Toyota Tacoma 3.5L and 4.0L V6
🌟 Key Features That Stand Out
- ✓ Necked-Down Center Electrode: Fires quicker and cleaner with less voltage for easier starts.
- ✓ Yttrium-Enhanced Ground: Provides superior heat transfer and resists high-heat degradation.
- ✓ Platinum-to-Platinum Firing: Ensures virtually no gap erosion for a much longer service life.
- ✓ Full 6-Pack Set: Conveniently packaged for V6 engine requirements.
💡 Why We Recommend It
Autolite is a household name in spark plugs, and for good reason. These Platinum series plugs are specifically designed to provide high-voltage performance with lower energy requirements from your coils. This is great for older trucks where the ignition system might not be as strong as it once was.
The platinum-to-platinum design is the star here. It means both the center and the ground electrodes are reinforced, so the gap stays precise for a long time. If you use your Tacoma for heavy towing or off-roading, you’ll appreciate the heat resistance that the Yttrium-enhanced electrode provides.
🎯 Best For
This product is ideal for: Heavy-use Tacoma V6 owners who need a plug that can handle high engine temperatures and towing.
⚖️ Pros and Cons
✅ Pros
- Excellent for high-heat conditions
- Requires less voltage to fire
- Trusted brand with decades of experience
- Noticeably faster engine starts
❌ Cons
- Platinum isn’t quite as conductive as iridium
- Slightly more gap erosion over very long periods
💬 What Customers Say
“I’ve used Autolite in all my vehicles for years. These platinum ones are perfect for my Tacoma. No more stumbling at stoplights.”
— Verified Buyer
“A solid 6-pack for the V6. Installation was easy and they were gapped correctly right out of the box.”
— Verified Buyer
6. NGK 7090 G-Power Platinum Spark Plugs BKR5EGP 6-Piece Set
🌟 Key Features That Stand Out
- ✓ Trapezoid Cut Ground: Reduces “quenching,” allowing the spark flame to grow larger and faster.
- ✓ Trivalent Metal Plating: Superior protection against rust and seized threads in the cylinder head.
- ✓ Corrugated Ribs: Specially designed to prevent “flashover,” where energy leaks down the outside of the plug.
- ✓ Alumina Silicate Ceramic: High-grade insulator ensures better heat transfer and overall strength.
💡 Why We Recommend It
NGK is arguably the most famous name in spark plugs worldwide. Their G-Power series is a performance platinum plug that offers a massive upgrade over standard copper at a very reasonable price. The trapezoid cut ground electrode is a clever bit of engineering; it helps the flame of the combustion spread more quickly, giving you a slightly punchier engine feel.
These are excellent for daily drivers who want a “set it and forget it” solution. They are highly resistant to fouling, meaning they stay cleaner for longer, even if you do a lot of short-trip city driving. They are a reliable, high-performance option that won’t break the bank.
🎯 Best For
This product is ideal for: Daily commuters who want an affordable, high-performance upgrade from a world-renowned brand.
⚖️ Pros and Cons
✅ Pros
- Very reliable engine performance
- Excellent price-to-quality ratio
- Prevents seized plugs in the head
- Reduced emissions and better MPG
❌ Cons
- Platinum life is shorter than Iridium
- Not the absolute highest performance NGK offers
💬 What Customers Say
“NGK is the only brand I trust. These G-Power plugs made my Tacoma run like it was new. Very smooth idle.”
— Verified Buyer
“Great plugs for a great price. Noticed a slight improvement in gas mileage right away.”
— Verified Buyer
7. Champion Iridium Spark Plugs for Toyota Tacoma 3.5L V6
🌟 Key Features That Stand Out
- ✓ Durable Precious Metals: Built with high-grade iridium to minimize wear and tear over long periods.
- ✓ Racing Heritage: Leverages Champion’s innovations from the race track for a more reliable daily spark.
- ✓ OE-Quality Replacement: Adheres to the toughest industry standards for a perfect fit in V6 engines.
- ✓ Long Service Life: Engineered to meet modern engine demands for power and longevity.
💡 Why We Recommend It
Champion has been a leader in ignition technology for over a century. These Iridium plugs are a great choice for the 3.5L Tacoma V6 because they are designed to handle the high-heat cycles of modern engines. If you’ve ever felt like your truck is struggling under a full load, these plugs can help provide the consistent spark needed for peak power.
One of the best things about Champion is their fitment accuracy. These are direct replacements, so you won’t be struggling with weird thread patterns or incorrect reach. They are reliable, powerful, and backed by a brand that powers everything from lawnmowers to professional race cars.
🎯 Best For
This product is ideal for: Professionals and high-mileage drivers who need a heavy-duty, reliable ignition source.
⚖️ Pros and Cons
✅ Pros
- Very durable precious metal build
- Improves engine responsiveness
- Excellent thread quality and fit
- Highly reliable brand name
❌ Cons
- Higher price point than basic plugs
- V6 kit can be expensive
💬 What Customers Say

— Verified Buyer
“Quality seems top-notch. These have been in my truck for 10k miles now and it’s running perfectly.”

Complete Buying Guide for Best Spark Plugs For 2017 Toyota Tacoma
Essential Factors We Consider
When you are looking for the right spark plugs, the material is the most important factor. Iridium is the top choice for the 2017 Tacoma because it is extremely hard and has a very high melting point. This allows for a thinner center electrode, which makes the spark more consistent. Platinum is a good second choice, offering long life at a slightly lower price point. We also consider the “reach” and thread size to ensure the plug sits perfectly in the combustion chamber without hitting the piston or being too far away to ignite the fuel properly.
Budget Planning
For a basic set of four plugs for the 2.7L engine, expect to spend between $20 and $50. If you have the V6, you will need six plugs, and if you choose to replace the ignition coils as well, a full kit can cost between $100 and $150. While it might be tempting to go with the cheapest copper plugs, keep in mind that you will have to replace them much more often, which actually costs more in the long run due to labor or your own time.
Final Thoughts
Replacing your spark plugs is one of the most rewarding DIY tasks you can do for your truck. It is relatively simple and provides immediate results in how the vehicle feels. Always double-check your engine type (2.7L vs 3.5L) before ordering, and if you haven’t changed your coils in over 100,000 miles, consider doing them at the same time to ensure your ignition system is at 100%.
Frequently Asked Questions
Q: How often should I change the spark plugs in my 2017 Tacoma?
A: For most 2017 Tacoma models, Toyota recommends changing the spark plugs every 100,000 to 120,000 miles if you are using Iridium plugs. However, if you notice a rough idle or poor gas mileage, you might want to check them sooner.
Q: What is the correct gap for 2017 Toyota Tacoma spark plugs?
A: The standard gap is usually around 0.032 inches for the 2.7L engine and 0.044 inches for the 3.5L V6. Most high-quality plugs like Denso or NGK come pre-gapped, but it is always a good idea to double-check them with a gap tool before installation.
Q: Do I need to replace my ignition coils when I change my plugs?
A: You don’t have to, but it is highly recommended if your truck has over 100,000 miles. Coils can wear out and cause misfires, and since you already have the engine apart to get to the plugs, it’s the perfect time to do both.
Q: Can I use copper spark plugs in my Tacoma?
A: You can, but it’s not recommended. Modern Toyota engines are designed to work with the higher conductivity and heat resistance of Platinum or Iridium. Copper plugs will wear out much faster, often in less than 30,000 miles.
