A Guide to Spark Plugs for the 2019-2024 Toyota Camry
Keep your Camry's engine running smoothly by choosing the right spark plugs for your next service.
- For best results, use OEM-brand (Denso or NGK) Iridium spark plugs.
- The 2.5L 4-cylinder engine has a 120,000-mile replacement interval; the 3.5L V6 is 60,000 miles.
- A flashing check engine light indicates a serious misfire; avoid driving the vehicle to prevent damage.
- Replacement is easy on the 4-cylinder engine but difficult on the rear bank of the V6.
Signs of Failing Spark Plugs
Your Camry's original spark plugs are designed to last a long time, but they will eventually wear out. When they do, you might notice some clear signs that it's time for a replacement. A bad spark plug can't create a good spark, which means fuel doesn't burn properly in the engine.
- Rough Idle: If your car shakes or vibrates when you're stopped at a light, it could be due to worn spark plugs causing unstable engine performance.
- Poor Acceleration: A sluggish or slow response when you press the gas pedal is a common symptom.
- Worse Fuel Economy: When spark plugs are worn, the engine has to work harder and burns more fuel. This can lead to more frequent trips to the gas station.
- Engine Misfires: You might feel a jerking or stumbling from the engine while driving. This is often accompanied by a flashing Check Engine Light and codes like P0300 to P0306.
- Trouble Starting: Worn-out plugs can make it difficult for the engine to start, especially in cold weather.
Choosing the Right Aftermarket Spark Plug
Your 2019-2024 Toyota Camry came from the factory with high-quality Iridium-tipped spark plugs made by either Denso or NGK. When choosing replacements, it's best to stick with these brands for guaranteed compatibility and performance. Aftermarket brands are available, but quality and longevity can vary.
Brand Quality Tiers for Toyota Camry
| Tier | Brands | Description |
|---|---|---|
| OEM / Premium | Denso, NGK | These are the original equipment manufacturers. Choosing their Iridium plugs ensures you get the same quality and lifespan (up to 120,000 miles) as the factory parts. They are the most recommended choice for your Camry. |
| Quality Aftermarket | Bosch | Bosch offers Iridium plugs that are a solid alternative. While not the original brand for Toyota, they are a reputable manufacturer with products that generally meet or exceed OEM standards. Some users prefer to stick with the Japanese OEM brands for Japanese vehicles. |
| Standard / Economy | Autolite, Champion | These brands often provide a more budget-friendly option. While they produce plugs that will work, they may not offer the same longevity or performance as the OEM-grade Iridium plugs. Some mechanics report seeing more electrode wear on these brands over time. For a modern engine like the one in your Camry, investing in premium plugs is usually worth it. |
OEM vs. Aftermarket Spark Plugs for Your Camry
For the 2019-2024 Camry, the original spark plugs are top-tier Iridium units from Denso or NGK. The good news is that you can buy these same exact plugs from aftermarket retailers. There is no quality difference between a Denso plug from a Toyota dealer and a Denso plug from an auto parts store, as long as the part number is correct. Cheaper aftermarket plugs from other brands might save you money upfront, but they may not last as long as the 100,000+ mile interval of the originals, leading to more frequent changes. For peace of mind and the best performance, sticking with OEM-brand Iridium plugs is the safest bet.
Known Issues, Recalls, or TSBs
As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Toyota or the NHTSA related to spark plugs for the 2019-2024 Camry. Issues with spark plugs on these vehicles are almost always related to normal wear and tear from high mileage, not a manufacturing defect. One recall for the 2018-2019 Camry (21TA09) mentioned a potential loss of power braking assist, but this is unrelated to the spark plugs themselves.
Cost of Replacing Toyota Camry Spark Plugs
| Category | Estimated Cost |
|---|---|
| New Aftermarket Parts (per plug) | $4.09 - $33.37 |
| New OEM Parts (per plug) | $14 - $21 |
| Shop Labor Cost | $99 - $227 |
| Total Professional Replacement | $142 - $331+ |
Pro Tip: The cost can be higher for the V6 engine, as the rear three spark plugs are harder to access and require more labor time.
Frequently Asked Questions
When should I replace the spark plugs on my 2019-2024 Toyota Camry?
For the 3.5L V6 (2GR-FKS) engine, Toyota recommends replacing the spark plugs at 60,000 miles. For the 2.5L 4-cylinder (A25A-FKS) engine, the interval is much longer, at 120,000 miles. However, if you experience any symptoms of failure, you should have them checked sooner.
Is it hard to replace the spark plugs on a Toyota Camry myself?
For a 4-cylinder engine, the job is relatively easy and can be done with basic tools in about an hour. The spark plugs are easily accessible on top of the engine. For the V6 engine, the front three plugs are easy, but the rear three are located under the intake manifold, making the job much more difficult and time-consuming. This is often best left to a professional unless you are an experienced DIY mechanic.
Do I need to gap the spark plugs for my Camry?
No. High-quality Iridium and Platinum spark plugs from brands like Denso and NGK come pre-gapped from the factory. Attempting to gap them can damage the fine, brittle electrode. Always verify the part number is correct for your vehicle, and install them directly out of the box.
What is the difference between Iridium and Platinum spark plugs?
Iridium is a harder and more durable material than platinum, with a higher melting point. This allows Iridium plugs to last longer and maintain a precise spark for better performance over their lifespan. Your Camry was designed for Iridium plugs, and it is best to use them for replacement.
