Maintaining your 2017 Hyundai Elantra is crucial for optimal performance and fuel efficiency. One often-overlooked component that plays a vital role is the spark plug. This guide provides detailed information on spark plugs for your Elantra, covering replacement, types, and factors to consider when choosing the best ones for your vehicle.
Spark plugs are essential for igniting the air-fuel mixture in your engine's cylinders, initiating the combustion process. Over time, spark plugs degrade due to wear and tear from the intense heat and electrical activity within the engine. Replacing them at the recommended intervals is a cost-effective way to prevent engine misfires, poor fuel economy, and other performance issues.
Why Spark Plugs Matter
The primary function of a spark plug is to ignite the air-fuel mixture within the engine's combustion chamber. This ignition initiates the power stroke that drives your car's pistons and, ultimately, your vehicle's movement. Worn or faulty spark plugs can lead to significant problems, impacting your car’s overall performance.
Beyond simply igniting the fuel, spark plugs contribute to fuel efficiency and emissions control. Properly functioning spark plugs ensure that the fuel burns efficiently, minimizing wasted fuel and reducing harmful emissions. Thus, replacing them regularly can have a positive impact on both your wallet and the environment.
When to Replace Spark Plugs in Your 2017 Elantra
Hyundai recommends specific replacement intervals for spark plugs in the 2017 Elantra. These recommendations are usually found in your owner's manual or by consulting a trusted mechanic. Ignoring these recommendations can result in decreased performance and potentially more significant engine problems down the line.
In general, spark plugs should be replaced every 60,000 to 100,000 miles, although this can vary depending on the type of spark plug installed. It's always a good practice to check your owner's manual for the most accurate and up-to-date recommendations. Additionally, pay attention to any performance issues that may suggest premature spark plug failure, such as rough idling or reduced fuel economy.
Types of Spark Plugs for Your Elantra
Several types of spark plugs are available for your 2017 Hyundai Elantra, each with its own benefits. Understanding the differences between these types can help you make an informed decision when it comes to replacing them.
The most common types include copper, platinum, and iridium spark plugs. Copper spark plugs are typically the most affordable, but they may need to be replaced more frequently. Platinum and iridium spark plugs offer greater durability and longevity, and often provide better performance, making them a good long-term investment.
Copper Spark Plugs
Copper spark plugs are often chosen for their affordability. They feature a copper core to enhance conductivity. However, they tend to wear out quicker than other options, usually requiring replacement between 20,000-40,000 miles.
While inexpensive, the frequent replacement needs can make them less cost-effective over the long run for certain drivers. They are a suitable option if you're on a budget and don't mind the added maintenance.
Platinum Spark Plugs
Platinum spark plugs offer increased durability compared to copper plugs. They feature a platinum tip that resists wear and erosion, extending their lifespan. You can typically expect them to last between 60,000 and 80,000 miles.
Platinum plugs provide a good balance between performance and longevity. They are a solid choice for those seeking improved performance and longer replacement intervals without spending too much.
Iridium Spark Plugs
Iridium spark plugs are the premium option, known for their exceptional durability and performance. They feature an iridium tip, the hardest metal used in spark plugs, enabling superior resistance to wear. Their lifespan often extends beyond 100,000 miles.
Iridium spark plugs offer the best performance, fuel efficiency, and longevity. Although they are the most expensive upfront, their extended lifespan often justifies the higher cost, making them a popular choice for many car owners.
Replacing Spark Plugs: A Step-by-Step Guide
Replacing spark plugs can be a straightforward DIY project if you have some basic mechanical skills. However, if you are not comfortable with car maintenance, it's always best to have a qualified mechanic perform the replacement. Safety is paramount when working with automotive components.
Before starting, gather the necessary tools, including a spark plug socket, ratchet, torque wrench, and the new spark plugs. Always disconnect the negative battery terminal before starting any work on your car's electrical system to avoid shocks and accidental ignition.

1. **Locate the Spark Plugs:** Consult your Elantra's owner's manual for the exact location of the spark plugs, typically accessible under the hood. Remove any covers or components that obstruct access.
2. **Disconnect the Wires/Coils:** Carefully disconnect the spark plug wires (or ignition coils, if your Elantra uses coil-on-plug ignition) from each spark plug. Be sure to note the order in which the wires are connected for easy reassembly.
3. **Remove the Old Spark Plugs:** Use the spark plug socket and ratchet to loosen and remove the old spark plugs. Work gently to avoid damaging the threads in the cylinder head.
4. **Inspect and Gap the New Plugs:** Before installing the new spark plugs, inspect them for any damage. If necessary, use a spark plug gapping tool to adjust the gap according to the specifications in your owner's manual.
5. **Install the New Spark Plugs:** Carefully thread the new spark plugs into the cylinder head by hand to avoid cross-threading. Then, tighten them to the manufacturer's recommended torque using a torque wrench. Over-tightening can damage the spark plugs or the cylinder head.
6. **Reattach the Wires/Coils:** Reconnect the spark plug wires (or ignition coils) to the new spark plugs, ensuring that they are securely connected and in the correct order.
7. **Reassemble Components:** Reinstall any covers or components you removed earlier.
8. **Reconnect the Battery:** Reconnect the negative battery terminal.
9. **Start the Engine:** Start the engine and listen for any unusual sounds or misfires. If everything runs smoothly, your spark plug replacement is complete!
Choosing the Right Spark Plugs
Selecting the right spark plugs for your 2017 Hyundai Elantra is essential. Consult your owner's manual for the recommended spark plug type and specifications. Using the wrong spark plugs can lead to engine performance issues and even damage.
Consider your driving habits and budget when choosing between copper, platinum, and iridium spark plugs. Iridium plugs provide the best performance and longevity but are more expensive. Platinum plugs offer a good balance between performance and cost, while copper plugs are the most affordable option. Ultimately, choose the spark plug type that aligns best with your needs and budget.
Signs of Bad Spark Plugs
Identifying the symptoms of failing spark plugs helps you address the issue promptly, preventing potential engine damage. Common signs indicate the need for replacement.
These signs include: difficulty starting the engine, rough idling, misfires, reduced fuel economy, and poor acceleration. If you notice any of these symptoms, it's wise to inspect your spark plugs. Furthermore, a check engine light often accompanies spark plug problems; a diagnostic test can help pinpoint the issue.
Conclusion
Maintaining your 2017 Hyundai Elantra's spark plugs is a crucial aspect of vehicle upkeep, influencing both engine performance and longevity. By understanding the different types of spark plugs, replacement intervals, and installation processes, you can ensure that your Elantra operates at its best.
