Iridium spark plugs last longer than copper and platinum plugs, making them a popular choice for modern vehicles that require high performance.
- Best for: High-performance cars, modern vehicles with advanced ignition systems.
- Advantages: Longer lifespan, better fuel efficiency, reduced emissions.
Platinum Spark Plugs
Platinum spark plugs offer a good balance of performance and affordability. They last longer than copper plugs and provide improved engine performance. While not as durable as iridium, platinum spark plugs are still a great choice for most everyday vehicles.
- Best for: Daily-driven vehicles, older models.
- Advantages: Increased durability, improved ignition, cost-effective.
Copper Spark Plugs
Copper spark plugs are the most affordable option, but they have a shorter lifespan compared to platinum or iridium. Despite this, they provide excellent performance and are ideal for high-performance applications or racing engines.
- Best for: Performance cars, racing engines.
- Advantages: Quick ignition, lower cost, high performance.
V-Power Spark Plugs
NGK’s V-Power spark plugs feature a unique V-groove design on the center electrode, which helps reduce the voltage required to ignite the air-fuel mixture. This leads to improved combustion efficiency and overall engine performance.

How to Choose the Right NGK Spark Plug for Your Vehicle
Selecting the appropriate spark plug for your vehicle can seem tricky, but it doesn’t have to be. Here are the key factors to consider when choosing an NGK spark plug:
Vehicle Make and Model
Always refer to your vehicle’s manual or consult with a mechanic to determine the right spark plug for your engine. NGK offers a comprehensive catalog that allows you to easily find the right spark plug for your vehicle by make and model.
Driving Conditions
If you frequently drive in extreme conditions—such as high temperatures, heavy traffic, or mountainous terrain—you’ll want to opt for a spark plug that can withstand these conditions. Iridium plugs are an excellent choice for harsh environments due to their durability and resistance to wear.
Engine Specifications
Different types of engines require different types of spark plugs. If your car has a high-performance engine, you may need iridium or platinum spark plugs for the best results. For everyday driving, platinum or copper plugs may suffice.
Mileage and Replacement Interval
Consider the mileage of your vehicle and how often you’ve replaced your spark plugs in the past. Iridium spark plugs can last up to 100,000 miles, while copper plugs may need to be replaced every 20,000-30,000 miles.
Signs Your NGK Spark Plugs Need Replacing
Spark plugs don’t last forever. Over time, they wear out and need replacing. Here are some common signs that it might be time to replace your NGK spark plugs:
Poor Fuel Economy
If you notice that you’re filling up more often than usual, it may be due to worn-out spark plugs. When spark plugs aren’t firing correctly, it can lead to incomplete combustion, which affects fuel efficiency.
Rough Idling or Engine Misfires
Worn spark plugs can cause the engine to run roughly, especially at idle. If you experience rough idling or misfires, this could indicate that your spark plugs are malfunctioning.
Difficulty Starting the Engine
When spark plugs begin to fail, starting the engine may become more difficult. If your car cranks but doesn’t start immediately, spark plugs could be the issue.
Engine Hesitation or Poor Acceleration
If the car hesitates when you press the accelerator or struggles to accelerate, it could be due to faulty spark plugs that aren’t firing as they should.
Check Engine Light
Modern vehicles have sensors that can detect when the spark plugs are malfunctioning. If your check engine light turns on, it’s a good idea to check the condition of your spark plugs.
