Types of Spark Plugs
Spark plugs are primarily categorized based on the material they are made from. The primary types include copper/nickel, iridium, platinum, and double platinum. Each type has its unique attributes in terms of longevity, performance, and cost.

1. Copper Spark Plugs

• Pros: Affordable, suitable for older models (pre-1980), efficient in turbocharged motors, ideal for high-compression situations.
• Cons: Shorter lifespan, higher voltage requirement.

2. Iridium Spark Plugs

• Pros: Ensures complete combustion, requires less voltage, longer lifespan.
• Cons: More expensive than other types.

3. Platinum Spark Plugs

• Pros: Longer lasting than copper plugs, minimal carbon buildup.
• Cons: Pricier than copper plugs.

4. Double Platinum Spark Plugs

• Pros: Ideal for wasted spark ignitions, durable, reliable performance.
• Cons: Expensive.

Comparing Spark Plug Types

• Performance: Copper plugs offer the best conductivity and cooler operation, while iridium outperforms platinum.
• Lifespan: Iridium spark plugs typically last the longest.
• Cost: Copper is the most affordable, while iridium is the most expensive.
• System Compatibility: Each type is designed for specific vehicle configurations.

Which Spark Plug Type Is Better?
Your choice should be guided by the manufacturer's recommendation. Avoid using copper plugs in coil-on-plug systems and be cautious about downgrading from OEM suggestions.

Understanding the different types of spark plugs and their respective benefits is crucial for optimal car maintenance. Always refer to your vehicle's manual for specific recommendations and choose spark plugs that match your car’s requirements and your maintenance goals.
