Understanding Spark Plug Technology
Before we delve deeper into Denso’s offerings, it’s essential to grasp the fundamental principles behind spark plug technology. A spark plug is essentially an electrical insulator with a central electrode and a ground electrode, separated by a small gap. When a high-voltage electrical current passes through this gap, it creates a spark that ignites the compressed air-fuel mixture in the engine’s combustion chamber.
Several factors influence the performance and lifespan of a spark plug:
- Electrode Material:
- Gap Size:
- Insulator Material:
- Heat Range:
Spark plug electrodes are typically made from precious metals like platinum, iridium, or palladium, or from nickel alloys. Precious metals offer superior durability and resistance to wear and tear, extending the spark plug’s lifespan.
The gap between the electrodes determines the voltage required to create a spark. A narrower gap requires less voltage, resulting in a hotter spark and improved fuel efficiency. However, a narrower gap is also more susceptible to fouling.
The insulator, typically made from ceramic, prevents electrical arcing between the electrodes. The insulator’s material and design influence its resistance to heat and electrical breakdown.
The heat range refers to the spark plug’s ability to dissipate heat. A hotter spark plug has a lower heat range and is better suited for high-performance engines, while a cooler spark plug has a higher heat range and is ideal for engines that operate under moderate conditions.

Frequently Asked Questions
What is the difference between platinum and iridium spark plugs?
Both platinum and iridium spark plugs offer superior durability and performance compared to standard nickel spark plugs. Iridium spark plugs utilize a fine-wire iridium center electrode, which is even more durable and wear-resistant than platinum. This allows for a narrower gap, resulting in a hotter spark and improved fuel efficiency. Platinum spark plugs, while still durable, generally have a wider gap and may not offer the same level of performance as iridium plugs. (See Also: How Long Should Spark Plugs Last? – Ultimate Guide)
