Hotter Than a Lightning Bolt

When the voltage from the ignition coil reaches the spark plug, it arcs across the spark gap, creating a spark hotter than a lightning bolt (okay, maybe not that hot, but still impressive!). This spark ignites the air-fuel mixture in the combustion chamber, setting off a controlled explosion that powers your car.

The Evolution of Spark Plugs

Now, you might be thinking, “Do all spark plugs require the same voltage?” Well, not exactly. The voltage requirements can vary depending on the design and technology of the spark plug. In recent years, advancements in spark plug technology have led to the development of iridium and platinum spark plugs.

The Iridium and Platinum Spark Plug Twist

Iridium and platinum spark plugs have a special twist – they require less voltage to create a spark, thanks to their enhanced conductivity. So, if your vehicle is equipped with these high-performance spark plugs, you might see voltage requirements in the ballpark of 5,000 to 10,000 volts.

The Bottom Line

In conclusion, spark plugs need a hefty voltage punch to create the spark that sets your car’s engine roaring. With the standard range falling between 10,000 to 30,000 volts, these little dynamos work hard to keep your wheels turning. Whether you’re cruising down the highway or stuck in bumper-to-bumper traffic, never underestimate the electrifying power of those spark plugs. Keep them happy, and they’ll keep your engine purring like a contented kitten.
