20 Best Spark Plugs For A 383 Stroker With Aluminum Heads (2022 Updated)

Spark plugs are devices that create a spark of electricity in order to ignite the air/fuel mixture in the engine cylinder. In order to create this spark, the spark plug must be made of a material that can withstand the high temperatures and pressures inside the engine.

The most common material used for spark plugs is iridium. Iridium is a very strong and durable metal that can withstand the high temperatures and pressures inside the engine.
