Turbocharged cars have become increasingly popular among automotive enthusiasts due to their ability to produce significant power from smaller engines. One crucial component that can enhance the performance of these vehicles is the spark plug. This article will guide you through the best spark plugs for turbocharged cars, focusing on options that maximize power while remaining budget-friendly, specifically under $70 per set.
Understanding Spark Plugs in Turbocharged Engines
Spark plugs play a vital role in the combustion process of an engine. In turbocharged engines, the pressure and temperature are higher than in naturally aspirated engines, making the selection of the right spark plug even more critical. Here are some factors to consider:
- Heat Range: Turbo engines generate more heat, so a cooler heat range spark plug is often necessary.
- Material: Copper, platinum, and iridium are common materials, each with different performance characteristics.
- Gap Size: The spark plug gap should be correctly set to ensure optimal ignition timing.
