When modifying an engine, many focus on intake, exhaust, and ignition components, but often overlook the importance of spark plugs. Different modifications require specific spark plugs to maximize performance and prevent potential issues.
1. Best Spark Plug Choices for High-Performance Cars
- Turbocharged/Supercharged Engines: Use iridium or double-iridium spark plugs, as they can withstand higher combustion pressures and provide stable ignition.
- High-Compression Naturally Aspirated Engines: Platinum or iridium spark plugs ensure complete combustion due to their strong spark and high conductivity.
- Racing or Extreme Performance Builds: Cold spark plugs help prevent engine knocking under high RPM conditions.
2. Adjusting Spark Plug Gaps for Modifications
After modifications, adjustments to the spark plug gap may be necessary due to changes in air intake or fuel mixture. For turbocharged engines, a smaller gap is often needed to ensure reliable ignition under high cylinder pressure.
Choosing the right spark plug based on the modification type helps maximize engine performance and prevent ignition-related failures.
