Superior Material Construction and Durability
Premium performance spark plugs distinguish themselves through their exceptional material composition and construction techniques. The use of precious metals like iridium and platinum in the center electrode represents a significant advancement over traditional copper plugs. These materials exhibit remarkable wear resistance, maintaining their precise dimensions and performance characteristics over extended periods. The fine-wire center electrodes, typically measuring 0.4mm to 0.6mm, demonstrate outstanding durability while promoting more efficient ionization of the air-fuel mixture. The ground electrodes often incorporate special alloys that resist erosion and maintain optimal gap settings even under high-compression environments. This superior construction translates to extended service intervals, often reaching 100,000 miles before replacement becomes necessary.
