Product Details

The APR Z1003101 Iridium Pro Spark Plugs are engineered for high-performance applications, featuring an advanced iridium electrode that delivers superior durability and ignition efficiency. These spark plugs are specifically designed with a heat range of 9, making them ideal for turbocharged and supercharged engines running higher boost levels or modified fuel maps.

Key Specifications:

  • Thread diameter: 14mm
  • Thread reach: 19mm
  • Hexagon size: 16mm
  • Seat type: Gasket
  • Heat range: 9 (colder plug for high-performance applications)
  • Installation torque: 25 Nm (18.4 lb-ft)

Performance Features:

  • Projected insulator design for improved ignitability and anti-fouling characteristics
  • Iridium electrode construction provides superior strength compared to copper and platinum
  • Lower required ignition voltage for more reliable spark under high-cylinder-pressure conditions
  • Manufactured in the European Union to exacting quality standards
  • Optimized for APR-tuned vehicles and other high-performance applications

These spark plugs are an excellent choice for enthusiasts running upgraded engine management systems or increased boost pressures, where the colder heat range helps prevent pre-ignition and detonation while maintaining reliable combustion.
