APR Z1004081 Iridium Pro Spark Plugs Thread Reach Heat Range - 12mm 26.5mm 10

The APR Z1004081 Iridium Pro Spark Plugs are precision-engineered performance spark plugs designed for high-performance and modified engines requiring a colder heat range. Featuring advanced iridium electrode technology, these spark plugs deliver superior ignition performance, extended service life, and improved throttle response compared to traditional copper or platinum plugs.

Key Specifications:

• Thread Diameter: 12mm
• Thread Reach: 26.5mm
• Hex Size: 14mm
• Heat Range: 10 (colder heat range for forced induction and high-compression applications)
• Seat Type: Gasket seat
• Supplied Gap: 0.55mm ± 0.05mm
• Installation Torque: 17 Nm

Features and Benefits:

• Iridium electrode provides exceptional durability and consistent spark performance
• Non-projected insulator design for specific combustion chamber geometries
• Lower required voltage for reliable ignition even under demanding conditions
• High-quality ceramic insulator material for excellent heat dissipation
• Manufactured in the European Union to strict quality standards

These spark plugs are ideal for turbocharged, supercharged, or high-compression engines where a colder heat range is necessary to prevent pre-ignition and detonation. The precise 12x26.5x14mm dimensions ensure proper fitment in compatible cylinder heads.
