APR Ignition Coil & Spark Plug Kit (2.0T/2.5T 9A2 4-cylinder engines) | KT100037

The APR Ignition Coil & Spark Plug Kit (KT100037) is a high-performance ignition refresh designed specifically for Porsche 2.0T and 2.5T 9A2 4-cylinder engines. This kit pairs APR High-Output Ignition Coils with APR Iridium Pro Spark Plugs to deliver a stronger, more consistent spark. By increasing energy output by up to 17% over stock, this system is engineered to support the intense cylinder pressures of tuned Porsche engines, ensuring reliable performance under high boost and extreme thermal loads.

The included Heat Range 9 Iridium Pro Spark Plugs feature a projected insulator design and an iridium electrode with a 152% higher melting point than silver. This setup provides superior resistance to pre-ignition and spark blowout, making this kit an essential upgrade for 718 Boxster/Cayman owners running Stage 1, Stage 2, or high-ethanol (E85) tunes.

Key Features:

• System Engineering: Matched coils and plugs designed to work in harmony for a complete ignition overhaul in one box.
• 17% Higher Energy Output: Significantly enhanced output via increased copper winding diameter and stronger neodymium magnets for a more powerful spark.
• Iridium Pro Technology: Features an iridium electrode and copper core construction for maximum heat dissipation and efficient firing.
• Extreme Durability: Coils are batch-tested to over 15 million firings (73+ hours), ensuring elite reliability for high-power applications.
• Ethanol Optimized: Specialized electrode design makes it easier to ignite "hard-to-light" fuels like E85 while resisting pre-ignition.
• Direct Plug-and-Play: No wiring or coding required; installs exactly like factory components for a simple DIY upgrade.
