APR Ignition Coil & Spark Plug Kit (2.0T EA888.3, EA888.4 4-cylinder engines)

The APR Coils & Plugs Pack is a complete ignition refresh solution designed to provide a stronger, more consistent spark for 4-cylinder Volkswagen, Audi, and Porsche engines. This kit pairs APR High-Output Ignition Coils with APR Iridium Pro Spark Plugs, specifically selected to eliminate spark blowout and ignition breakup in high-performance and tuned applications. Whether you are running a stock engine or a high-boost Stage 2+ build, this direct-fit upgrade ensures a smoother idle, sharper throttle response, and maximum reliability under heavy load.

By increasing energy output by up to 14% over stock, APR coils provide the necessary voltage to jump the gap even as cylinder pressures rise. The Heat Range 9 Iridium Pro Spark Plugs feature a superior melting point compared to platinum or silver, offering a cooler operating temperature and better resistance to pre-ignition—making them the perfect choice for vehicles running upgraded turbochargers or ethanol-blended fuels (E85).

Key Features:

• Increased Spark Energy: APR coils deliver 14% more energy than OEM units via increased copper winding diameter and stronger neodymium magnets.
• Iridium Pro Spark Plugs: Heat Range 9 plugs designed for high-heat, high-load conditions with 152% higher melting point than silver.
• Refined Combustion: Optimized electrode design supports stable combustion for hard-to-ignite fuels like ethanol.
• Direct-Fit DIY Install: True plug-and-play upgrade with no wiring, coding, or tuning changes required.
• Durability Tested: Coils are batch-tested to over 15 million firings (73+ hours) to ensure long-term reliability.
• Aesthetic Options: Available in Red, Blue, or Grey housings to customize your engine bay.
