APR Ignition Coil & Spark Plug Kit (4.0T EA825 8-cylinder engines)

The APR Coils & Plugs Pack (8-Cylinder) is the ultimate ignition overhaul for high-performance Audi and Porsche V8 engines. Specifically matched for the 4.0T and other modern 8-cylinder platforms, this kit pairs APR High-Output Ignition Coils with APR Iridium Pro Spark Plugs. By increasing energy output by 14% over stock, this system ensures a stronger, more consistent spark even under the extreme cylinder pressures of Stage 1 or Stage 2 tuned engines. The result is a smoother idle, crisp throttle response, and the reliability needed to push your V8 to its limit.

The included Heat Range 10 Iridium Pro Spark Plugs are designed for high-heat environments. With a 152% higher melting point than silver, these plugs dissipate heat more efficiently than factory units, preventing pre-ignition and spark blowout during long pulls or track sessions. Whether you are running pump gas or high-octane ethanol blends, this direct-fit upgrade provides the performance and peace of mind your 8-cylinder engine demands.

Key Features:

• V8 System Integration: Matched set of 8 coils and 8 plugs designed to provide a complete, high-output ignition refresh.
• 14% More Spark Energy: Upgraded internal copper windings and neodymium magnets provide significantly more energy than OEM coils.
• Iridium Pro Technology: Features a projected insulator and iridium electrode for lower required voltage and stable combustion.
• Extreme Durability: Coils are batch-tested to over 15 million firings, ensuring elite reliability for high-power applications.
• Cooler Operation: Plugs are designed to operate cooler than stock, resisting pre-ignition and supporting high-load conditions.
• Direct Plug-and-Play: No wiring or coding changes required; compatible with stock or tuned ECU software.
