APR Ignition Coil & Spark Plug Kit (2.5T EA855.2 5-cylinder engines)

The APR Coils & Plugs Pack (5-Cylinder) is a comprehensive ignition refresh specifically engineered for the Audi 2.5T EA855 EVO and other high-performance 5-cylinder VAG engines. This kit pairs APR High-Output Ignition Coils with APR Iridium Pro Spark Plugs, delivering a stronger, more consistent spark to support the high cylinder pressures of tuned or heavily modified engines. Whether you’re running a stock daily driver or a Stage 3 monster, this direct-fit upgrade eliminates ignition breakup and ensures reliable performance under extreme heat and load.

By increasing energy output by up to 14% over stock, APR coils provide the extra voltage needed for a clean burn in high-boost scenarios. The Heat Range 9 Iridium Pro Spark Plugs offer a significantly higher melting point than standard silver or platinum plugs, providing superior resistance to pre-ignition—especially critical for vehicles running ethanol (E85) or large turbocharger upgrades.

Key Features:

• Optimized for 5-Cylinder Engines: Specifically curated for 2.5T applications like the Audi RS3 and TT RS.
• 14% Increased Energy: Higher energy output than factory coils via increased copper winding diameter and stronger neodymium magnets.
• Iridium Pro Performance: Heat Range 9 plugs with an iridium electrode that requires less voltage to fire and handles extreme temperatures.
• Direct Plug-and-Play: Direct replacement for factory coils and plugs with no wiring, coding, or tuning changes required.
• High-Heat Durability: Copper core construction for efficient heat dissipation and batch-tested coils to ensure long-term reliability.
• Color Customization: Available in Red, Blue, or Grey to match your engine bay aesthetic.
