Street Series EJ20/25 Ignition Coil Pack Set

The Off the Line Performance Street Series EJ20/25 Ignition Coil Packs are a direct-fit upgrade designed to enhance the ignition system of compatible Subaru EJ20 and EJ25 turbocharged engines. These coil packs generate over 10% more ignition energy compared to OEM coils, leading to improved idle smoothness, consistent power delivery throughout the powerband, and increased reliability, particularly under high-boost conditions. They support wider spark plug gaps for more efficient combustion and are built to prevent misfires even in demanding applications. Installation is straightforward and plug-and-play, requiring no tuning for immediate performance benefits. This makes them suitable for a wide range of vehicles, from daily drivers to highly modified builds capable of 1,000+ horsepower. For tuners, the enhanced spark energy offers greater timing accuracy in the upper RPM range, allowing for more flexibility and potential power gains. They are also adaptable for USDM EJ20 vehicles with black coil packs, though this requires a coil boot swap and dwell adjustment. Fitment is specified for the EJ25 platform, including the 2002-2014 Subaru WRX and 2004-2021 Subaru WRX STI. The EJ20 platform includes the 1989-1993 Subaru Legacy RS, RS-RA, and GT. Note that for 2002-2007 WRX models, the stock coil pack boots must be reused. The package includes four Street Series EJ20/EJ25 Ignition Coils, a product info card, and OTL decals. These coils are backed by an 18-month warranty.
