Dyno-Tested Results Across Power Levels
These coils have been tested extensively across a wide range of builds—from OEM configurations to high-horsepower race setups. Across the board, users have seen improvements in throttle response, idle stability, and overall engine performance. Whether you're on the street or track, these coils deliver consistent and reliable results.

Increased Output and Enhanced Combustion
Expect over a 10% gain in power output compared to OEM ignition coils. The stronger spark improves ignition reliability, supports larger plug gaps under boost, and helps prevent spark blowout. These enhancements translate into a smoother powerband and better combustion efficiency, making them a valuable upgrade for any enthusiast.

Hassle-Free Installation with Flexible Fitment
Installation is quick and easy thanks to the true plug-and-play design for all EJ20 and EJ25 turbocharged applications. For USDM EJ20 models using black coil packs, compatibility is achievable by swapping coil boots and tuning for appropriate dwell settings, if needed.

Tuning-Ready, But Not Required
Although tuning isn’t necessary, professional tuners can take full advantage of the coils’ improved timing control at higher RPMs. This added precision enables better tuning flexibility, helping unlock greater horsepower and fine-tuned drivability without the need for additional modifications.
