The factory coil pack is very known to corrode and fail, along with not support increased horsepower due to "spark plug blowout", which is the coil pack's inability to complete the spark during higher cylinder pressures. The factory coil works fine until you start to add more mods. If anything, this is a nice looking/working replacement. When the coil pack was installed on our car, we were able to run a larger spark plug gap, which will result in better drivability and fuel economy.
