These new coils come from the US, best quality. Avoid cheap new coils that only last a year if that. We fit these on GS and GSA. If your car has a Ballast resistor we bypass them by taking the 12v feed off the ballast and fit it onto the positive side of the coil. These coils are 3 ohm and we recommend adjust the plug gap from 25 thou to 40 thou.
