Are you looking for more power from your engine, with a nitrous system, blower or turbo? If so, then you're also demanding much more from your ignition! You need more spark energy to light that air/fuel mixture at much higher cylinder pressures. ACCEL SuperCoils deliver up to 15% more spark energy than your stock coils, ensuring that you'll take advantage of your recent upgrades. In addition to added performance, you'll enjoy the same durability that powers ARCA Racing Series Ilmore engines through extreme racing conditions. Now, ACCEL SuperCoils are available for more applications than ever since we've added import applications to our legendary American muscle tradition.
