ACCEL late-model SuperCoils are now available in additional colors – blue and black. They're the same high-quality high-output coils offered in classic ACCEL yellow for years. In addition to the ever-popular ACCEL yellow, Ford Coyote and 3.5/3.7L applications are now available in black or blue, and Hemi and LS versions are available in black. Like all ACCEL SuperCoils, they feature highly specialized silicone-magnetic steel cores, optimized windings, pinpoint-precise resistance, and engineered turn ratios that help unleash your engine's maximum horsepower potential.
