The MSD Smart Coil Big Wire Kit allows you to run dwell time over 5 milliseconds to gain the most of the Smart Coils. It will allow the coil to produce 50,000 peak voltage and peak energy of 190 millijoules, this means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder to reach the optimal horsepower out of your engine.

It is compatible with Holley EFI and many other aftermarket electronic fuel injection systems and will run on traditional 12 or 16 volt electrical systems found in race applications.

Unique elongated mounting holes accommodate IGN-1A mounting brackets or allow it to bolt in place of an LS coil with 72mm bolt spacing. The MSD Smart Coil will bolt right onto Holley LS cast aluminum valve covers for a super clean look. Available in red or black.
