D.U.I. Dyna-Mod Module - 4 Pin

High Performance 4-Pin Dyna-Module - All V8, 6 Cylinder and 4 Cylinder engines utilizing our DUI Distributor or GM HEI Distributor - Non-Computer Controlled

For a crisper, smoother running engine, replace your stock HEI module with the Dyna-Mod. The Dyna-Mod has more "electronic dwell" in it to provide more coil saturation time. The additional saturation time allows the coil to produce a more intense spark. Our Street/Strip and Racing D. U. I. Distributors require our 4-pin Dyna-Mod.
