GM 4 Pin Dyna-Module – DUI / HEI

Description

Gain a crisper, smoother running engine by replacing the stock ignition module with our Dyna-Mod. The Dyna-Mod enhances coil output through increased electronic dwell. More dwell within the module extends coil saturation time and this allows the coil to produce a more intense and longer duration spark, improving throttle response and low-end power. For best performance, we recommend pairing it with our Street/Strip or Racing DUI coil, yet it is compatible with any HEI style coil. Great for street, racing, off-road and marine applications. Installation is easy as the Dyna-Mod mounts in the stock location of an HEI module with no modifications.

Fits all V8, 6 Cylinder and 4 Cylinder DUI/HEI Distributors.
