  • Davis Unified Ignition (D.U.I.) Dodge Tri-Power Ignition Systems are designed for small block and big block Dodge/Chrysler engines where standard D.U.I. distributors will not fit due to size. The Tri-Power ignition system is equipped with a Dyna-Module (HEI style module) mounted externally to the distributor housing and also includes a high voltage Inferno coil which is mounted externally from the distributor. This Inferno coil allows spark plug gaps to be opened to an incredible .055″. Each Tri-Power distributor is custom tuned on a distributor machine, features a super smooth advance curve to eliminate engine damaging detonation, provides instant throttle response and produces maximum power throughout your entire rpm range. With the combination of the high voltage coil and high dwell module, you will notice quicker starting, smoother idle and better performance up to 7,500 rpms.

  • For small block and big block Dodge/Chrysler engines.
  • High-dwell Dyna-Module.
  • Inferno coil.
  • Custom calibrated.
  • Performance up to 7,500 rpms.

  • Some parts are not legal for use in California or other states with similar laws / regulations
