Founded in the mid 1970s by the late legendary racer and ignition wizard Kelly Davis, Performance Distributors is well known to oval track racers around the country as the manufacturer of the D.U.I.

Performance Distributors' Racing D.U.I. (Davis Unified Ignition) Distributor can almost double the output of a stock H.E.I. Precision built, the ignition system is capable of turning up to 10,000 rpm.
