MSD Timing Twister retard controllers are the easiest way to retard the ignition timing on your engine. These controllers simply plug directly inline to the factory cam and crank sensors, allowing you to easily dial-in an amount of retard. MSD Timing Twister retard controllers come extremely handy with nitrous or forced induction systems--allowing you to set a boost/retard rate (Requires MAP sensor).
