PerTronix 91481 Ignitor II Adaptive Dwell Control, Holley 8 Cylinder

Ignitor II systems develop up to 4 times more energy between 3000 and 5000 RPM than standard ignition systems. High RPM performance is improved when used with the Flame-Thrower II super low resistance (0.6 ohms) 45,000 volt coil.

• Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance.
• Develops on average 4 times more available energy between 3000 and 5000 RPM, and 2 times more available plug voltage.
• Peak current level is reached just prior to spark for maximum energy without the heat build-up, increasing coil and module life.
• Adjusts spark timing at higher RPMs to compensate for the inherent electronic delay.
• Senses startup and develops more energy for quicker, easier starting. Built in reverse polarity and over current protection shuts down the system, preventing component damage.
• Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-2).
• Guaranteed for 30 months.
