Pertronix 91181 Ignitor II GM Eight-Cylinder Conversion

The Ignitor II adjusts dwell in response to coil current. It converts selected GM eight-cylinder applications to electronic operation.

Product details

Ignitor II senses coil current and uses a microcontroller to vary dwell, maintaining peak energy throughout the RPM range. It develops up to four times the energy of standard ignition systems between 3000 and 5000 RPM. Using a Flame-Thrower II 0.6-ohm, 45000-volt coil improves high-RPM performance. For selected GM eight-cylinder applications designated 57–74; confirm the complete years.

Features

• 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
• Compensate For Inherent Electronic Delay By Adjusting The Spark Timing Throughout The Entire RPM Range
• Synchronized Peak Current And Spark Timing Reduces Heat Build-Up. Compatible With Most Capacitive Discharge Systems
• 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
• Limited 30 Month Warranty
