Upgrading your ignition in your C10, but want to keep your stock distributor? The Ignitor II (91181LS) takes the proven performance of the original Ignitor, wrapping up even more features. The Ignitor II units sense the coil current level, and use a powerful micro controller to adjust the dwell. 

Features and Benefits:

- Adaptive dwell maintains peak energy
- 4x more ignition energy across RPM range than stock
- Adaptive spark timing compensates for electronic delay
- Synchronized peak current and spark timing reduces heat build-up
- Senses startup and develops more energy for quicker, easier starting
- Built-in reverse polarity and over-current protection prevents damage
- Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-22)
