Marelli S155/S156 Series 4 Cylinder Ignitor® II Electronic Ignition Conversion - 12 Volt Negative Ground - PerTronix 9MR-142A

Features & Benefits 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. Compensates for inherent electronic delay by adjusting the spark timing throughout the entire RPM range. Synchronized peak current and spark timing reduces heat build-up. Senses startup and develops more energy for quicker, easier starting. Pair with a Flame Thrower Canister Coil for optimal performance Legal in all 50 states and Canada (C.A.R.B. E.O. #D-57-22) The Ignitor II provides increased starting voltage with adaptive dwell control. Ignitor Module Kits are extremely easy to install and fit into your original distributor to maintain your stock look. No additional ignition box is required keeping a clean look under the hood. Ignitors are available for most distributors that came with mechanical breaker points and will cover AUTOMOTIVE, MARINE, INDUSTRIAL and AGRICULTURE applications Ignitor Electronic Ignition Conversion Kits have proven themselves in applications ranging from race cars to tractors. It is the number one Electronic Ignition Conversion Kit to replace original mechanical points. A Pertronix Points Conversion kit allows you to run a stock distributor while improving the reliability and performance of your ignition system. The Pertronix Ignitor kits simply bolt to the distributor in place of the points assembly and provides a much more accurate trigger signal. This improves the timing accuracy and prevents ‘points bounce’ at higher rpm. The electronic technology also improves the dwell control to improve the spark output of the coil resulting in a hotter spark at the spark plug. With this dependable, self-contained, maintenance free electronic ignition system you'll never replace your points again.
