Description

The Pertronix MR-LS1 is an electronic ignition conversion kit designed for Marelli S103-S422 series 4 and 6-cylinder distributors. This kit operates on a 12-volt negative ground system and utilizes a Hall Effect lobe sensor for reliable triggering.

It provides a 2:1 improvement in current fall time over traditional points, leading to increased coil output. The epoxy-molded module is resistant to dirt, oil, grease, and moisture, ensuring durability and stable timing without adjustment. The system is legal in all 50 states and Canada under C.A.R.B. E.O. #D-57-22.
