The Jacobs Mileage Master Kit
The Mileage Master Kit is a multiple spark ignition system designed for daily drivers and mild performance applications.
Advanced digital circuitry continually monitors engine RPM and adjusts the spark intensity accordingly. Spark intensity automatically rises when the engine is accelerating or under load, and automatically readjusts spark intensity once the engine is in a “cruise” mode to optimize spark plug life.

The system is capable of operating engines in excess of 7,000 RPM without any drop-off in performance. Mileage Master is fully compatible with Jacobs’ extensive line of timing and nitrous control products which can be connected using factory finished wiring harnesses for unparalleled ease of installation.
