Description
The MSD 6AL-2 Programmable Ignition Box gives you precise control over spark timing and energy—critical for extracting maximum horsepower from your engine while maintaining reliability across a wide RPM range. Whether you’re running a naturally aspirated build, forced induction setup, or nitrous system, this capacitive discharge unit delivers the spark intensity and programmability needed to optimize ignition performance for your specific application. PC-based tuning via MSD’s Pro-Data+ software means you can dial in rev limiters, timing curves, and nitrous step-retard without leaving your workshop.
