DYNATEK Non-Programmable Ignition System - Yamaha DFS7-21

Stock ignition systems limit your engine's potential with weak spark energy and fixed timing curves that can't adapt to your bike's demands. The DYNATEK DFS7-21 replaces your factory module with 800% more spark energy and four programmable advance curves, giving you precise control over ignition timing for superior throttle response and easier cold starts. Whether you're chasing lap times or optimizing a modified engine, this plug-in replacement puts performance tuning in your hands without the need for expensive standalone systems.
