MaxSpark IGN1A Ignition Kit - 90-05 Mazda Miata

The MaxSpark Plug & Play IGN1A Ignition Kit is the most powerful, complete, and bolt-on ignition upgrade available for your Mazda Miata. Whether you’re running a naturally aspirated engine, high-compression build, or a turbo/supercharged setup, this system provides the cleanest, most powerful spark possible—eliminating misfire, improving idle, throttle response, and unlocking more power.

Unlike DIY COP conversions with lower-output coils, the MaxSpark system delivers over 100 mJ of spark energy per event—nearly double the leading competitors.
