Had enough of the unnecessary and untimely failures from other problematic Miserable Spark Devices?  Well, here is the solution! This unique ignition and wiring system provides maximum performance of your engine, with quick and easy swapping of various and different ignition modules and to other vehicles also equipped with the Cobra Valley HotSwap ignition system.

Crane® Hi-6 digital ignition has an onboard digital dial adjust rev limiter and built in diagnostic troubleshooting indicator. The high powered Crane® Nascar coil releases even more additional power from the Crane® Fireball box! The HotSwap Crane HI-6 box and Nascar E-coil combo kit comes with the HotSwap quick disconnect plugs.
Hardwire kit comes with the same above box and coil components, but without the quick disconnect ends where you just hardwire the ignition in place of your previous one.

Unlike other ignition boxes which have small, fragile and easily bent connector pins, our robust connectors are protected  from damage and being bent even during the unpreventable hurried or careless plug-ins. Our connections are individually hand crimped and each terminal is hand soldered and individually assembled for professional race and street reliability. After all, having to stop in a middle of a race on the Super Speedway is almost as bad as stopping in rush hour traffic!
