Crane HI-6S Multi-Spark Ignition

Product images may differ from actual product appearance.

This new box from Crane is a plug-n-go installation for 4,6,8 cylinder engines that use a distributor. It provides up to 70% more spark-gap energy than a stock ignition! It has a maximum output up to 8,000 RPM for up to 9.5:1 compression ratio. It is sealed with a soft urethane encapsulation seals against moisture, dirt, dust, vibration, and heat. The box includes a built in, adjustable rev limiter in 100 RPM increments from 3100-9900 RPM. It is inductive ignition, so it will give a long duration spark. For use on computer-controlled cars/trucks without vacuum advance. Triggers from stock electronic ignition. Not compatible with distributorless ignitions.
