No 6-packs but I do carry an extra, actually 2 of them that Mallory supplied to me at no charge seeing that when I bought my ignition they had a run of defective modules & I ended up with 4 of them before Mallory figured out that a supplier had sent them diodes that were not up to spec. Needless to say there were several trips on the water that didn't end very happily. Once Mallory found the problem & sent me the updated modules there has not been a hint of an ignition problem.
