The standard modules are very prone to spiking causing them to blow.

Causes can be poor battery connections, crude ON/OFF switches and connecting Jump Start packs.

Ignitech is a great replacement but at a price, although some people seem to charge almost the same for a secondhand set of standard igniters.
yet it is possible to get a pair of secondhand igniters for less than half the price of a new Ignitech unit making buying a set as spares an option
