Hello

Mr lee is correct.

But the difference beetween a standard coil and the Porsche HKZ coil is that the Porsche unit doesn´t have to charge the load ( capazity ), it is only a transformator with makes it more effective and faster.

Also the breaker point has only a slight charge to bear and doesn´t need a condensor. The only reason to change it is as the unit will wear mechnical but the contacts will not burn away.

Grüsse
