Doesn't look like the cylindrical unit in my car.  I guess it looks like the transformer component of it, but as I suspect the insulation is breaking down and affecting starting on damp mornings, then it is not what I am after.  Or is the picture wrong. 

In short I am after a Bosch Ignition Coil pack for a '91 8v Mk2 Gti with a PB engine!!

Any help appreciated.
