so che in francese si chiama *bloc de bobinage* ma non ho trovato la traduzione diretta in italiano :-(

"1. What is a coil pack?
Thanks for asking. The coil pack replaces distributor caps on "new and improved" ignition system. Instead
of having a rotor and distributor cap "distribute" the ignition spark to individual cylinders at the right time
and order, the spark is controlled electronically though the electronic ignition system. The coil pack is
where the actual electrical current (spark) is sent to each spark plug via the wires.

2. The pack is generally comprised of a metal base with a plastic top (insulates the metallic parts so the
current is not immediately grounded).
3. The coil pack is located on the right side of the engine (look from the front) under the plastic manifold
covers. Just follow the pretty spark plug wires to the end and they attach to the coil pack.
4. It seems that the VR6 coil packs (at least pre 98's) just suck. I am not sure if the plastic is not
formulated properly, if the molding is not performed properly or if the design does not distribute stress/heat
well but by listening to the problems people on this list have had, the coil pack is NOT a quality part.
Either that or it is designed obsolescence, keeping the dealer stocked with easy, $500 repairs every
30,000 miles."
