You have three coil wires and three high tension leads that piggy-back to the next cylinder. So each coil wire is responsible for firing two cylinders.

The coil wires are made of solid copper and virtually never wear out. I don't remember how much they are off-hand, but I'm sure they are over $200 for a set.

The coil wire ends (or boots or connectors) are about $7 to $10 each, depending on where you buy them.

95% of all missing or misfire problems on M104 engines are due to a bad connection on these resistor boots.
