Does the Murnao have spark plug wires? I don't think it does. Isn't there a separate inginition coil for each plug connected directly to the plug more or less?
Coil's right on top of plug with power transistor, so the high voltage side is very short so a very fast edge can be acheived, less radio noise and dedicated coil for each cylinder means lots of recovery time at high rpm.
Nice illustration jaak. For the less technically minded here, no the Murano does not have spark plug wires, since there is no distributor to connect them to!
Yes, it is pretty cool - no distributor! Or at least in the traditional sense. Actually ECU manages all signals. Here how the wiring diagram looks like, for 3 spark plugs........
