I was wondering if anyone has any preference as to which brand of spark plug wires to use/ which ones have worked best in the past and where to get them from. My Trooper runs a little rough in idle. Thanks for the help.

bosch is a good way to go when replacing spark plug wires. go with either 6mm or 8mm depending on how hot a spark plug you run. the hotter the plug, the larger the wires. most older troopers do run slightly rough at idle, rough idle can also be caused by leaking intake manifold gasket or head gasket. typically its a leaky gasket if the idle lopes up and down irradically.
