Spark plug wires and boots

Did some searching but couldn't find any info on this......

Have any of you guys replaced your original spark plug wires/boots?  On the ZN1300 the wires/boots are a molded set (IIRC the KZ1300 has removable plug caps ??)   In any case, the resistance of the ZN wires is specified at about 3k ohms for the inner cylinder wires to about 6k ohms for the outer cylinder wires - appears to be approximately related to plug wire length.  If I could find some 8mm wire (the OEM wires seem to be about 7.6mm) that was about 5k ohms per foot, and if I could find zero resistance caps, I'd be set but no luck on either hand.  What have you guys done?  I suspect the ignition system components resistance on the ZN1300 may have been fine-tuned in order to reduce RF impact on the entertainment systems as much as possible.
