I had some bulk 8mm Taylor Spiro-core wire, and some MSD 90 degree plug ends on hand... So, I made a set of wires for my bike about 2 years ago, and have not had one problem.... I di-electric greased the wires and pushed them in... I reused the original plug wire retainer, and put it on the new wires so I did not need zip ties... The wires fit tight and don't pull out... All in all it cost me $12 to make the wires..
