Read you other post...some says cam, but if it was its not gonna smooth out after it warms up. I'd def replace wires if they are leaking current, they shouldnt shock you. Personally I like the Motorsport wires for the money..are there better wire out there of course, do they last a zillion miles no, neither do the $100. With high current ignition systems and daily drivers they along with the high dollar ones will need to be replaced. They are a maintainence item like plugs.
