I changed my ignition wires from those really crappy carbon fiber string resistance wires that came on the car when I bought it (USED) and installed the 10.4MM taylors, the color of the spark at the plugs went from weak blue to a strong bright blue, BTW
HERE is A QUICK IGNITION TEST
you can easily test your spark by simply using insulated gloves and before starting your engine pull an easily accessible plug wire off a spark plug and insert a #2 Phillips screw driver into the end of the wire,then hold the insulated screw driver handle so the shank of the screw driver is about 1/4" from a grounded part of an engine bracket or valve cover while a buddy starts the car, you'll quickly see the ignition spark jump to the grounded area if the ignitions functioning correctly, spark should be bright blue and you should hear a noticeable snappy sound, if its weak, red, yellow and makes darn little noise you need to investigate further, replace the plug wire onto the spark plug and resume testing after shutting off the engine first of course.
A... Voltage .Ohm . meter and timing light will come in HANDY
