The car runs a lot better now, but I have an annoying ticking noise coming from my stereo system. The problem is that you have to use a non resistant spark plug for the wires to work properly. The non-resistant spark plug causes lots of RFI noise. I decided to just keep the wires and put some resitor spark plugs in. From a performance standpoint, the high resistance of these wires literally drains power from your ignition system every time a spark occurs.
Car runs perfectly and the blue wires definitely liven up the engine bay.
Resistance has been measured to be half of the stock wires which is exactly what NGK claims. The NGK wires are 4-6 KOhms. Best run with the NGK was a 15.6 sec. This is from Magnecor's information brochure. The difference between the 8.5 mm and 10 mm Magnecor wires is the thickness of the insulation and the price.
