I can't say that the OEM wires specifically fixed the problem I was having. It was more of a combination of things. I even replace my ignition coil then. It's been awhile ago now and I don't have the problem anymore.

NGK-Rs are plugs. All of their wires are "blue." You can try the new NGK Power Cables they have out. They may be comparable to the Mangacors. However, they are also double the price of the regular NGK wires.
