Iridium Spark Plugs?

MA70-3.0GT · 05-17-2013, 09:59 AM

The heat in the plug wires is most likely just heat soak from the engine fella. There's about 50,000 volts going through them but barely any amps so I'd have to believe they're not heating from the load

AFAIK the size is just insulation thickness as opposed to the conductor being any thicker too (someone'll correct me if I'm wrong of course)

Some wires do have thicker conductors. Most of Taylor's wires have a thicker core than some of the more common retail wires.... but you have to build them custom if you want them for the 7M. One thing to remember about ignition wires is that the hotter they get the higher the resistance of the wire. The thicker insulation helps a LITTLE here but it's not enough to justify switching over. If the wires are crap then replace them, if not then don't worry about going all out and buying the top of the line in the racing world.
