The ION sensor is not in the wires but in the ECM. If the wires have different resistance than stock the ION sensor in the ECM will not sense detonation/pre-ignition and in turn fail to retard the spark when pre-ignition occurs. That guy's email answer sounds like "try it, you'll like it" but if he knew his stuff I'd think he would tell you the ohms of their wires and compare that to the stock wire. Do some more research.

 

I bought the Magnum 8mm red wires for my 2007 NT. I had no idea about the ION sensor, and they companies selling these wires are not going to tell you. I took mine off when the dealerexplained it to me. I wonder what the extent of the damage would be if you left the wires on, Fowled plugs?? I had mine on for about 500 miles and did not notice any differance in performance.

 

Accel makes yellow spark wires that causeno prob. J&P has them

they are called custom fit sparkwire set for 1999-2008 model Accel

If your bike is a dresser here is the part number### 383-281 yellow. Price 19.99

I hope this helps you.

There are a lot of variables involved so your answer could be anywhere from "not much" to holes or cracksin pistons & engine failure though I have not heard of this ever happening due to the wrong plug wires. Most likely you would have been hearing the pinging while under acceleration.

Basically the ion sensor will retard spark if it senses already burned fuel when it provides the spark. It's a very clever system if you ask me. There is a different resistance in the spark whenit travels through an unburned mixture compared to when it travels through burning or already burned mixture (which is what happens when the fuel selfignites "pre spark"like when pinging occurs). It takes a couple of revolutions for the ecm to sense the abnormal resistance and for it to react.If the bike is prone to pinging it will still ping just not as much. If youkeep a steady throttle setting the spark will be retarded by the ecm enough to stop the pre-ignition(within limits) until the conditions change. Conditions such asintake manifoldvacuum(load)/throttle setting/rpm.

Doc, did I get that right?

If by using those wires you were hurting your engine you might have heard the pinging under acceleration. It would be more likely to happen with lower octane fuel. My advice, don't worry be happy. I'd bet you have done no harm,you already fixed the cause.
