Best choice for spark plug (ignition) wires?

Question

I own a 2001 Ford Mustang, 3.8L V6. I need to change the spark plug wires and am in the market. I've noticed that the prices can range from $30 to $150, and would like to know if spending more money is actually worth it for the part. I know that going for cheap is probably not a good idea, but should I buy the $80 ones or the $140 ones? At what point would I not notice a difference? Feel free to recommend specific brands. Thanks!

Answer 1

The basic Bosch or Motorcraft plug wires are fine for your application. The el-cheapo wires won't cost you any power, they just won't last as long before you get misfire. Cheap wires may last a year, expensive wires may last 4 or 5 years. If you get a set of cheap wires with a lifetime warranty, you can get another set when they wear out for free. Just save the receipt.

Modified or race applications call for the expensive wires. When ignition output is increased by using a high-po coil, wire dielectric withstand voltage must be increased as well. This prevents the spark energy from arcing over to the engine block. Thats why some performance wires are 8 to 10mm in diameter- for higher voltages produced by high output coil. The actual power supplied to the plugs is controlled by the coil, not the wires. The resistance wire in sparkplug wires is used for EMI/RFI noise suppression. It doesn't affect power handling ability. In fact, MSD boxes state to NOT use with solid-core race wire. The RFI static messes with the MSD's little brain.

There is absolutely no reason to change your spark plug wires, unless they are visibly mis-firing or arc-leaking. Modern engines must meet stringent standards, and the factory wires are JUST FINE!!! Your best bet is to use another set of factory wires. Many European engines use modular wires, where the plug end can be unscrewed and replaced. I am assuming that you have a distributor on whatever car this is. European made Bosch wires are very good. American made Bosch wires are not as good. Use Bosch Fusion spark plugs, or Denso Iridium plugs. These produce the best power and fuel economy. Japanese spark plug wires should last for the lifetime of the vehicle!!

Answer 3

With the electronic ignition of these days the spark plug and wires inductance ( resistance) value is critical. So I recommend that you get the dealer parts. A couple of times I has selected other brands and the engine ran very rough in both occasions.

Answer 4

The best bang for the buck is Magnecor. They are suppression wires, but they use inductance cable rather than carbon ribbon. Buy a set, they'll last the life of the car.

Answer 5

unless you are into racing the $150 wires are a waste of money, just get the ones that come on it from the factory.

Answer 6

Find out what materials the expensive ones are made out of. Then find the cheapest ones made with similar materials. Just make sure whatever you get has a high temperature rating.

Answer 7

I like Accel...... go with a thick MM like 10mm.... dont pay $150.... no wires are worth that much..... MSD are very good wires too.

Answer 8

i say bosch is the best. I run them in my race car. Accel is very good also. Do not know how much you wanting to spend. With bosch or Accel you gonna pay for them though. Remember you get what you pay for.

Answer 9

Motorcraft... does anything else fit better....

I run NGK, on my ricers....

Answer 10

dealer ship, and just go with the oem, cant go wrong.
