Dragon Fire Race 10.2mm Spark Plug Wire

These spark plug wires are pretty inexpensive which is what makes them appealing at first. The leads do everything they are supposed to do and probably more.

They are marketed to be compatible with Harley Davidsons which makes them a blind choice for most amateurs and people who are not too fond of shopping for parts online. The wires have a diameter of about 10 mm and have an electrical resistance of 150 ohms per foot. The resistance is on the higher end of those usually found in the market. The wires conducting material is made up of copper-nickel alloy covered using a high-temperature resistant silicone, which can resist temperatures up to 600 degrees. The copper-nickel alloy conduction wires add to the overall durability of the product as alloys are less likely to give in to combustion or corrosion as against most naturally forming metals.

The wires come in a pair, one wire of the length 18 inches and the other of 36 inches, both pretty decent in terms of serviceability. The length of the wires sometimes proves to be a little too long but nothing that could inconvenience someone.

  • High power resistance
  • High heat resistance
  • Wires might seem a little too long

  • RFI suppression core
  • High heat resistance
  • Affordable
  • Excessively high power resistance
