The center core of OEM-type spark plug wires is made of a carbon fiber that helps minimize radio frequency interference (RFI). If you’ve got a vintage hot rod or race car with a carburetor and old-school ignition setup (magneto or points-style), you’d benefit from the ultra-low resistance of solid core wires. Types Of Spark Plug Wires. Others are designed to suppress EMI. On top of that, the wires must often deal with larger amounts of voltage from modern ignitions and aftermarket ignition coils. This reduced resistance allows the engine to start easily and even produce a smoother idle than an OEM-replacement wire can. This field can interfere with sensitive electronic devices and create noise that can be heard through the radio and even affect sensors. There are also a variety of color options and plug boot configurations (straight, 45-degree, 90-degree, etc.) The metal in a spark plug serves a single basic purpose: to channel the electric energy from the plug wire through the spark plug so that it can be forced to the engine block in the form of a spark. Spark plug wires are commonly direct-fit to work on a specific application. $52.53 $ 52. FREE Shipping. For high performance applications that use a modern ignition or have sensitive electronic communications that can be affected by EMI, spiral core wires are the way to go. For that reason, solid core wires have lower resistance than other wires to get maximum energy to the plugs. MSD 8750 Distributor. While almost all spark plugs feature a copper core, many people refer to the common spark plug as a “copper” spark plug. So which spark plug wire style is right for your vehicle? Copper is a great electrical conductor with low resistance.. R1813 New Universal Spark Plug Wire Set (4 Cyl.) However, carbon fibers are not great conductors of electricity and develop a strong resistance to current flow in the plug wire’s ability to carry the electrical current. Double fine wire electrode (DFE) spark plugs apply a fine wire pin to the ground electrode in addition to a fine wire center electrode. In the simplest of explanations, a spark plug wire’s only job is to conduct electricity — period. Let me know if you have any questions. Copper spark plugs die out way faster than the other two types. It offers excellent RFI suppression but also creates more resistance than other styles. Solid Copper Wire Core.
