What spark plug cables do I need?
What spark plug cables do I need?
Plug wires are most often rated by their diameter. The most common are 7mm and 8mm thicknesses, but what’s more important is the conductor. The best choice is the spiro-wrap style Taylor wires that reduce resistance, minimize RFI noise, and offer the best performance.
What kind of spark plugs do you need?
Some modern vehicles have distributorless ignition systems, which have the spark plug wires connecting each coil pack directly to one or more spark plugs, whereas others are of a coil-on-plug design that removes the need for wires entirely (but that’s another story).
Do you need to replace the spark plug wire?
You’re likely aware that in order to keep your vehicle running in great shape, you’ll need to replace the spark plugs from time to time, but what about the spark plug wires?
What kind of spark plug wire is JEGS?
The JEGS Red Hot Pow’r Wires are considered performance plug wires at economical prices and feature a spiral core design that begins with a strand of Kevlar wrapped 32 times per inch with a fiberglass strand coated in a stainless alloy and then conductive latex.
What are the symptoms of bad spark plug wires?
This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) and electrical stresses. Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency.
When do you need a spark plug wire set?
Signs that you may need spark plugs and wires include a Check Engine light, engine misfires, erratic idling, and increased emissions. New spark plugs and wires can also improve your fuel economy. O’Reilly Auto Parts carries ignition wire sets, spark plugs, and other ignition parts for most cars, trucks, and SUVs.
Why are spark plug wires rated in resistance?
Resistance: Rated in ohms-per-foot, resistance is the ignition wire’s tendency to resist the flow of the electric current. Wires with higher ohms-per-foot ratings will allow less current to flow from the spark source to the plugs. This can affect engine performance and fuel economy in a negative way.
How many ohms does a spark plug wire have?
The resistance of many wires is measured in ohms per foot. A wire with high resistance can be in the 5000 ohms per foot range for especially high-output ignition systems, whereas a low resistance performance wire could easily get double digit ohms per foot.
