Do performance ignition wires make a difference?
They’re stronger, that’s about all. If you’re racing, or driving a high-performance vehicle, buy the high performance ones for the simple fact they can handle higher temperatures.
Where are the ignition wires located?
The wires are typically located next to the valve covers in the cylinder head. On one end, each wire will be attached to a spark plug and on the other end, to a distributor or ignition coils. Understand why spark plug wires wear out.
What are the ignition wires?
Spark plug wires (also referred to as ignition wiring) transfer the spark from the distributor or ignition coil to the plugs. The subsequent spark ignites the air-fuel mixture in the combustion chamber of your engine.
How do I know if my ignition wire is bad?
Attach the test light to a good engine ground. With the engine running, move the test light along the length of each spark plug wire. If a spark jumps from a plug wire to the test light at any point, this is an indication that the insulation has broken down, and the spark plug wire should be replaced.
Are bigger spark plug wires better?
That thicker wire core provides a lower operating resistance, allowing more spark energy at the spark plug. This thicker core, once wrapped in the insulating material and outer jacket, is what dictates the larger overall spark plug wire diameter.
What color wire is ignition?
Red, Black, White-Red and White Black are the new colors of the key ignition switch wiring.
What are ignition wires made of?
Spark plug wires have an outer insulation several times thicker than the conductor, made of a very flexible and heat-resistant material such as silicone or EPDM rubber.
When should ignition wires be replaced?
between 60,000 and 100,000 miles
That’s why it pays to replace your spark plug wires before they wear out. We recommend changing them during spark plug changes (whenever your owner’s manual recommends, usually between 60,000 and 100,000 miles).
