Spiral Core: Spiral core spark plug wires incorporate an alloy—usually consisting of stainless steel, copper, and tin—wrapping the core to suppress EMI/RFI while maintaining low resistance.
What kind of spark plug wires 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.
Is there a difference in spark plug wires?
The major difference is the materials, such as the conductor wire, that make up these replacement wires. These are much more durable than the standard wires that come with your car. The wires are designed with a fiberglass braid that quickly and efficiently sends a spark to your spark plugs.
Do thicker spark plug wires make a difference?
Thicker conductors are required to carry more amps, but spark plugs are fired with very high voltage and low amperage. The thicker wires do have better insulation, usually silicone and that stands up to the heat of the engine compartment and higher voltage from modern ignition systems better than the older wires did.
How do I know if my wires are solid core?
There’s more to a plug wire than the color of its skin. The only way to accurately tell one type of wire from another is to go beneath its skin to reveal its core construction. Basically, there are three main types of ignition wire: solid-core, carbon-suppression, and spiral-wound.
Will new spark plugs and wires improve performance?
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. … Worn or dirty spark plugs require higher voltage to get a strong enough spark to start a vehicle.
What is the difference between 7mm and 8mm spark plug wires?
8mm spark plug wires are a heavier gage wire than the 7mm type. … The thicker wire has a thicker core. The core is the part of the wire that brings power to the spark plugs. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.
Can spark plug wires add horsepower?
In short, yes, in some situations spark plugs can increase horsepower. The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel.
Will bad spark plug wires throw a code?
Bad spark plugs can cause your engine to misfire. The engine’s computer uses sensors to detect these misfires and will create a code that turns on the check engine light.

How many years do spark plug wires last?
The ignition cables on a car are made to last about 60,000 miles before they have to be replaced. In some cases, the wires will need to be replaced due to the rubber boots on the end getting damaged and now allowing for a good connection with the spark plugs.
How do I know if my spark plug wires are bad?
Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency. In addition, the engine light coming on or visible damange to the cables can be signs of a failing wire.
Which is better iridium or platinum spark plug?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Why do spark plug wires have resistance?
The resistance of many wires is measured in ohms per foot. … Lower resistance means more of the ignition coils energy is going towards bridging the gap or the spark plug. That hotter spark can create a more even burn of the fuel/air mixture in the cylinder, and thus, more power output from the engine.
Does spark plug wire brand matter?
4 Answers. There isn’t any performance to be gained from spark plug wires, just better build quality, which gives you not a better spark, but rather maintains an appropriate spark for more miles/years before their performance degrades to the point of needing replacement.
Are spark plug wires too big?
Re: Will bigger Diameter Spark plug wires help gas Mileage
More spark = better mileage. Therefore its not the size of the wire(although I would prefer a 8.5 over a 7 for heat insulation and it might help with some stray spark) its the amount of ohms per foot.
