Where do spark plug wires connect to?
Each end of a spark plug wire has a metal terminal that clips onto the spark plug and distributor, coil, or magneto.
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.
Are all spark plug wires the same?
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.
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.
What type of spark plug wires are best?
Spiral wound wires are a mainstay on any high-performance ignition system. Accel’s 300+ 8.8mm wires feature a carbon/graphite core that virtually eliminates RFI noise while providing maximum conductivity for ultimate performance in any race or street application.
Are Taylor spark plug wires any good?
I have used Taylor plug wires for years and you can not go wrong with the reliability and durability of Taylor wires. Definitely recommend!
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.
Do thicker spark plug wires make a difference?
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.
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.
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.
Will spark plug wires improve performance?
What’s better 7mm or 8mm spark plug wires?
8mm spark plug wires are a heavier gage wire than the 7mm type. However, there is more to it than just the difference in the thickness. The thicker wire has a thicker core. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.
Do Iridium spark plugs increase horsepower?
Increase your performance. Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more horsepower.
How do I know if my spark plug 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.
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.
What should I look for in spark plug wires?
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.
Can you use any spark plug wires?
Wires are not interchangeable. Every cylinder works in sync with a particular electrical connection on the distributor cap or ignition coil, depending on your car model.
What happens if you use the wrong spark plug wires?
If you put the wire for, say, spark plug 1 onto the top of spark plug 4, spark plug 4 is now going to fire at the wrong time. If it fires when the intake valve is open, it could set fire to the fuel-and-air mixture that’s waiting in the intake manifold and the throttle body.
