Do aftermarket spark plug wires make a difference?
How do I choose spark plug wires?
Most manufacturers recommend an 8 or 8.5mm plug wire on most applications. Exceptions would be an all-out race car or a street rod where EMI/RFI suppression is not a concern, but weight and appearance are. In which case, a 5 or 7mm wire might be a better option.
Does it matter what kind of spark plug wires I use?
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.
Do you need specific spark plug wires?
Spark plug wires can't add horsepower (despite what some may claim), but they can adversely affect your vehicle's performance. That's why it's important to select a good quality set of spark plug ignition wires to deliver juice to your spark plugs.Oct 9, 2015
Do aftermarket 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.
What are the symptoms of bad spark plug wires?
- Visible Damage on the Spark Plug Wires. Spark plug wires may start to dry out over time, so look for cracks in the insulation.
- The Engine is Idling Rough.
- Engine Hesitation.
- Engine Misfiring.
How do you test spark plug wires?

How do I know if my ignition cables 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.
When should you replace spark plug wires?
between 60,000 and 100,000 miles
Do spark plug 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.
Can spark plug wires increase horsepower?
New spark plug wires can increase your car's horsepower as well as increase your car's pick performance. It provides more spark to the firing tip of the spark plug and increases the horsepower.Nov 2, 2021
Do upgraded spark plug wires make a difference?
Does upgrading spark plugs make a difference? - Quora. There is a absolutely no difference when upgrading Spark plugs with regards to engine performance. Automobile manufacture claims it increases HP but in reality a worn out spark plug misfires compared to a new one, which explains extra HP.
What do high performance spark plug wires do?
Benefits of Spark Plug Wires Stronger and more durable cables hold the spark until it finds its way to the spark plug to boost the performance of your vehicle. Improve gas mileage. High-quality wires will allow the spark plugs to start faster and keep your engine running more effectively.
What's better 7mm or 8mm spark plug wires?
8mm spark plug wires are a heavier gage wire than the 7mm type. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs. Additionally, the 8mm wires have a thicker outer coating that keeps the core safe from damage.Oct 7, 2013
What does a thicker spark plug wire do?
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.
Does spark plug wire thickness matter?
Does size matter? For overall spark transfer, not necessarily. However, thicker wires, like these Moroso Super Max II 11mm wires, can provide added RFI suppression and insulation.Oct 9, 2015
