As @tlhIngan said, the benefit of good wires isn’t so much the quality of the spark when they are new, but the longevity of the wires. Spark plug wires don’t lead an easy life, they are exposed to high temperatures and high voltages and a lot of strain and bending during plug changes and other work around the wires.

What is the best spark plug wire core material?
The majority of spark plugs feature a copper-core center electrode. Copper is an excellent conductor of electricity – better than any other type of material used in spark plugs – and also transfers heat faster.
Should I use OEM spark plug wires?
Generally you will want to stick to an OEM-type spark plug wire, unless you’re confident a high-performance product won’t affect your vehicle negatively. Another key important factor is to always purchase new spark plug wires, as you’ll never know how used second-hand parts are.
Are NGK wires worth it?
For anyone who needs a good-quality set of spark plug wires, consider the NGK Spark Plug Wire Set. They provide a powerful spark to the plugs for an instant and powerful start. For those who want to save a bit of cash and still get a top-rated wiring kit, check out the Denso Spark Plug Wire Set.
Which is better 7mm or 8mm spark plug wires?
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. These wires also have a thicker layer of suppression material.
Is higher ohms better for spark plug wires?
The higher voltage of a coil on plug or distributor system can create enough voltage that a slightly higher resistance wire will not greatly affect spark strength, but the relatively lower output of a magneto means using a lower resistance wire is more important to ensure a hot spark from the spark plug.
Does it matter what spark plug wires you 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.
Can spark plug wires increase horsepower?
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.
Is ruthenium better than iridium?
Ruthenium has a higher melting point than Iridium, so it may be a better choice for applications that require a high degree of heat resistance. Overall, the key difference between Ruthenium and Iridium is their price. If affordability is a key concern, Ruthenium may be the better option.
Are platinum spark plugs better than copper?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
Are iridium plugs worth it?
Iridium spark plugs are the most expensive spark plug model on the market, but in many cases they are worth the investment, as the premium price also comes with high performance and reliability.
How long are spark plug wires good for?
A quality set of spark plug wires can generally last around 60,000 to 70,000 miles. Again, it is a good idea to replace these parts prior to a failure, like a misfire.
When should you replace spark plug wires?
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).
Can I change spark plugs without changing wires?
It is not necessary to change the wires but it’s a good idea. Here’s the reason. If your spark plugs have been in the engine too long the component at the end of the plug get’s oxidized over time from having such high voltage run across it to jump a gap and create a spark.
Where are Denso spark plugs made?
All DENSO Spark Plugs are manufactured in Japan, Indonesia, China and USA.
Do HT Leads improve performance?
Performance HT Leads are Worth it
As soon as the flow is interrupted, the magnetic field collapses, creating or inducing a higher voltage in the secondary set. This is the current that then gets directed to the spark plugs.
Are NGK spark plugs good?
Consistently high quality, a comprehensive applications catalog and time-proven performance make NGK an excellent choice for standard electrode and noble metal wire tipped spark plugs.
