Best Spark Plug Wires For Harley Davidson Buyer’s Guide

Key Features Of The Best Spark Plug Wires For Harley Davidson

The ignition wires’ important characteristics are shown below. Consider these factors to choose the best spark plug wires for Harley Davidson.

Stainless Terminals

The ignition wires heavily rely on the terminals. To provide long-lasting function, they should be corrosion-resistant. These connections attach The wire to the distributor and the spark plug.

They should produce a powerful bite on the spark plug to prevent unplugging during vibration. The spark plugs may only get high power if the connections are tightly fastened. If they rust, they lose some of their effectiveness. Decide on a corrosion-free termination. ignition wires

High Resistive

It would help if you got spark plug wires with high resistance. The resistance of the ignition wires is typically high, but certain cables have low resistance. High-resistance wires have the advantage of reducing frequency interference.

If you use high-resistance wires, the electromagnetic waves produced surrounding the ignition wires won’t interfere with your car’s sensors, computers, or radio. The spark plug wire resistance varies from 8,000 to 12,000 ohms per foot. Choosing a spark plug wire with a high resistance value is key.

Copper Conductor

Copper should be used as the conducting material in the ignition wires. It is quite conductive. A high conductive substance is preferable for transmitting because the spark plug wires transmit approximately 10,000-volt power from the distributor to the spark plugs. The spark plug receives the maximum voltage at the appropriate time.

Compatibility

Check if the spark plug wire type you intend to purchase is compatible with your car. As you can see from the list above, certain things are suitable for Dyna Harleys, while many others are compatible with Softail Harleys.

The distributed resistance wire is the ignition type that works with most American vehicles. Inductance wires are the best option if you drive a Japanese car. Additionally, the set resistor wires are effective for European automobiles. So make sure to check the Fitment when you go to buy ignition wires.

Number Of Spark Plugs

You’ll also need to purchase a different wire for each plug because different automobiles have varying numbers of spark plugs. To fit on each spark plug, some wires split into many wires. If your car has three spark plugs, you’ll need three different wires or one wire with three other ends.

What suits you best is separate wires for each plug or a terminal arrangement. Select such wires to fit them onto the plugs since spark plug wires typically come in sets. Buy a different wire for each spark plug if you’ve previously used separate wires for

Benefits Of Spark Plug Wires

Increases Engine Performance

New spark plug wires enhance the performance of your car’s engine. Due to heat energy and high temperatures, the old wires you’ve been using for years have worn out. They no longer supply the spark plugs with enough spark.

Your engine won’t start, unfortunately. And the automobile gradually gains speed. Installing new ignition wires provides and maintains the maximum spark to the plug, improving engine performance.

Improves Gas Mileage

You’ll need to make additional gas station trips if you’re operating your vehicle with a damaged spark plug wire. Old ignition wires cause less gas mileage, which increases your fuel costs. On the other hand, the engine starts more quickly and runs more efficiently when high-quality ignition wires are used.

According to studies, quality spark plug wires enhance gas mileage by 4%. Additionally, low-spark spark plugs diminish fuel economy by 30%. This is the reason why spark plug wires not only boost the efficiency of your engine but also its performance.

Save Money

Utilizing ignition wires of higher grade helps you save money. The high voltage transfer won’t cause them to deteriorate—the low expense due to less new spark plug wire installation.

Spark plugs will become destroyed after prolonged low voltage if you don’t replace your spark plug wires. You’ll pay more for them than for new wires alone. The biggest advantage of replacing spark plug wires is cost savings.

Reduce Radio Frequency Interference (RFI)

Your car’s ignition system has an impact on radio frequency. There will be a lot of noise and fading if you listen to the radio while driving. The ignition system is what is causing the radio frequency interference.

However, interference is reduced when utilizing high-quality spark plug wires. Spark plug wires made of carbon exhibit great resistance to the adjacent frequency. Additionally, they lessen interference with other sensors and computer systems in your automobile, particularly when you are on the phone. Another significant advantage of new ignition wires is a decrease in RFI.

Types Of Spark Plug Wires

The four varieties of spark plug wires are listed below. They benefit your car and the ignition system in several ways. Reading about these different wire kinds can make choosing the spark plug wires for Harley Davidson that best suit your needs easier.

Distributed Resistance Wires

These wires have excellent resistance properties. Carbon and fiberglass are used in their construction, which provides extremely high resistance to radio frequency interference. Most automobiles have dispersed resistance spark plug wires for energy transfer as a result of this characteristic.

The fact that dispersed resistance wires cut down on RFI, which in turn helps cut down on radio noise, is one of the reasons why most cars have them installed. So radio sound without fading. Additionally, you ought to choose this kind of wiring for your Harley because the ignition mechanism of many American autos uses these wires.

Magnetic Resistance Wires / Inductance Wires

Inductance wires are used in the majority of Japanese automobiles to carry energy from the distributor to the spark plugs. Such wires feature a spiral core made of copper, nickel, or possibly a combination of the two metals. It generates an electromagnet that ensures maximum current flow while preventing RFI.

Fixed Resistor Wires

The fixed resistor wires, primarily used in vehicles from Europe, are another kind of spark plug wire. Either steel or copper is used to make these wires. Steel wires are inferior to copper wires in this area. Since they are more conductive than steel, energy is transferred quickly. The fixed resistor wires are so-called fixed resistor wires because they have resistors at the spark plug boots.

How Often Should You Change Spark Plugs On A Harley Davidson?

When riding a motorcycle, one of the things you hardly ever consider is the spark plug. They don’t show up on your typical checklist, including items like tires and turn signals.

Spark plugs must occasionally be replaced for the motorcycle to keep providing you with the services you require, so you shouldn’t fully disregard them.  For the bike’s best performance, spark plugs must be installed and maintained properly. The big question is how frequently you change the spark plug in your car.

Spark plugs need to be changed in modern motorcycles every 15,000 to 16,000 miles of riding. However, just consider checking and changing the spark plug if your bike is stuttering, running rough, or even losing power.

Ask the seller when the spark plugs were last changed if you are purchasing a used motorcycle. Consider replacing them immediately if the previous owner cannot recall or is uncertain to protect your safety.

It is important to note that you must verify the spark plug’s compatibility before replacing it. Manufacture that your motorcycle’s model, manufacture, and engine type are all compatible with the spark plug you’re using.

Consider how well it works with your gasoline. The performance of the spark plug and its enhancement of engine performance in terms of power efficiency, ignition time, and fuel economy are additional factors to take into account.

Do Iridium Spark Plugs Increase Performance?

Iridium spark plugs improve performance by creating enough sparks to start the ignition system’s fuel-air combination. Using a new spark plug that has been properly gapped prevents skipped firing or early combustion, both of which can harm the engine.

Despite not being one of the best electrical conductors, iridium can function as a spark plug. The copper version is inferior to iridium, which has a service life of about 60,000 kilometers.

Which Is A Better Spark Plug Material, Iridium Or Platinum?

There are several factors to consider when deciding whether platinum or iridium makes a superior spark plug. Durability, effectiveness, and reliability are a few of these elements. Iridium is the hardest metal, whereas platinum may be harder than copper. So an iridium spark plug can perform better than a platinum spark plug.

Iridium once more outperforms platinum in terms of performance. Iridium is still more resilient and has a longer lifespan than platinum.  Iridium’s only drawback is that it is expensive and hard to get in the market, but if you do, you can count on using it for a very long period without needing to replace it. Iridium is, therefore, far superior to platinum.
