Harley Davidson manufactures its own copper and platinum spark plugs. They are popular, and many Harley riders prefer them for their originality. However, they don\u2019t make Iridium plugs. So, other companies like NGK, E3, and Champion Spark plugs make them for Harley riders.<\/p>\n\n\n\n

The curious rider often wonders who manufactures Harley Davidson spark plugs. You will find the answer to that in a while. <\/p>\n\n\n\n

\"Screaming
Screaming Eagle Spark Plugs <\/figcaption><\/figure><\/div>\n\n\n

The best and the most expensive spark plug from Harley Davidson is the Screaming Eagle. Their engineering supports the highest RPMs and power delivery. You can get them for $23-$35. <\/p>\n\n\n\n

Other Manufacturers<\/h3>\n\n\n\n

All these are copper and platinum spark plugs. In comparison, the most advanced spark plugs are the Iridium ones. <\/p>\n\n\n\n

And since Harley doesn\u2019t make those, they collaborate with companies that do. Examples include NGK, Denso, and AcDelco.<\/p>\n\n\n\n

They have successfully manufactured iridium spark plugs for Harley Davidson Motorcycles for years.<\/p>\n\n\n\n

Materials And Technology Used In Harley Spark Plugs<\/h2>\n\n\n\n

Harley Davidson uses some of the best materials and technologies in their spark plugs. Nickel alloy and copper core, Gold Palladium, and Platinum are the material choices for Harley\u2019s spark plugs. <\/p>\n\n\n\n

Nickel Alloy And Copper Core<\/h3>\n\n\n\n

The material and technology for standard Harley Davidson spark plugs are nickel alloy and Copper core. <\/p>\n\n\n\n

The central electrode of these spark plugs is made of copper. And as we all know, copper is highly efficient in conducting heat and electricity. However, it also tends to wear out faster. <\/p>\n\n\n\n

Thus the nickel alloy coating. It saves the copper electrode from fast decaying. Therefore, it makes a cheap but efficient spark plug with an average lifespan. <\/p>\n\n\n\n

Gold Palladium<\/h3>\n\n\n\n

These are a more advanced type of spark plugs. The central electrode has a gold-palladium alloy tip. Both gold and palladium are precious metals with excellent durability and conductance. <\/p>\n\n\n\n

A gold palladium spark plug lasts longer than the simple nickel alloy variants. They also save fuel and power since it requires less voltage to ignite. <\/p>\n\n\n\n

Plus, they have resistance to fouling. This means the spark plug\u2019s performance will not easily diminish as it ages.<\/p>\n\n\n\n

Platinum<\/h3>\n\n\n\n

Another precious metal that helps increase the lifespan of spark plugs is Platinum. These spark plugs have a welded platinum tip on the central electrode\u2019s nickel alloy base. <\/p>\n\n\n\n

Due to their sturdiness and high melting point, Platinum spark plugs can far outlast the average copper variants.<\/p>\n\n\n\n

They\u2019re also less prone to fouling and require low voltage to ignite. Harley also makes double platinum spark plugs. <\/p>\n\n\n\n

Here, the center and the ground electrode have a platinum tip. As a result, there is less gap erosion and far better performance.<\/p>\n\n\n\n

Where are Harley Davidson Spark Plugs Made?<\/h2>\n\n\n\n

Harley Davidson has strategically placed its factories all around the globe. There are three major factories where they make their spark plugs. <\/p>\n\n\n\n

In the U.S, these are – York, Pennsylvania, and Milwaukee and Menomonee Falls, Wisconsin. <\/p>\n\n\n\n

Outside the U.S., Harley Davidson makes its spark plugs in their Brazil, Thailand and India factories. But why did they choose to do that? Let\u2019s consider their reasons- <\/p>\n\n\n\n

Reduce Production Costs <\/h3>\n\n\n\n

The price of labor and materials is much lower in many countries outside the U.S. <\/p>\n\n\n\n

Setting up factories in these regions helps Harley-Davidson keep their production costs to a minimum. Plus, this allows them to sell their bikes at affordable rates. <\/p>\n\n\n\n

Avoid High Tariffs <\/h3>\n\n\n\n

International authorities, like the EU, impose high tariffs on motorcycle products made in the U.S. <\/p>\n\n\n\n

One way to avoid these expenses is to produce the parts outside America. This is one of the reasons why Harley Davidson chose to open their Thailand factory in 2018. <\/p>\n\n\n\n

Cut down shipping and import costs <\/h3>\n\n\n\n

Riders all around the world crave a Harley Davidson. But shipping and importing these products across borders requires high charges. <\/p>\n\n\n\n

Harley has cut down that cost by opening factories directly in foreign regions with high demand.<\/p>\n\n\n\n

NGK <\/h3>\n\n\n\n

When it comes to iridium spark plugs, NGK has almost no competitor. Their iridium spark plugs are cheaper than Harley\u2019s advanced screaming eagle. Meanwhile, they deliver a much better ignition experience.<\/p>\n\n\n\n

Denso <\/h3>\n\n\n\n

The company makes spark plugs with a central platinum and ground titanium electrode. <\/p>\n\n\n\n

These incredibly sturdy metals permit better ignition and acceleration. Denso also uses alumina powder as an insulator in its spark plugs. thus preventing overheating and fouling. <\/p>\n\n\n\n

Champion <\/h3>\n\n\n\n

If you want to stick with the good old Copper and Nickel Alloy, Champion spark plugs can be an excellent choice.<\/p>\n\n\n\n

Their copper core electrode and nickel alloy center are of the highest quality. Therefore, last longer than other spark plugs that use the same material and technology. <\/p>\n\n\n\n

E3 <\/h3>\n\n\n\n

E3 is famous for its unique diamond-shaped electrode. This patented technology makes combustion more efficient. <\/p>\n\n\n\n

As a result, your Harley Davidson becomes a lesser threat to the environment due to its reduced carbon emission. <\/p>\n\n\n\n

AC Delco <\/h3>\n\n\n\n

The iridium spark plugs from ACDelco can fit into the majority of Harley Davison engines. <\/p>\n\n\n\n

You will experience better fuel economy and more engine power with AC Delco\u2019s plugs. Also, they have a fairly longer lifespan than the average copper or platinum variants.<\/p>\n\n\n\n

How To Change The Harley Davidson Spark Plug?<\/h2>\n\n\n\n

You can easily change the spark plug of your Harley Davison at home. All you need is the owner\u2019s manual and a few simple tools.<\/p>\n\n\n\n

Step 1: Access The OId Plugs <\/h3>\n\n\n\n

Use the owner\u2019s manual to find your Harley\u2019s spark plugs. You will commonly find them on the left of your vehicle. <\/p>\n\n\n\n

Depending on the model, your bike might have four or two spark plugs. You might have to remove the fuel tank to access the plugs. <\/p>\n\n\n\n

Step 2: Unscrew The Old Plug. <\/h3>\n\n\n\n

Pull the old plug at its boot. Twist slightly to loosen it. Now use a spark plug socket and ratchet to unscrew it from the cylinder. <\/p>\n\n\n\n

Step 3: Check the Gap <\/h3>\n\n\n\n

Before installing the new plug, check its gap. This is the distance between the center and the ground electrode. <\/p>\n\n\n\n

Ensure that the gap matches your Harley\u2019s engine specifications. There are gapping tools you can use to measure and adjust the gap. <\/p>\n\n\n\n

Step 4: Insert New Spark Plug <\/h3>\n\n\n\n

Insert the new plug and tighten it gently with your hand. Once it\u2019s snugly fit, use a torque wrench to tighten it according to your engine\u2019s torque requirement. <\/p>\n\n\n\n

Finally, push the spark plug wire to reattach. You should hear a click as the wire attaches. <\/p>\n\n\n\n

Lastly, re-install the parts you had removed to access the spark plugs.\u00a0<\/p>\n\n\n\n
