Continue reading to get all the answers that you are looking for.

Harley-Davidson spark plugs to improve the engine and performance

A Harley-Davidson spark plug is a motorcycle component that sends electric current from the ignition to the combustion chamber of the engine. It ignites the compressed fuel-air mixture for the perfect combustion engine performance and sound associated with Harley-Davidson bikes.

A good spark plug is built for performance and strength, and it’ll have high-quality metal tips for withstanding constant sparks. The materials will be constructed with compatible coefficients of expansion such that the heat doesn’t cause them to crack or break. A spark plug is a lot more than meets the eye. All bikes, including the ones from Harley-Davidson, will require a suitable spark plug for optimal engine starting and performance.

Who manufactures Harley-Davidson spark plugs?

If you are in the market for new spark plugs, you’ll want to know who manufactures the best Harley-Davidson spark plugs. Here are some of the best spark plugs that you can use for your Harley-Davidson bike – 

1. NGK Iridium IX Spark Plugs

The NGK Iridium IX Spark Plugs are dual cam spark plugs and when they’re used, they give up to 3HP gain. These spark plugs have an electrode 25% smaller than platinum. They are one-quarter size compared to the conventional nickel electrode.

It features an ultra-small diameter of the electrode in the center, which helps reduce the voltage requirement and prolongs the life of the ignition system. Thanks to the metal coating of the housing, the anti-corrosion qualities are improved. If you’re in the market for new spark plugs, this one is recommended as it is one of the best spark plugs for your Harley-Davidson bike.

2. E3 Spark Plugs

The E3 Spark Plugs are efficient and offer smooth acceleration. The E3 Spark Plug is a brand-new ground electrode module that offers efficient combustion fuel for your bike, having more pressure inside the cylinder.

The Diamond electrode will extend this spark into the combustion changer, which brings it closer to the robust air-fuel mixture. The initial ignition wave exits the spark zone at supersonic speed, while the raised edge will provide chimney impact, allowing the same procedure to occur more quickly in the next round. Therefore, an E3 Spark Plug is one of the best spark plugs for Harley-Davidson bikes.

3. Screamin’ Eagle Performance Spark Plug

Screamin’ Eagle Performance spark plug is double platinum coated for resisting superior erosion and extending the service life. It comes with a “V” trimmed ground electrode, and it reduces the chance of covering the flame side. It’ll promote the spread of flames.

The fine wire in the center of the electrode will facilitate the start and the ability to ignite. It is designed with original equipment that suppresses noise while inhibiting electrical interference with other devices such as radios. Moreover, it’ll come with Ribbed Core technology, which is highly resistant to fouling. It’ll perform excellently in racing applications, which will require a lot of air/fuel.

The design of this spark plug is unique, and it is sold in a pair. It is appropriate for modified engines, including high-performance carburetors, high-flow air cleaners, camshafts, exhaust systems, and ignition systems along with stock compression ratios.

4. Harley-Davidson Original Equipment Spark Plug

Harley-Davidson Original Equipment Spark Plugs are sold separately, and these spark plugs are entitled to a 1-year warranty. These are incredibly popular spark plugs and come with a long life.

5. Gold Spark Plugs

The Gold Spark Plugs are often associated with a unique thread and housing liner, ensuring there is a quick and easy means of removing the aluminum heads while also resisting corrosion. It comes with gold-palladium, which will prolong its life and strengthen it to resist corrosion.

The tapered tip will offer good exposure to the spark from the air-fuel mixture, while also allowing smooth flow through the gap zone for maximum ignition. The small diameter in the center of the electrode wire and the top of the insulator will improve resistance to fouling. The copper core ground electrode will run cooler for lasting longer. It’ll also have threads that don’t cling to the coat.

6. Champion Sparking Plug RA8HC

Champion Motors might be the leader in the development and innovation of spark plugs. They’re the original company that created the very first commercial spark plug almost a century ago. It’s a copper core spark plug, and it makes use of nickel alloy electrodes and thermal bonding for creating a wider insulating base with a long insulating tip. This spark plug will come with a heat rating of 8 while having a standard 12mm thread with a 5K Ohm resistance.

7. DENSO Spark Plugs 3297 Iridium

The DENSO Spark Plugs 3297 Iridium is the first one to use iridium in spark plugs and has now become one of the most popular components for contemporary high-tech engines.

The company makes use of the 360-degree laser welding process for creating a high-performance spark plug, which is extremely durable. With state-of-the-art technology, this device has been designed to offer unmatched functionality, fit, and reliability.

How often do you need to change the spark plugs on your Harley-Davidson bike

Spark plugs are among the components that bikers rarely think about when riding their bike. They don’t appear on the standard checklist like turn signals and tires, among others. However, you shouldn’t ignore the spark plugs completely, as they need to be replaced at some points for the motorcycles to continue providing the services that you require properly.

Proper installation and maintenance of spark plugs will be key to getting the best performance from your Harley-Davidson bike. So, how often should you change your bike’s spark plugs? On modern Harley-Davidson bikes, the spark plugs have to be replaced every 15,000 to 16,000 miles of riding your bike. However, if your motorcycle sputters, runs rough, or loses power, you should think about inspecting and replacing the spark plugs.

If you’re purchasing a second-hand Harley-Davidson bike, you need to ask the seller about the last time the spark plugs were changed. If the previous owner is unsure or doesn’t remember, you should replace them immediately to ensure their safety.

It’ll be worth noting that when replacing the spark plugs, you’ll have to see their compatibility. Make sure that the spark plugs are compatible with the build and model of your bike and also the type of engine. Moreover, you should consider its compatibility with the fuel. Another consideration would be the functionality of the spark plug and its improvement in engine performance regarding energy efficiency, fuel economy, and ignition timing.

What to look for when purchasing a Harley-Davidson spark plug

Spark Plugs are designed primarily for motorcycles. These components enhance the bike’s starting power, engine performance, and the bike’s fuel economy. The best spark plugs for Harley-Davidson bikes will keep the engine cool even under tough conditions. The spark plugs that you’re choosing will also maintain or improve the performance of your Harley-Davidson bike. The spark plugs of modern motorcycles have to be replaced after 15,000 miles, depending upon the quality of the spark plugs and when they were replaced the last time.
