If you select lower grade spark plugs, you could be missing out on technological advancements that lead to longer life and improved performance. Lesser quality spark plugs can show signs of fouling sooner than premium plugs, meaning that you'll have to replace them more often.
Investing in high-performance spark plugs is a surefire way to save some money in the long run. Better gas mileage is just the beginning. These premium spark plugs last longer than conventional plugs, which means you'll be able to go a longer time between tune-ups, keeping your maintenance costs down.
In most cases, you'll see a noticeable difference in performance after replacing your spark plugs and wires. The engine will run smoother and faster, and the car will have better acceleration. You may also notice an improvement in fuel economy.
Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling.
Finally, new spark plugs can greatly improve your car's horsepower and overall engine performance. When you change your worn-out spark plug with fresh spark plugs, you'll notice a much faster engine response when driving.
Extended lifespan: The iridium spark plugs usually have a longer lifespan that keeps you free from worries for a long time. Enhanced durability: Iridium has a silvery-white metal that is usually harder compared to platinum. The material makes iridium spark plugs the hardest in the market.
The spark plug manufacturers are unanimous about the fact that iridium spark plugs can considerably improve the engine power. The advantage is crucial when you need to navigate through difficult driving situations or climb steep slopes.
Lower grade spark plugs may not be built to original equipment specifications which can lead to many issues including decreased fuel mileage, poor acceleration, engine misfires and hard starts.
At the top of the list, we have the NGK Spark Plugs. With iridium as its core material, this spark plug pack can operate at a much wider heat range as compared to ordinary spark plugs made out of platinum or copper.
The engine won't know the difference. All spark plug manufacturers cross-reference their plugs with other brands so their brand can be interchanged with other brands. For most applications, there are usually a variety of brands that are interchangeable.
Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. This makes ignitions faster and more reliable, and also reduces power consumption.
Performance. The copper spark plug offers the best performance simply because copper is a fantastic electrical conductor and runs a little cooler. An iridium spark plug delivers better performance than platinum but is impacted by high cost.
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium Spark Plugs have iridium center and a platinum ground electrodes.
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.
And we can't overlook the pure alumina silicate ceramic insulator, which provides unmatched strength and heat resistance that give NGK spark plugs a reliable reputation.
To go along with engine fit, most spark plugs get made from different types of metal, some being cheaper than others. However, cheap ones tend to last a shorter lifespan than ones made from more expensive metals. Manufacturers will typically recommend the type of spark plugs your gas-powered vehicle needs.
Iridium is a far stronger metal than platinum, capable of taking up to eight times as much wear and tear as a platinum spark plug before losing efficiency. This means that iridium spark plugs are less likely to fail than platinum spark plugs, need replacing less often, and perform better under tough conditions.
On the other hand, an iridium plug has an iridium tip on the center electrode. Double iridium spark plugs also have a coating on the ground electrode. The iridium electrode inlay is more durable, with a higher melting point that helps increase the service life of a plug.
For this reason, Denso plugs won't last longer than NGK units but they will be better at producing powerful sparks. On the other hand, NGK plugs will be a standard replacement for their platinum alternatives. They require less maintenance and provide a more stable and consistent performance than a Denso.
Ordinary copper and nickel spark plugs should be changed every 30,000 to 50,000 miles, unless otherwise suggested by the spark plug manufacturer. Platinum and iridium spark plugs tend to last longer than standard copper and nickel spark plugs. Expect to change them every 60,000 to 150,000 miles unless otherwise noted.
Electrode Design and Shape is Essential: OEM spark plugs have carefully crafted electrodes that are ground into a specific shape — this process is costly and adds complexity and time to manufacturing. This shape is important to optimize performance and efficiency of the plug.
You can pay between $16 and $100 for a set of spark plugs, depending on the type of plugs you need and the number of cylinders your engine has.
Before attempting to gap any DENSO Iridium Power spark plug, please review the specification chart in the front of this catalog to verify the factory-preset gap. In most cases your Iridium Power plugs do not need to be gapped.
Because iridium conducts energy better than platinum, it's the optimal choice if you want to get the most out of a performance engine. Iridium spark plugs are designed with iridium discs welded to their electrodes. Iridium is six times harder and eight times stronger than platinum!
