87% of mechanics' responses identified NGK as the preferred spark plug supplier. Since being established in Japan in 1936, NGK has always been at the forefront of innovation and technology. They're always exploring new ways to diversify and improve their products so that consumers get the very best!
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. And at $20, it is hard for a lot of the competition to keep up.
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.
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.
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.
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.
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.
While you should buy spark plugs in matching sets for your vehicle, not all spark plugs are universal. Spark plugs come in different sizes with different gaps and are manufactured using a variety of metals. Finding the ones that you need can be difficult.
Standard copper spark plugs last around 20,000 – 30,000 kms. The spark plugs play an important role in your engine, they produce electrical sparks that ignites the mixture of fuel and air in your engine's combustion chambers, causing the pistons to move up and down.
Lubricate Spark Plugs & Other Parts
For part of your car repair and maintenance, you can use WD-40 to remove carbon residue, and keep moisture away from spark plugs and spark plug wires. “WD” stands for Water Displacement.
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode's diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won't last longer than NGK units but they will be better at producing powerful sparks.
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.
With over 80 years of automotive expertise, we are driven by extreme dedication to performance and quality. From OEM to aftermarket, our people push the boundaries of innovation to bring the latest technologies to market under the NGK and NTK brands.
Brush off the plug and firing tip with a clean rag. Spray the firing end with a quick-dry cleaner such as fuel injector cleaner or brake cleaner. Let sit 10 minutes. Use a wire brush to clean off any deposits that have loosened.
Niterra Co., Ltd. NGK Spark Plug Co., Ltd. Niterra is a coined word, which combines the Latin words 'niteo' meaning 'shine' and 'terra/earth'.
When you are replacing your spark plugs, make sure to replace them all simultaneously. This will ensure that your vehicle does not have any complications due to mixing old and new plugs together.
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.
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.
Check and clean sparkplugs every 5,000 miles (8,000 km) and replace them after 10,000 miles (16,000 km). Their condition can tell you about the condition of the engine , and help you to correct faults elsewhere. Always use the type of plug recommended for your car, except as an exceptional and temporary measure.
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.
The main property of the iridium spark plugs is that their electrode material comes with a high melting point. They offer a complete combustion and ensure a better performance. These spark plugs also have amazing longevity, which means you will not have to go on changing the spark plugs too frequently.
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.
A smaller gap will yield a short, intense spark and will usually make the engine real responsive. A wide gap creates a longer spark arc but without sufficient "juice" from your ignition system, (including amps), it can be weak and yellow in color.
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.
