Do NGK spark plugs make a difference? This would be more accurately described as “less performance loss.” Spark plugs do not increase the performance of an engine — even spark plug manufacturers are fairly forthright about that. They won't make the engine perform better than it did when it was new, but they will help it stay at that level longer.
Why are NGK spark plugs better?
NGK 6619 Iridium IX Spark Plugs snagged the top pick in our spark plug comparison because they offered the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
What spark plugs are better than NGK?
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 Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.
How long should NGK spark plugs last?
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.

Are copper spark plugs better than iridium?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
Can I use platinum instead of iridium?
Platinum may be harder than copper, but iridium is the hardest among the three, and iridium spark plugs outlast platinum spark plugs by almost twice the mileage. Platinum spark plugs offer a slightly cheaper but less reliable option if you don't want to spend as much on iridium spark plugs.
Do iridium spark plugs burn hotter?

Does changing spark plugs improve performance?
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle's performance. New spark plugs help keep your engine at its peak performance and efficiency levels. Worn or dirty spark plugs require higher voltage to get a strong enough spark to start a vehicle.
Should you lubricate spark plug threads?
NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. It's very important not to over or under tighten spark plugs during installation. Over tightening can lead to distortion of the spark plug and breakage.
