Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Can I use platinum spark plugs 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. The only issue with iridium is that it costs double the price of platinum with little improvements in performance.
What is the difference between normal spark plugs and iridium?
The difference between the best iridium spark plugs and regular spark plug. Iridium is an extremely durable metallic element, which makes it a great fit as the material for spark plugs. The main property of the iridium spark plugs is that their electrode material comes with a high melting point.
What’s the difference between platinum and double platinum spark plugs?
What’s Better, Double Platinum Or Iridium? In comparing double platinum with iridium, iridium has proven to offer more benefits than platinum. The power of iridium spark plugs makes them 25% longer lasting than platinum spark plugs. Thus, iridium can be concluded as the superior material.
Do iridium plugs make more power?
Greater engine power from iridium spark plugs
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.
Which is best platinum or iridium spark plugs?
Iridium is arguably eight times stronger and six times harder than platinum. It has a higher melting point of about 700 degrees compared to platinum. Platinum spark plugs wear out faster than iridium spark plugs. Iridium plugs are said to be more durable compared to platinum plugs up to 25% more.
Are iridium plugs worth it?
Iridium spark plugs are the most expensive spark plug model on the market, but in many cases they are worth the investment, as the premium price also comes with high performance and reliability.
Should I upgrade to iridium spark plugs?
Starting your car in the winter
Winter starts can seriously decrease your car’s performance, and also run the risk of spark plug fouling. Upgrading your spark plugs to an Iridium fine wire plug will provide instant starts in cold weather and help eliminate the risk of fouling.
Do iridium plugs burn hotter?
Denso Iridium Power plugs feature the heat range at the end of the part number. For example, IK20 has a heat range of 20. Denso plugs get colder the higher the number, hotter the lower the number. Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16.
What is the advantage of iridium spark plugs?
Iridium spark plugs are wear-resistant, so you can continue to drive your vehicle without changing them too often. Moreover, iridium spark plugs have a smaller fine wire center electrode than a standard copper spark plug. This helps ensure a more concentrated spark to power an engine faster.

How often should I change iridium spark plugs?
Conventional spark plugs need to be replaced every 30,000-50,000 miles. Long-life (iridium- or platinum-tipped) spark plugs need to be changed between 60,000 and 150,000 miles, depending on the vehicle.
How long do NGK iridium plugs last?
40-50k miles
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.
How do I know if iridium plugs are worn?
Signs that the best iridium spark plugs need replacement

Do NGK iridium plugs need to be gapped?
Iridium Power Gapping Tips
In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations.
Which is better NGK or Denso spark plugs?
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.
