Iridium or platinum plugs

Iridium is up to six times harder than platinum so Iridium should hold up longer when used on your spark plugs. Therefore manufacturers are constantly working on this element improving it.

All dual precious metal plugs are designed to provide maximum longevity.

Iridium or platinum plugs. Platinum spark plugs offer a slightly cheaper but less reliable option if you dont want to spend as much on iridium spark plugs. It yields decent longevity but ranks the poorest in performance. Platinum spark plugs are also recommended for cars with an electronic distributor ignition system while double platinum spark plugs best fit vehicles with a waste spark distributor ignition system.

Iridium is a silvery-white metal that is harder than platinum. This makes it the hardest spark plug on the market. Because of that iridium spark plugs have the greatest durability and allows you to get the most possible use out of them.

3 Less Voltage Needed. Iridium spark plugs are known for lasting up to 100000 miles. Thats quite a lot more than platinum spark plugs.

In fact some people even say that their iridium spark plugs last even 120000 miles. When you really think about it 120000 miles is a long way. Iridium spark plugs and Platinum spark plugs are pretty similar in their overall design but they have one key difference which is the material the tip is made of.

Iridium is up to six times harder than platinum so Iridium should hold up longer when used on your spark plugs. Platinum and iridium spark plugs are the products of more modern technologies as the use of these metals in the process of electodes manufacturing significantly increases the service life of the element. For example a platinum spark plug which is properly selected for the engine even on bad fuel can live 25-30 thousand miles of run.

The most common types of spark plug types are the copper spark plug iridium spark plug platinum spark plug and double-platinum spark plug. Weve crafted a handy list for you which includes the difference in materials used and the differences in efficiency and cost. Platinum plugs are good for 60000 miles.

Iridium plugs ae good for 100000 miles. Id use the Iridium plugs if the intake plenum has to come off. In the real world though youre unlikely to see any measurable change in fuel economy using iridium instead of platinum plugs.

Platinum will do everything iridium does outside of the most severe racing applications. Iridium can give engine builders a slight edge in very high-compression turbocharged or supercharged engines but this edge isnt likely to translate into increased fuel economy in a street engine. Iridium is harder than platinum and in most cases iridium spark plugs last about 25 percent longer than comparable platinum spark plugs.

Because iridium is costly iridium spark plug manufacturers reduce the diameter of the center electrode to as little as 4mm. You may use the double-platinum as an upgrade. This applies to the double-platinum if your car manual recommends them do not downgrade to single platinum or copper but you may use the iridium spark plugs.

Advantages of Platinum Spark Plugs. They last much longer than copper spark plugs and give a better performance going up to about 25000 miles. Consumers have a choice when selecting the material on the tip of the electrode for the spark plug.

You can have an iridium or a platinum tip to optimize the units performance. Iridium is approximately eight times stronger and six times harder than platinum. Platinum spark plug is a golden mean between copper and iridium ones.

Platinum has twice better longevity than copper and fairy low price. Platinum disc and central electrode tip provide slow wear rate and better fuel efficiency. Though platinum is less conductive than other materials so platnum spark plugs but performs at a lower level.

I put genuine NGK iridium plugs in mine with the intention to go at least 100K without a problem. For most cars I consider a GOOD platinum plug for only 60K. For the total expected use time and mileage I dont consider the difference in price to be a factor.

I go with what the factory put in. Posted via the PriusChat mobile app. Spark plugs are an important element in a car engine.

Much depends on their job stable operation ignition both cold and hot fuel consumption and even power. Therefore manufacturers are constantly working on this element improving it. One of these evolutionary leaps was iridium spark plugs some call it platinum.

NGK builds two types of iridium spark plugs. OE Iridium and Iridium IX. Every plug in the Laser Series was designed for an OEM application.

All dual precious metal plugs are designed to provide maximum longevity. For the OE Iridium series dual precious metal means iridium on the center tip and platinum on the ground electrode. Spark plugs made from iridium are the best components you can use.

Iridium is stronger and lasts 25 longer than platinum spark plugs. Iridium is quite costly and as a result manufacturers produce electrodes that are 4mm in diameter which is smaller than other spark plugs. NGK IridiumPlatinum Spark Plug DILKR8B6.

We are an online based store that sells suspension parts lifts shocks of various manufacturers at affordable prices and fast shipping. Delivering the best products service in the fast manner possible. Parts are sourced shipped from several.

Iridium spark plugs last the longest since iridium is harder and more durable than platinum. These spark plugs have a small center electrode which requires less voltage to generate a spark. These advantages are reflected in the higher price tag.

As you may already have figured out platinum plugs use platinum while iridium plugs use iridium for the tip of the center electrode. Iridium plugs cost more than platinum plugs partly because iridium is a rarer metal than platinum but also because it offers several advantages.
