Pros and Cons of Iridium VS Platinum Spark Plugs

When air and fuel start to mix inside of the internal combustion chamber, it needs an electrical spark to ignite. The ignition coil is attached to something called a spark plug, which is responsible for forming a high voltage electrical spark that is necessary for igniting the air and fuel mixture of the internal combustion chamber. Once this mixture ignites, the engine turns on after being filled with the combustion pressure.

Iridium VS Platinum Spark Plugs: Pros and Cons

Of course, most people would assume that all spark plugs are the same because they do the same job. The truth is that many spark plug options on the market are different because some are better quality than others and some last longer than others. The two best spark plug options are iridium spark plugs and platinum spark plugs. To help you decide which is right for you, below are the pros and cons of each type of spark plug.

Pros of Iridium Spark Plugs

Below are the top 3 pros of iridium spark plugs.

  1. Long Lifespan – If you want to use spark plugs in your vehicle which will last for the longest time, then you’ll want to use iridium spark plugs. It is estimated that iridium spark plugs will last for at least 40,000 miles but they’ve been known to go up to 60,000 miles or even 80,000 miles. This is the amount of mileage that most people put on their cars before they get a new one. So, an investment in these spark plugs would surely be worth it for this.
  2. Great Durability – Iridium is a silvery-white metal that is harder than platinum. This makes it the hardest spark plug on the market. Because of that, the iridium spark plug has the greatest durability and allows you to get the most use out of it that’s possible.
  3. Less Voltage Needed – When the electrical current is generated from the iridium spark plug, it does not require as much voltage because it has a tiny electrode in the center of it. Whenever there is less voltage used, it means you save on power.

Cons of Iridium Spark Plugs

Below is the only con associated with iridium spark plugs.

  1. Expensive – Since Iridium spark plugs are the best spark plugs on the market, it should be no surprise that they’d also be the most expensive. If you’re someone who is on a tight budget, then you’ll probably want to look for cheaper spark plugs.

Pros of Platinum Spark Plugs

Below are the top 3 pros of platinum spark plugs.

  1. Lasts Longer Than Copper – Many of the features on a platinum spark plug resemble those on a copper spark plug. However, a copper spark plug contains a nickel alloy center electrode while a platinum spark plug has a platinum center electrode. For this reason, platinum spark plugs can last up to 60,000 miles while a copper spark plug lasts up to 20,000 miles.
  2. Prevents Too Much Debris – Platinum tends to get hot a lot faster than other materials. This is actually a benefit to a platinum spark plug because it means the debris that gets on the plug will get burnt up. Whenever you have less debris, you have a smooth running electronic distributor ignition system.
  3. Decent Price – If you want a good quality spark plug at a decent price, the platinum spark plug is priced more affordable than the iridium spark plug. The platinum will still last a long time for the money and you don’t have to resort to cheaper copper spark plugs which have a short lifespan.

Cons of Platinum Spark Plugs

Below is the only con of platinum spark plugs.

Limited Durability – Platinum spark plugs are certainly more durable than copper spark plugs. However, they’re not as durable as iridium spark plugs. This means if durability is a quality that you’re looking for the most, then you won’t get it from platinum spark plugs. You’ll have to go with the iridium instead.
