Then how does Iridiums compare to double platinums? I was told single plats will last 50k and double 100k to match Iridiums

+1 Platinum is really only good from a durability standpoint but iridium allows for a much finer electrode tip which gives a more consistent spark and creates a smaller «shadow» as the flame front propogates away from the spark.

Platinum isn’t as good as a conductor as iridium. So it goes Performace: 1. Copper 2. Iridium 3. Platinum Longevity: 1. Iridium 2. Platinum 3. Copper

Be cautious about ‘blanket’ recommendations. Modern cars have very sophisticated ignition systems designed for a SPECIFIC type of plug. Some cars are not very tolerant of changes in this area. I recommend you run the exact OEM plug that shipped with your car when new.

Canadian’s get ripped off for just about everything. Grab your plugs from rock auto or autopartsway, forget Canadian Tire and Part Source.

I have read some of the marketing that the fine wire iridium plugs are easier on ignition components. wich would not matter in a car as much as an aging string trimmer or old atv or motorcycle. I have not the knowledge or the inclination to know if there is any merit to this. I run them in some dinosaur ATVs at the farm.The relatively weak coils and stators in these, and their difficulty in finding replacements, I spent a few extra $. I have noticed no difference in performance or fouling.

More years ago than I would admit, I had a old 2 cycle motorcycle that we removed the oil pump from and thereafter ran gas that had the oil mixed with it. That bike would foul a plug in about one or two days of riding until I put an iridium plug in it. That plug never fouled. It was driven several years with that plug and it never fouled, and when I sold it that plug was still in it.

For what its worth even single platinum plugs will last immensely long. If you really are bothered by changing plugs and don’t want copper, I say just go platinum, as a lot of cars have them anyhow. Double platinum just puts platinum on the ground electrode. That is great, but the plain ground electrode is so huge compared to the active electrode its enormously unlikely to burn out to any measurable amount. The rest is well, marketing. I think iridium plugs are sort of insane, *UNLESS* you have some car with an absolutely tedious and god [censored] ridiculous spark plug changing procedure. some cars require you to almost remove the engine to change plugs. I’d use iridiums there in a heartbeat just in the hope they last long enough that I basically never would have to mess with them. But in your regular car, use copper, or regular platinum. the rest are kinda the grey area where you get played a bit for nothing really measurable.

Because it would have been less of a troll if it was correctly placed.

I use whatever the owner’s manual says. The spark plugs I used for my Buick (Every 100,000 miles): http://www.oreillyauto.com/site/c/detail. 5&ppt=C0334 The spark plugs I used for my Chrysler (Every 30,000 miles): http://www.oreillyauto.com/site/c/detail. 5&ppt=C0334

Interesting. I used to install platinum plugs in my 89 Accord so I could use them for twice as long. I know a number of vehicles use them to extend the maintenance intervals. The Mazda «Skyactiv» engine requires iridium plugs with platinum on the ground electrode presumably due to the higher than average compression ratio (12:1). Iridium is a rare element that exists on this planet due to asteroid collisions. I would venture to say that if your car does not require iridium plugs they are a waste of money. Platinum plugs may not be because they do last about twice as long as conventional plugs. Other than that, I can only speak from my own experience which seems to say that any plug that ignites the mixture in your cylinders consistently is fine. This is what is known as anecdotal evidence. That term describes the majority of what you will read in ANY forum.

funny thing. I’ve only ever used Platinum plugs for a long time. This last time, however, I put a set of iridium plugs in 2 separate vehicles; both vehicles had previously ran NGK platinums and were switched to NGK iridiums. and all I can say is. WOW! It is not a marketing scam for higher price results; I for one truly see the results. Much smoother idling, take-off power, mpg, engines are quieter. just overall an improvement worth it IMHO. Both vehicles previous plugs were only 25-30k miles respectively; one vehicle is a 97 3.2L Isuzu (does not burn/use oil), the other vehicle is an 04 3.4L tacoma

Cars that use waste-spark ignition, or other applications where the spark goes the opposite way of usual can benefit from double-platinum plugs.

First, note that ALL PLUGS are copper core. The only part changing is the electrodes. Second, iridium/platinum hybrids are not just for Mazda or for high compression engines. They shipped stock in my car manufactured in July 05! They are easier to fire and last longer. Choose your plug by how often you want to play with them, just be careful as modern cars are a bit quirky sometimes, so no advice is ‘blanket’.
Spark plugs are essential components of every vehicle that plays a vital role in the combustion process, enabling the vehicle’s engine to start and run properly. Your car’s engine performance and efficiency are partly dependent on the kind of spark plug you use. Most spark plugs are fitted with a copper-core center electrode, which is an incredible conductor of electricity. It is better than other kinds of materials used in making plugs, and it also offers good heat transferability. The copper area of a spark plug is usually protected with a nickel alloy because of its softness and low melting point. In order to optimize performance, the electrode may have a platinum or iridium tip, depending on the kind of plug. Let’s take a look at iridium vs. platinum Spark Plug to be able to ascertain the differences and the most suitable for spark plugs.
What is Iridium Spark Plug?
The iridium spark plug is an excellently durable spark plug made with a metallic element that provides great performance and efficiency and possesses a high melting point. Iridium is an incredible metal that comes with lots of great features. Iridium has the potential of lasting for a long time, which helps to maintain the longevity of the spark plug so that you don’t always have to replace your car’s spark plugs. Iridium spark plugs are wear-resistant, with an amazing consistency by natural orchestration. They are some of the best spark plugs you will ever find. Other conventional spark plugs cannot be compared to iridium because of their extended lifespan, durability, and concentrated spark. The plugs power vehicle engines faster than many other plugs because of the concentrated spark projected by the small electrode at the center.
What is Platinum Spark Plug?
A platinum spark plug is synonymous with copper spark plugs, with a slight difference in the center electrode, which is made of platinum, welded to the tip of the electrode. The platinum enhances the durability of the plug, enabling it to last for as long as 100,000 miles. Platinum spark plugs generate more heat than their counterparts, and as a result, they ensure the reduction of building-up debris. This kind of spark plug is recommended for you if you own a new car with a system of electronic distributor ignition.
Iridium Vs. Platinum Spark Plug Differences
Iridium is quite different from platinum in strength, performance, durability, and the degree of melting point. 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.
Iridium Vs. Platinum Spark Plug Materials
Iridium and platinum materials are both excellent materials used in the advanced types of spark plugs, making them better than regular spark plugs. However, iridium is more expensive, stronger, and harder than platinum. The strength displayed by iridium is incredibly greater than that of platinum; hence, iridium has the capacity of lasting longer than platinum up to 25% extra longevity gap. If you are looking out for a very solid spark plug that offers great strength, higher melting point, excellent performance, as well as top-notch efficiency, consider iridium spark plugs. However, they are more expensive than platinum and other normal spark plugs.
Iridium Vs. Platinum Spark Plug Price
If you are contemplating iridium vs. platinum price, the price of iridium varies from that of platinum because one is a more valuable metal with higher quality than the other. The average price of iridium as of 2020 was around $2,550 per troy ounce. As of March 2021, the cost of iridium took a surge to $6,000 per troy ounce. Meanwhile, platinum currently costs around $1,015 per ounce, making iridium almost six times the price of platinum. Hence, iridium possesses more capacity in every area than platinum.
Iridium Spark Plugs Vs. Normal
Iridium spark plugs differ from normal spark plugs in every way. The electrode material of iridium spark plugs has a higher melting point, and the plugs are more durable, with greater performance and efficiency than regular plugs. In comparing iridium spark plugs vs. normal, a normal spark plug could last as much as 20,000 to 30,000 miles, as the case may be, and the average annual mileage of car owners in America is said to be around 13,476 miles. Therefore, a regular plug is likely to last between 1.5 years and 2.25 years respectively.
Platinum Vs. Iridium Spark Plug Performance
Platinum has a great performance level compared to other regular spark plugs, but compared to iridium, the difference is clear. Iridium has a more excellent performance in igniting the air and fuel compression within the combustion chamber. This is one main reason why platinum vs. iridium performance differs. Iridium is more efficient than platinum, with many advantages to prove that it is better than platinum. If you are asking how long do platinum spark plugs last, they can last up to 100,000 miles; iridium lasts beyond 100,000 to 120,000 miles. You may not necessarily have to change your spark plugs if you use iridium.
Iridium Vs. Platinum Pros And Cons
Iridium and platinum spark plugs vary in their features, performance, and efficiency. While iridium seems to be stronger than platinum, it still has its cons. You must ensure to find out the pros and cons of both iridium and platinum before making a final decision on which of the plugs to buy for your vehicle.
Pros Of Iridium Spark Plug
- It is harder compared to platinum.
- It uses less voltage in operation.
- It lasts longer than most spark plugs, including platinum.
Nevýhody
- It is relatively expensive compared to platinum and many other spark plugs.
