What is the difference between NGK spark plugs iridium and platinum?
When it comes to spark plugs, two of the most common materials used are iridium and platinum. While both offer improved performance and longevity compared to traditional copper spark plugs, there are some key differences between iridium and platinum spark plugs that are worth understanding.
Iridium Spark Plugs
Iridium spark plugs are known for their exceptional durability and longevity. Iridium is an extremely hard and corrosion-resistant metal, which allows iridium spark plugs to withstand the high temperatures and pressures inside an engine cylinder. Iridium spark plugs can typically last 30,000 to 100,000 miles before needing replacement, far exceeding the lifespan of traditional copper spark plugs.,p>
In addition to their long lifespan, iridium spark plugs also offer improved ignitability. The fine-wire iridium tip can create a stronger spark, leading to more complete fuel combustion and improved engine performance. This can result in better fuel efficiency and power output.
Platinum Spark Plugs
Platinum spark plugs are another high-performance option that offer several benefits over traditional copper spark plugs. Like iridium, platinum is a durable and corrosion-resistant metal that can withstand the harsh conditions inside an engine cylinder. Platinum spark plugs typically last 60,000 to 100,000 miles before needing replacement, making them a longer-lasting option compared to copper spark plugs.p>
Platinum spark plugs also offer improved ignitability and a smoother, more consistent spark. This can lead to better fuel efficiency and reduced emissions. However, platinum spark plugs are generally not as durable as iridium spark plugs, with a slightly shorter lifespan on average.
Key Differences
- Durability: Iridium spark plugs are more durable and can withstand higher temperatures and pressures than platinum spark plugs.
- Lifespan: Iridium spark plugs typically last 30,000 to 100,000 miles, while platinum spark plugs last 60,000 to 100,000 miles.
- Ignitability: Both iridium and platinum spark plugs offer improved ignitability and spark quality compared to traditional copper spark plugs, but iridium spark plugs may have a slight edge in this area.
- Cost: Iridium spark plugs are generally more expensive than platinum spark plugs, due to the rarity and cost of iridium as a material.
In summary, both iridium and platinum spark plugs offer significant performance and longevity advantages over traditional copper spark plugs. The choice between the two ultimately comes down to factors such as budget, desired lifespan, and specific engine requirements.
Should I upgrade to platinum spark plugs?
The platinum plugs will last longer than copper. This is especially true in the modern ignition systems that apply higher power to the plugs. Or, if you installed a multiple spark amplifier, like an MSD box, they tend to be harder on plugs. So a plug with stronger tips will help them last longer.
What is the disadvantage of iridium spark plugs?
Cons of Iridium Spark Plugs
- Iridium spark plugs are much more expensive than platinum and copper spark plugs.
- In terms of like-for-like performance, an iridium spark plug is on par with a good quality platinum spark plug, which is usually available for less money.
What's better, NGK iridium or platinum?
To actually answer your question, iridums are better than platinum. Iridum is a harder metal, so it holds up better than platinum for long service intervals and iridum is a much better electrical conductor than platinum, making for a better spark.
Is NGK Premium RX better than iridium?
Benefits of NGK RX PREMIUM (VS IRIDIUM) :
- Increased longevity of 20 to 40% compared to NGK IRIDIUM MAX. - Increased longevity beyond double compared to NGK Iridium IX. - Ruthenium undisputed benefits over the stability of the ignition and its corrosion resistance related to combustion effects.
Are platinum spark plugs worth the extra money?
Longevity is a key advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling. Platinum also handles high heat, enabling the spark plug to wear better.
Do NGK iridium plugs make a difference?
Better ignition quality – iridium spark plugs concentrate the electric spark, making it quicker to generate combustion with less expenditure of energy. Each ignition from an iridium spark plug is more efficient than a normal spark plug, and places less wear and tear on the component.
What happens if you use platinum spark plugs instead of iridium?
While you can switch from iridium to platinum spark plugs, it may result in decreased performance, reduced fuel efficiency, and more frequent replacements. If your vehicle is designed for iridium plugs, it's generally best to stick with them for optimal performance.
What is the best spark plug for older engines?
Copper spark plugs
Copper spark plugs are also often used in older (pre-1980s) vehicles with a distributor-based ignition system. The nickel-alloy outer material used in the copper spark plug isn't as hard as other metals so it wears down more quickly with the high pressure and heat created in the cylinder of the engine.
Do NGK iridium spark plugs increase horsepower?
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.
Is there a downside to iridium spark plugs?
Cons of Iridium Spark Plugs
The best models use two or three layers of iridium on the central electrode, whereas the cheapest models may use only one thin layer. These can be prone to cracks and impact damage, so for the best results, always invest in a double or triple coated spark plug.
