What is the difference between iridium and platinum spark plugs Subaru?

Difference Between Iridium and Platinum Spark Plugs for Subaru
When comparing iridium and platinum spark plugs for a Subaru, there are several key differences to consider:
1. Material Composition:
– Iridium spark plugs are made of iridium, which is more expensive, stronger, and harder than platinum. On the other hand, platinum spark plugs are made of platinum, which offers great performance but is not as strong or durable as iridium.
2. Performance and Efficiency:
– Iridium spark plugs offer great strength, higher melting point, and excellent performance, making them a solid choice for Subaru engines. They use less voltage compared to platinum and copper spark plugs, and their narrow electrode tips prevent sparks from extinguishing.
– Platinum spark plugs also provide good performance but are not as strong or durable as iridium. They are efficient and offer longevity compared to standard copper spark plugs, but the difference in performance compared to iridium is clear .
3. Cost:
– Iridium spark plugs are considerably more expensive than platinum spark plugs due to the scarcity of iridium and its superior properties. The price range for iridium spark plugs is typically between $8 and $15 each, while platinum spark plugs cost approximately half that amount, ranging from $4 to $8 each.
4. Longevity:
– Iridium spark plugs can last up to 25% longer than comparable platinum spark plugs due to their strength and wear characteristics.
– Platinum spark plugs also offer increased longevity compared to standard copper spark plugs, but they are not as durable as iridium spark plugs.
In summary, while both iridium and platinum spark plugs offer improved performance and longevity compared to standard copper spark plugs, iridium spark plugs are more expensive, stronger, and more durable than platinum spark plugs, making them a preferred choice for Subaru engines.

Do iridium spark plugs increase horsepower?

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.

Are iridium spark plugs worth the extra money?

On top of that, the electrical resistance of iridium is better than copper, which also adds to its performance and longevity. The iridium plugs might cost slightly more than the copper spark plugs, but it’s still worth it because you’ll be paying for quality.

Does iridium spark plugs make a difference?

Iridium spark plugs are capable of working at higher temperatures, as iridium has an impressive melting point of 2,426°C, as opposed to 1,085°C for copper. Better ignition quality – iridium spark plugs concentrate the electric spark, making it quicker to generate combustion with less expenditure of energy.

What is Subaru OEM spark plugs?

OEM Subaru spark plugs are made to offer optimum performance since they are constructed from the best porcelain and metals. OEM Subaru spark plugs last as long as the original spark plugs in your Subaru.

Should I use platinum or iridium spark plugs?

The benefits of iridium for a spark plug include: It’s as much as eight times stronger than platinum, so iridium can have a sharper center electrode that conducts a more durable, powerful spark. Iridium is much harder than even platinum, so it resists wear for up to 25% more lifespan.

What are the disadvantages of iridium spark plugs?

Disadvantages of Iridium Spark Plugs
You can expect to pay around triple the price of copper spark plugs, and it doesn’t always improve how well your engine runs.

Do iridium plugs add horsepower?

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.

Do iridium spark plugs give better gas mileage?

It does not matter what material the plug is be it copper, platinum or Iridium. You will not gain power, MPG’s or better emmisions from a certain type of plug. HOWEVER, over time and miles a long life plug (plat/irid) will continue to run cleaner and better than a standard copper plug.

Why are Subaru spark plugs so expensive?

Because of the cost of iridium, the electrode is thinner, but they still deliver better power, better combustion and longer life than other plugs.
