Frequently Asked Questions
What is the difference between iridium and platinum spark plugs on a Subaru?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
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.
Which is better, Denso or Ngk iridium spark plugs?
NGK Plugs are better. They have better threads and the Denso have been known to fall apart in Turbo applications. I went thru this when I replaced the plugs in my Hondas.
Is it better to use OEM spark plugs?
Always use OEM sparkplugs on cars. The reason is that the electronic engine control system is tuned to the specific load of that plug.
Is NGK platinum better than iridium?
Keep in mind that while iridium is stronger, it's nearly double the price of platinum. On the other hand, if you're hoping to save money, it's advisable not to downgrade the type of spark plugs because this can affect the performance and longevity of your vehicle.
