In this video we review how long do ngk iridium spark plugs last and what they look like after 100 000 miles.
Iridium spark plugs life expectancy.
Oe iridium long life plugs ngk laser iridium and denso long life iridium plugs feature an iridium tipped fine wire center electrode and platinum tipped ground electrode.
Twin tip technology enables larger spark concentration and explosion resulting in a more complete combustion and increased fuel economy.
Spark plugs last a long time but they don t last forever.
Therefore the ground electrode will wear out first.
However 100 000km for platinum spark plugs lifespan of iridium spark plugs.
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.
Spark plugs have advanced quite a bit from what they were a few decades back.
A traditional ix iridium plug such as ngk zfr6fix 11 has an iridium center electrode however the ground electrode is a traditional nickel construction.
20 000 km light automobiles.
Denso long life iridium plugs have iridium center and a platinum ground electrodes.
Not sure about the ruthenium hx plugs as they were not around when i contacted ngk about the longevity of the various grades.
Tested to last beyond 100 000 miles with minimal loss to performance.
Long life platinum and iridium spark plugs will typically last up to 100 000 miles or longer provided the engine isn t using oil or doesn t spend a lot of time idling.
Ngk gives them a life expectancy of 40 50k miles.
It is estimated that iridium spark plugs will last for at least 60 000 miles.
Below are the top 3 benefits of iridium spark plugs.
Most spark plugs have a factory service interval of 100 000 miles though some may be as much as 120 000 miles.
20 000 km type normal lifespan type.
Therefore ngk gives them a life expectancy of 40 50k miles and denso assigns a recommended replacement interval of 30k miles.
Some high end iridium plugs are advertised to go more than 120 000 miles 193 121 kilometers but there.
If you are curious if these plugs can last a lo.
Per ngk g power platinum plugs are good for 60k km iridium ix 100k km and iridium laser 120k km.
As the spark plug fires minute amounts of the electrode evaporate.
Nevertheless i expect them to last at least as long as the iridium laser plugs.
You ll find a host of different types on the market from dual and quad tips to iridium tips and many more.
But they have to temper their projections as driving conditions and motor modifications differ.
Not all iridium spark plugs are the long life type there are also some that have the same lifespan as a normal spark plug.
