Iridium Spark Plugs Life Expectancy
You ll find a host of different types on the market from dual and quad tips to iridium tips and many more.
Iridium spark plugs life expectancy. Denso long life iridium plugs have iridium center and a platinum ground electrodes. Spark plugs last a long time but they don t last forever. Nevertheless i expect them to last at least as long as the iridium laser plugs. Well standard copper plugs are said to last anywhere from 10 000 to 20 000 miles 16 093 to 32 187 kilometers while more expensive iridium or platinum spark plugs can last 60 000 miles 96 561 kilometers or more source.
The primary reason that spark plugs need to be changed is due to wear and tear. 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. 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. Not sure about the ruthenium hx plugs as they were not around when i contacted ngk about the longevity of the various grades.
But they have to temper their projections as driving conditions and motor modifications differ. Some high end iridium plugs are advertised to go more than 120 000 miles 193 121 kilometers but there. Most spark plugs have a factory service interval of 100 000 miles though some may be as much as 120 000 miles. Therefore ngk gives them a life expectancy of 40 50k miles and denso assigns a recommended replacement interval of 30k miles.
Tested to last beyond 100 000 miles with minimal loss to performance. In this video we review how long do ngk iridium spark plugs last and what they look like after 100 000 miles. As the spark plug fires minute amounts of the electrode evaporate. 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.
A traditional ix iridium plug such as ngk zfr6fix 11 has an iridium center electrode however the ground electrode is a traditional nickel construction. Per ngk g power platinum plugs are good for 60k km iridium ix 100k km and iridium laser 120k km. If you are curious if these plugs can last a lo. However 100 000km for platinum spark plugs lifespan of iridium spark plugs.
It is estimated that iridium spark plugs will last for at least 60 000 miles. If installed in a regular engine they would likely. Ngk gives them a life expectancy of 40 50k miles. Therefore the ground electrode will wear out first.
Twin tip technology enables larger spark concentration and explosion resulting in a more complete combustion and increased fuel economy. Spark plugs have advanced quite a bit from what they were a few decades back. 20 000 km light automobiles.
