NGK Laser Iridium Spark Plug

Iridium is one of the hardest metals known and can resist extreme temp and pressures

This makes them ideal for modern lean burn motors, the fine point electrode gives an improved spark and resists fouling

The iridium tip is laser welded to the conductor core for reduced resistance and high performance/service life

The service life is estimated at 50,000 KM so do not require changing at normal annual service

Listing is for a single spark plug

NOTE – Beware of anywhere that sells these too cheap, there are lots of fake copies around.  Even on large online retail marketplaces.
