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.

What spark plug is better NGK or iridium?

Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. This makes ignitions faster and more reliable, and also reduces power consumption.
