# LMAR6A-9 NGK Standard Resistor Spark Plug | Genuine NGK Spark Plug

## 🔧 Product Description

**NGK Standard Resistor Spark Plug – Part Number: LMAR6A-9**

NGK iridium spark plugs feature an iridium alloy on the centre electrode, welded on with a laser – one of the world's hardest metals, with a melting point of 2450°C, giving very high resistance to spark erosion and, on average, double the service life of a standard nickel spark plug.
