# NGK Spark Plugs: Commercial & Industrial Engines ## NGK Spark Plugs: Commercial & Industrial Engines 635 applications from NGK's catalogue, for the machines we supply parts for. Each line gives the plug NGK specifies and the electrode gap. **Plug codes shown as links go straight to that plug on our shop.** Engines that take the same plug are listed together on one line. Match the engine code stamped on the block or the shroud rather than the machine it is fitted to. **Check the gap before you fit.** Plugs are not always gapped correctly out of the box, and the wrong gap causes misfire and hard starting. Where a resistor plug is specified, fit a resistor plug — a non-resistor substitute can interfere with an ignition module or engine electronics. - [Fuji Robin](#fuji-robin) -

Glow plugs have no gap to set. We order these in — call or email with the engine number and we will confirm the right one. Make Models NGK glow plug Kubota KX101 (V1902-BH) · KX151 (V1902-BH) Y-106V D722-B-F-KING-1 (D722) YA01 TD700 (OC62) Y-709R Subaru-Robin DW100 · DW67 Y-113V ### Reading the plug codes An NGK code describes the plug's construction. The digit in the middle is the heat rating — a **higher number is a colder plug**, which is the opposite of most other brands. An **R** after the first letters means a resistor plug. Codes ending **IX** are the Iridium IX range and **G**, **GP** or **P** the platinum ranges, both direct upgrades with a finer centre electrode. Where NGK specifies the solid-terminal build of a plug we show the base code, which is the one we stock — tell us if your leads need the solid-terminal version. Do not substitute a hotter or colder plug to cure a running problem. A plug reading the wrong colour is telling you about the fuel, ignition or oil — changing heat range hides it rather than fixing it. ### Other machines - [Tractors & Farm Machinery](/pages/ngk-spark-plugs-farm-tractors) - [Forklifts & Industrial Tractors](/pages/ngk-spark-plugs-forklifts-industrial) - [Small Engines](/pages/ngk-spark-plugs-small-engines) - [Generators & Lighting Plants](/pages/ngk-spark-plugs-generators) - [All reference charts](/pages/resources) --- > Source: [Sawley's Auto and Marine](https://www.sawleysautoandmarine.com.au/pages/ngk-spark-plugs-commercial-engines)
