# NGK Spark Plugs: Tractors & Farm Machinery

## NGK Spark Plugs: Tractors & Farm Machinery

710 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.**

Machines that take the same plug are listed together on one line. The equipment type and the fuel or engine fitted are shown with each model — that is what identifies the plug where one model was built in petrol, LPG and natural-gas versions.

**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.

### Diesel glow plugs 163 applications

These models are diesel, so NGK lists a sheathed glow plug rather than a spark plug. 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.

### 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.
