I’ve got an old beat up snow blower that needs a new plug for the Tecumseh Sno-King engine.
There is a Champion plug in there right now with the model number RJ19LM.
The easiest way to find the AMSOIL NGK plug stock number is to use the NGK Plugs and Wires Cross Reference found on the right side links of the amsoil.com website.
Type in “RJ19LM” into the Manufacture Part Number text box and click the “Cross Reference” button to look for matching plugs/wires.
It will return a table similar to this or an empty table if a matching product can’t be found:
| Part Type | NGK Part Number | AMSOIL Stock Code |
| Plugs | BR2LM | NGK5798 |
