NGK spark plug lookup tool

Whether or not you use NGK spark plugs in your lawn mower or other power equipment, you can use the NGK spark plug lookup tool to see which spark plug your mower takes.  This reference can come in handy if you've lost your engine manual, and you're not sure what the proper gap for your plug should be.  The NGK chart will show the NGK part number for your spark plug, as well as what the gap should be.  All you need are the make of the mower and either the engine model/size or the mower model.
