Echo A425000000 Replacement: Compare 2 Options

How to find your model number

Check your model number before you buy a replacement for the A425000000. Engine parts are matched by the engine model, not the mower model.

• Briggs & Stratton engines: the model, type and code numbers are usually stamped on the engine shroud or on a sticker on the blower housing.
• Kohler engines: a label with the model, specification and serial numbers is usually on the blower housing.
• Honda engines: the engine type (for example GCV160) is usually cast or printed on the engine block, with the serial number nearby.

Spring maintenance

Fit a new spark plug at the start of the season, gapped to the engine maker's specification.

Maker's part vs aftermarket: the A425000000

We did not find Echo's own A425000000 on Amazon. 2 brands sell a spark plug listed as its replacement, including Hipa, Yistiun.

• Maker's own part: made and sold by the equipment or engine maker (for example John Deere, MTD or Briggs & Stratton). Usually the highest price.
• Aftermarket parts: made by other companies to the same size and fit. Usually cheaper; materials and build quality vary by brand.
• Before you buy: find your equipment's model number (see How to find your model number, above), compare the size of your old part, and confirm the fit on the product page.
