Original or compatible?

A generator's air filter and spark plug follow its engine and model: Honda and Yamaha name both per model in the owner's manual and parts list. Genuine parts come from the maker through its dealers; compatible air filters name the generator models or the maker's part number, and a spark plug is the type the manual names (NGK, Champion or Denso).

Where the model number is

The model is on the label on the generator's side panel or frame (Honda EU22i, Yamaha EF2000iS), with the serial number, and in the owner's manual.

Why change it on time

A clogged air filter starves the engine of air, so it loses power and is hard to start; a worn plug makes it misfire. The owner's manual gives a schedule in months or hours of use, sooner in dusty places.

How this list is built

Every fit comes from the manufacturer's own compatibility list or parts page, with the source recorded on each row. Where only a seller lists a fit, the page says so. Prices are re-read from each seller's page daily where they publish one, and dated. How FitMatch checks fitment.
