to describe fake:

when an item is made by another company other than the OEM and uses the car company's name or OEM brand to its packaging. i.e. parts manufacture by 'peke company' and packages it as 'toyota'

it doesn;t even matter if it is sold at a very low price. that's not the point.

the point here is the trustworthiness of the shop. if it's fake, they should say fake. if it's oem then they should say oem. if replacement then they should say replacement. no beating around the bush and just straight to the point!

at our shop, we sell all original denso parts and other brands. but to your surprise i tell you, not all of them are made in japan! remember, as stated by julian, parts can be made in different countries.

as an example, denso spark plugs are made by 2 countries, japan and indonesia. when my customers ask me where it is made, i tell them where it is really made but i always say that it is made by denso corporation of japan.

when buying from a shop, trustworthiness is the most important factor. this includes services shops especially.

simply put, fake is fake when the seller LIES.

cheers!
