Do you know if this spak plug is manufactured in Japan or in China ? Thank you !!

It says that it is made in Japan on the box and on spark plug as well.

Does this need anti-seize grease?

I always put a little bit of anti seize on spark plugs as they are almost always in aluminum heads. If the aluminum corrodes it ain't coming out.

It's a SC20HR11 code?

Yes, this is the aftermarket part number for the original Denso plug #SC20HR11Bruce

Denso Iriidium spark plugs for Prius.

Falschlieferung

Anstelle des bestellten Zündkerzen-Satzes (4 x Denso SC20HR11) wurden 3 verschiedene Arten von Zündkerzen zugeschickt. Bei zwei Kerzen war sogar die Schraubengröße und das Gewinde völlig unpassend... Sehr ärgerlich und vollkommen unnötig.

BUJIAS SC20HR11

Lo califique con 2 estrellas por qué dude de la originalidad de producto, ya que uno dice hecho en Japón y el otro en china! No me dió buena pinta. Cajas muy diferentes y bujía también diferentes. No lo recomendaría, las devolví.
