Denso Iriidium spark plugs for Prius.
I bought these Iridium spark plugs for my 2011 Prius, this is the exact replacement for a lot less $$$ than the dealer wanted, I can count on it for the next 100k miles, my original set last over 103k miles still works flawlessly, once the new set installed car pick up faster and much better power band merging freeway entrance, so...the iridium plugs DOES degrade in performance and fuel economy. I saved some $$$ by changing the plugs myself, it was a fist and time consuming removing chassis parts in order to gain access to the coils/spark plugs, a 14mm deep socket and long extension is need to get the old plugs out, from start to finished almost 2 hours in my garage, I search YouTube for the how to...video for reference. you need a torque wrench to ensure proper 15 ft-lbs torque. So...amazon rocks for the free shipping and best prices!

No problem so far.
At present, it is still working normally. I'm not sure how long it can be used without problems. We'll talk about it then.

Factory Originals
If your car has these from the factory then replace them with the same...you will survive another 120K miles with these installed.

THE DENSO SC20HR11 IS THE OEM SPARK PLUG FOR THE 2015 COROLLA S
The SC20HR11 is the exact OEM plug that it comes with from the dealer, and its listed on the owner's manual. I don't know why it says it doesn't fit. I replaced mine perfectly. You might want to change that.

Git em
Always excellent sparkplugs, mini recommends 100k, but I find them fouled at 60k. No prob there, cheap enough, and saves gas and money vs. local parts stores

Car is still rolling
Ordered it and got it replaced while I was overseas in Germany...I was having problem with my car, and I thought it was the spark plugs, but it wasnt, but I changed them out anyway, and they still seems to be working so I cant complain.

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.
