# 3324 Iridium LONG LIFE Spark Plugs -- SK16R11 ----- 4 PCS NEW

Q: Is there a way to determine if these are genuine Denso?

They have the brand marked in the porcelain and came in a denso pack. I have three years of usage in my toyota and runs like new

Q: Do I need to use anti seize lubricant when I install Denso sparks plugs?

In the old days we always used anti seize on plugs going into aluminum heads. Apparently not anymore as a factory certified Toyota mechanic recently stated in a YouTube video that using antiseize is not recommended and can actually cause the plugs to seize up. I checked this out on the NGK site and they state that plugs are manufactured with a coating today to prevent seizing. Applying antiseize to these plugs reduces friction by 20% leading to overtightening and later to seizing. So no, don't use anti seize!

Q: Ya vienen calibradas?

Estás bujías vienen calibradas,

Q: Does this work fine for a 2003 celica gt? not gts one.

I am sure that these will work just fine for you. I have a 2001 Toyota Corolla and since yours has the same motor, they will work just fine. I did have to purchase a couple of coils but they may or may not be required for your peticular application. I do recomend these plugs. Great value and product for the price.
