Which spark plug is right for my 2016 TRD OR DC

The denzo website says these both work, but which one do I pick? What would be the Toyota part number of these?

thanks.

 

Owners manual says

 

Thank you!

how do I know which engine I have?

 

2TR-FE is a 4 cylinders
2GR-FKS is a 6 cylinder

 

thank you so much. !

why is denso giving me two options? Could I get the TT model and it would work?

 

Without actually going to the website and looking, I’d say it’s the materials and electrode that are different.

In my experience, you are better off sticking with factory recommended plugs on the Toyota truck engines.

Would the other one work?
Probably would work just fine. But why use it unless you need too?

 

fair point. Yeah I’ll stick to factory recommended, was just curious.
Thanks.

 

Plus the two plugs have a different gap. .040. And .032

 

weird, and they both fit? That doesn’t make sense they would recommend them both.

 

Yes, they both fit.
Whether one is better than the other only applies to vehicles that need a “better” plug.

If your truck needed the other plug. It would have come in it from the factory.

In the case of the 2GR, the difference will be price. You won’t gain anything from using the other plug.

BTW, The difference in the 2 is the style of ground electrode.
