OEM O2 sensor?

I need to replace the bank2 sensor1 on my 09 Tacoma and wondering what’s the best source for OEM replacement. I’m seeing “OE based” replacements at rockauto and elsewhere, but aside from the dealer what’s the best source? Thanks, Dan

I don't have an answer to your question. "OE based" does not mean OEM. It's like saying QEM equivalent.

If you want oem part#'s that you can cross search on rockauto you can use toyodiy.com

 

These DENSO sensors should be the OEM/TOYOTA replacement correct???

Using the ToyoDIY site.

 

That’s what I ended up ordering.

 

Pretty sure I put their Densos and whatnot. Haven’t had an issue since that I’m aware of.

 

Denso is the way. Peace of mind.. just don't buy them from eBay because there are really good fakes with deceptive Toyota packaging and all.
