Denso O2’s

Just for those who didn’t know - Amazon has OE Denso O2 sensors for $50/each. Dealer, Autozone, etc sells them for $105+ each. Not my find, Timmy the toolman had them on a video mentioning it. Save some cash!

Denso PN:

$51 234-4162 Oxygen Sensor with 4-Wire 10.5” Harness for Non-California, Non-4WD Lexus/Toyota

234-4162

(non-ca emissions) aka single cat up to 2000 and part is same for front and rear 02’s. The 2001+ 02’s are much more expensive and specific to before/after cat.

Wanted to wait until I get them in the truck to confirm, but they’re legit. Come with gaskets as well.

 

You should compare these to the original ones, because Amazon and Ebay are notorious for selling fake parts.

 

If it doesn't have a Toyota part number, it is NOT OEM.

oops

 

You have to check out the ebay/Amazon sellers.......some are not real oem

might be worth an extra nickel to be safe

the ones you have there could be just their 3rd party vendor packaging for the different part stores
.......you know the ones that double the price

 

I was suspicious of that too until I saw multiple online Denso distributors selling them for the same price. They "feel" identical to my old ones in my hands, no "chineseum" feel, very solid. No codes thrown (yet), i'll let ya know.

 

Could be. Not disagreeing. Took a little chance...

As someone with NOTHING but true OEM parts on my truck with another $1000 spent on them this week alone, i'll give these a shot. The Denso etched number on it does not match Denso's part number though... not sure if that's just for the metal casing.

 

If they’re sold and ship by Amazon, more likely they’re legit

If they’re sold by a third party but ship by Amazon, more likely they’re knockoff

In this case, look like they’re sold and ship by Amazon.

 

It was indeed sold and shipped by Amazon.

 

I put two Denso O2 sensors on my V6 4Runner from Rock Auto. The Bank 1 cat was fine. Very high quality and darn near identical to the O.E. Toyota parts. I'd buy O.E. if they were reasonably more expensive but the dealer wants four times the price for both upstream and downstream. Screw Jeff Bezos, buy from Rock Auto.

 

I feel way better ordering it from Rock auto. I just ordered the same last month and it was $52 from them.

Wouldnt worry much about o2 senors......worst case scenario
just dont last as long...

Engine sensor's I'd be more careful with
......worst with those o2's if they thro a code.......then you just return em....no big deal


slather high temp anti seize or something over those studs and nuts......make em last as long as you can

 

Brand new studs + nuts too. Collecting part #s like bitchy ex wives
