My rig is currently in need of a new muffler again (I'm on my 2nd or 3rd Bosal......can't remember)

It's been leaking at the bung on the pipe for the O2 sensor, so it's possible the sensor is bad as well as she recently threw a code :confused:

I usually stick with OEM when it comes to O2 sensors, but while shopping for a new muffler, I saw that API has them for under $12 bucks with pigtails at Rock Auto :oops:



Now, I'm hoping my current O2's are still good, but I wouldn't mind having a backup just in case they're shot :hmm:

Some of you might remember when I first installed a complete Bosal setup, one O2 crapped out on me after having to use an air chisel to remove it :doh:

It shorted out, causing the EFI fuse to constantly blow :bang:

I ended up having to unplug it until I could get a new one at the dealer the next day :meh:

Just curious if anyone here has used them before....

Denzo is the OEM and are pretty cheap no? I’ve actually had worse results using more expensive Bosch and the like, ie throws codes, etc. where as NTK / NGK and Denzo just seem to work.

I have never used those ones, but in general I have never had any luck with cheap O2 sensors, for any vehicle I've ever owned. YMMV.

Curiously, I've been scouring today posts searching for the thread that answers this; I forgot to bookmark it. IIRC, replacement Denso sensors can be had for about $15 (in last year's money).

NTK is OEM for the 94 and olders, Denso for 95+

Either are reasonably priced. I've learned that cheap parts especially ones that see harsh environments like and O2 sensor are best purchased once.

Clearly everyone is saying Denso/OEM so I am just reiterating that point when I say I put an aftermarket one on my Tacoma and it crapped out in 2 weeks. Buy once cry once as they say.
