O2 sensors

Trying to figure out the right brand to fit in my 08 legacy to avoid anything weird with the main computer the two brands I find are Bosch and Denso which is the OE Subaru uses.

I've owned my car since it was new, and the upstream oem sensor that I removed from it a couple years ago says Denso on it.

both are reputable brands that will be fine as replacements.

Bought 2 new 02 Sensors from rockauto yesterday for my build (139 shipped with coupon), both Denso. Make sure you get the right ones for your car. there is a diff between 5mt and 5EAT ones.

 

Also do not Sleep on NTK sensors they work great. I had to put on in on my wifes 2013 legacy a week after I bought it used. People love to say OEM Subaru only or this and that. I am that guy who buys a part no one will and it has always worked great. Have to really dig In and research.

There are a couple post there with the correct Denzo #.

 

Oh, I have it written down in the note book I keep for the car. Front Denzo 234-9120

 

I don't think there's a difference between 5mt and 5eat ?

Here is the rockauto ones I got:

 

DENSO 234-9120 {Click Info Button for Alternate/OEM Part Numbers22641AA211, 22641AA32A, 22641AA490, 32010411}

Upstream

 

DENSO 2344446 {Click Info Button for Alternate/OEM Part Numbers22690AA500, 22690AA501, 22690AA53B, 22690AA69A}

Downstream; Manual trans (There is one for Auto Trans)

Willing to bet the only difference is the cable length. Wouldn’t imagine the connectors could be different.

I think your right, but I do not want any problems at the tuner and shop lol.

That's only for the rear O2 that is longer on the 5eat's, I'll assume.

 

Which I believe the Tuner can delete ? So you don't need to replace it when it fails.

 

 

I also see the Spec B's rear O2 is 234-4732 for $39.00 on Amazon

The 234-4446 rear for a 5mt is $50.00

 

Looks like the Spec B's also fits a 5eat.

yes, the 6mt and the 5eat DP are the same length IIRC while the 5mt DP is different. that would call for sensors with different cable lengths, hence the different part #'s

I believe both 5mt and 6mt DP are the same. I have both in the basement. The 5eat DP has a bracket in a different location.

 

Yes, just checked the two DP look the same to me. The O2 location is the same.

 

The picture looks different then in person, I did move the closer pipe today so the turbo flanges are equal. I believe in this picture they were not aligned, that's why the 5mt DP looks longer at the midpipe flange.
