Bosch upstream o2 sensor

[T4Rscott]

Hi all,

First of all, I hope everyone is doing well during these challenging times.

I’m going to have to replace the upstream A/F ratio sensor (o2 sensor). I have gone to both Denso and Bosch websites. I’m leaning toward the Bosch because it’s cheaper. However, Bosch gives me a part # of 13613. When I go on Amazon it states it doesn’t fit.

Are any of you out there running a Bosch sensor that can confirm if the 13613 fits and works correctly?

This is for a 99 3.4L auto Cali emissions.

Thanks and stay safe,
Scott

Personally, I use Bosch in my German Westfalia and Denso in my Japanese 4Runner.

Looks like that Bosch number is good, and the Denso equivalent is 234-9002. The Denso is $120 at rockauto.com, whereas the Bosch is $140.

I have an NTK for my front sensor. It’s doing just fine.

Edit: although I’ll admit half of me wants to buy the OEM Denso and see if anything happens to mpg.
