Well, after replacing my upstream Lambda sensor with an OEM quality Denso DOX-0307, just two years/20K miles  ago,  It is kaput again.

It’s been in a 2005 2.0 euro forester

before jumping to buy another Denso, was wondering if there are better alternatives?

A cross reference check gives it as a replacement for

22641AA140,22641AA230,22641AA280,

So far the only one I found is this

https://www.amazon.com/Blue-Print-Lambda-Sensor-ADS77008/dp/B00B8YMD34

if anyone has a better idea, I'd love to hear.

Thanks in advance

NGK or Bosch/.

O.

The OEM sensor is manufactured by Denso.

hmmmmm....vacuum leak overheating it???? or , can they be 'poisoned' by coolant in the exhaust or ????

yes, i know OEM is Denso, thats why it sucks that mine failed in two years.

no coolant in exhaust, car is not consuming any...

need a new one anyway, ngk seems more affordable, might give it a try
