turboguzzi Posted September 22, 2020 Share Posted September 22, 2020 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.

turboguzzi Posted September 23, 2020 Author Share Posted September 23, 2020 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 Link to comment Share on other sites More sharing options...
