As mentioned here, I am getting different readings from my AFR sensors, so one/both are on the way out.
Does anyone have any experience with cheap Chinese AFR sensors (e.g. this on Aliexpress or this on Amazon). OEM is $150 USD on Partsouq and Denso $110 USD on Amazon before shipping, so the Aliexpress one is less than half the price.
I know the standard answer to these questions is "go genuine, not worth the risk etc..", but I would love some insight into what the difference in quality, if any, actually is? Plenty of things competing for a scarce amount of money at the moment and I would likely replace both sensors...
