I find the sensors for this yr/model non-turbo ...quite expensive. I took the bite for the front....bought Bosch 15057 for $139...thinking not to mess with A/F ration types.
But the rear, for S70/1999 is available as 'Universal ' from Bosch as 15730, w/o connectors[use the old one]...anywhere from $30 to $60.

MY QUESTION: Does this 15730 work both for turbo and non-turbo models...?

The correct Bosch for no-turbo, Rear, with connectors is : 15035 but quite expensive.[same as DENSO 234-4734 with connectors]

my VIN is 55A..
wonder if VIN 55 A needs different type than VIN with 56..
Need help/advice/opinion from those who ve dealt with these.
My cars runs excellent...with 130k...
