I have a 98 S70, non turbo... I want to replace the MAF (Random Check engine) - it's the original, with 120,000 miles.. so there's a good chance it's n/g... I have found 2 numbers and have not been able to determine if they absolutely are interchangable... Volvo 1275749/bosch 0280-217-107. Also, Bosch B3130-51364. Can anyone advise me on these.. which is correct, are there other numbers, etc... thank you very much! Note- car is away from home at this time, so I am unable to verify either of these on the part itself.. these numbers above are from searching on the net,,,
