Always wondered why recirculation mode never seemed to filter out exhaust fumes on my daughters 850. There is no cabin filter. It looks like only LHD drive ones have filter housing adapters that drop into the air intake just in front of the windscreen and they are readily available.
But the LHD insert wont work in RHD car - it's shape needs to be mirror reversed
Is there a RHD adapter available or do I just make one by hacking the original insert and make a filter box out of sheet metal?
