Any issues using oil-based filters on 1.1 fire engines? Mine is 141a 4x4 panda 1108. Does it habe air mass flow sensor that could get dirty from oils coming from air filter?

I was running a BMC filter on my old Cinquecento which had an SPI 1108 without issues.

personally i hate the things.. they only improve airflow by not being as good of a filter.
for the engines life on a whole, you cant beat the oem paper filter. if you want more airflow but still want good filtration, find a way of getting a larger paper filter (bigger air box from another car or a paper filter with more pleats).
