This genuine Bosch Fuel filter is a drop in replacement for the Rotax supplied fuel filter, same dimensions and threads.
We have used this particular filter model with Rotax 912iS engines for many years - even before Rotax launched their own filter....
We recommend changing the fine fuel filter at first service (about 20 hours) and then at 100 hours/annually if running the Rotax fuel pumps or 200hours/biennially if running with the brushless Andair fuel pumps. We also recommend monitoring fuel pressure BEFORE the fine filter to alert to any debris build up - any pressure above 3.6 bar before the filter may be related to fuel filter fouling. NOTE fuel rail pressure (after the filter) should remain within the Rotax operating values.
