Gday STC,
I haven't had any problems with the air filter yet, but it gets extremely dirty with each use and I have read other forums where some people have dusted their engines with the oem filter, though they may not have properly installed or oiled the filter.

Gday Benifur,
I had a look at the motor saver air filters and it is exactly what I was looking for. I see that they have ones that go straight onto the carby, and ones with 60 and 90deg elbows.
Do you know the part number of the one that you used on your Genesis?
