Airbox Warning


Recommended Posts


Just a heads up for anybody with hidden air filters.

This is what i found when checking the hidden airfilter on my m25y .

I have 2 of these motors one with 50 hours and on with 10 . They are both the same age and both had the broken up filter which was ingested into the engine.

Its ironic that the air filter itself created a filter problem.


This allows the degraded air filter element  to be sucked into the engine bit by bit. The trouble is that it is not easily visible and i only found it by accident.


It may be common to other air boxes

I replaced it with a more simple filter  as pictured .

other than this problem these engines seem flawless.
