right.... and how do i fix it if they do snap, or is the best thing say... drilling out?
The housing is plastic with threaded inserts. You;ll need to be careful to save the inserts unless you can find something else to fix in there.
Judging by the state of my air filter I don't think it ever got changed in the first 70K+ miles of use (and always serviced by Alfa!!!). But I was careful when turning the bolts, used lots of PlusGas and got all three out ... they were about 5-6 years old then.
