Did any e9x ever have the loo roll breather? I thought it was history before the end of E46 production?

24mm is the red size, its relevant if ordering blanking plugs as some cars have 32mm holes, some have 24mm.
The larger 32mm ones (like my 535d had) have a thicker spindle and the flap itself is different, along with that jacket thingy around them. Still recall my flaps being attached by screws to the spindles. They are less liable to fail IIRC, but I don't know if they are 100% safe.
On the breather you are probably right - the problem was when I got the part number off the top of the casing, I googled it and a forum result said that was the part number for the loo roll type casing, so I just went with it and bought a vortex.
