Air filer for E90 320d

[Gunner-Win]

Hey guys,

So my E90 320d LCI has just gone out of motorplan. I will now be doing services myself, and in the spirit of saving money I was thinking of going for a K&N or BMC air filter, as these are lifetime filters that can be cleaned and re-used.

It's more a cost saving thing than a performance mod.

So I have a few questions, and would appreciate your guys input if possible:

- Should I go for the K&N/BMC filter instead of an OEM replacement?
- Does anyone know where I can get one from? I see Autostyle stock for the Z4, the E90 335i, and "BMW E90 4 cylinder". Do any of these fit in my airbox?
- Has anyone done this before? If so, was there any noticeable difference in the air flow rates, or performance figures?

I'm based in JHB btw.

Thanks in advance for the help guys.

Yes both my 320d's and my 330d have had a k&n. You won't notice a difference. Auto style can get you the correct filter. But that 4 cylinder one they mention is for a petrol, I know because I once ordered it and they switched it to the diesel one for no extra charge.
