Air filter change

[trobex]

I got a Mahle spare. I pulled my old one out and it nearly looked new...

a curiosity about the air filter: what is this appendix for?

Could it house the mass air flow sensor (MAF)?

Isn't MAFs your favourite show?

It acts as a muffler to quiet intake sound

 

[Commodore]

Thought I would post a confirmed figment and a great price for an air filter. As others have noted the factory filter is a BMW part number 13718635102. I found the Febi Bilstein brand at RM European on sale for $7.11 so I purchased two of them.

Most likely a resonance/expansion chamber to help tune impulses in the intake tract to help quiet it down or possibly eliminate unwanted turbulence of the airflow to help the air move more smoothly through the intake increasing efficiency slightly.

Thanks, I had never heard of it.
I can’t find the intake resonator delete for Ineos. Where can i find them?

Two things to add to this:

1) there are six screws on the housing that need to be loosened to lift it (two on the side of the engine were hard to see standing on the ground).

2) when I lifted my old filter out there was a foam pad that is connected to the floor of the housing. Does this need to be replaced too? It is screwed in, unlike the photos in the original post.

here is one but others make them

BMS Intake Muffler Delete

The BMS Intake Muffler Delete easily removes the bulky factory intake muffler (resonator) for better sound and cleaner looks under the hood.

Does it make much of a difference in sound?

Does it make much of a difference in sound?

For me (with a RAI), almost no difference

 

[ORSO]

no,

Does it make much of a difference in sound?

I didn't notice any differences with the RAI

Thanks for sharing! To me that looks like a clean filter. Smack it off and hit the fuzz with a vacuum and reinstall.

How was shipping costs? It makes you enter a CC before seeing that, so just curious (approximate). Thanks!
