Dinan Filters

jclaib · 05-04-2023, 06:51 PM

At 3:05 in this video, what is the white filter behind the factory filter? Is that a carbon or OPF filter? Looks like they would be removable if in fact I have them on my car. More flow?

charcoal filters that can be removed. OPF is in exhaust, not intake

So they CAN be removed. Any thoughts on SHOULD they be removed? Seems like their absence would free up some airflow.

I think a lot of folk remove them without ill effect...should? I have no clue

I feel like I’m always commenting on posts after dmanb2b…lol

They can be pretty easily removed with proper force from a screwdriver. The X3/4 M technical documents on the board specify that they should NOT be removed, yet they’re supposed to be replaced at service intervals?? And IIRC they’re like $100 to replace. Makes no sense to me. Just take em out. Better yet, get a RKTunes or BMS intake so you can really hear the turbos

When I had the stock intake I had removed them. Did feel a pep in a throttle response for sure (positive).

Removing the carbon filters on the intake of my f90m5 resulted in a bit more induction noise ( a welcome change). The f97 may have a similar result and I intend to remove them when i change my filters soon

Btw Rest of the world cars don't have these carbon filters - it's a USA emissions thing.

Installing the Dinan filters and removing the carbon filters tomorrow.

Does anyone know the lug torque settings for the strut brace bolts?

The strut bar nuts should be 30nm (right around 22 lbft).

I completed the carbon filter removal and Dinan filter swap this morning and went for a short joy ride. I also have the Dinan X Pipe installed.

Definitely a but more growl to the engine and some induction noise. And no noticeable turbo noise, which is good for me. I don't care for it.

The throttle feels a bit punchier in the mid range. All in all a good mod and it took me about 20 minutes to do.
