has anyone completely removed the plastic cover beyond the air filters that the burger motorsports filters replace? i know the side opposite of the brake reservoir is electronics... is that box sealed pretty good, or does it need that other cover? i took it off the other week while messing with the strut braces and it seemed kinda lame. i'd like to get rid of it all together, but the front end of my car is becoming more and more inviting to water.

So my generic response would be this: BMW puts that plastic cover there for a reason. I'm not accusing you of this, but sometimes I get the sense from owners on forums that they assume OEMs are staffed with complete retards who don't know what they're doing. Every piece is carefully designed and tested, and serves a specific purpose.


Sometimes that purpose is one that isn't particularly important to an owner, especially one who is using the car on a race track. Other times it is critical to safety or basic operation of the car. Best example I can come up with right now is the belly pan. There are so many people who kept parroting the idea that it's stupid and you should just remove it -- yet it is critical to managing airflow under the hood AND to protect belts and other parts of the engine from debris.




That being said, my gut tells me those plastic parts are partially for NVH in the cabin, but largely to provide additional barriers for water and debris, and potentially engine heat. You could probably test this pretty easily with a quick test drive.

right. i'm in the same mindset, thats why i'm being critical of my urge to take it off. more air flow out of the "cowl" area.
there are so many people running around with beat to shit undertrays that when someone posts up about their warm track temps i'm always asking "hows your undertray looking?"
i'm sort of thinking its just there to cover the ugly stuff and cover the transition into the windshield.
i know dogbone doesn't run his, but he is car is trailer kept and only sees track days.

It might also be protecting the edge of the windshield and directing air for proper aerodynamics + windshield wiper operation.

Plus without it you will be pulling unfiltered air into the cabin / HVAC. I decided to leave mine in place for filtration and to protect everything beneath it.

I have the burger tuning filters... I'll have to look carefully, but does the secondary cover cap anything else?

The burger tuning filters attach to the secondary cover. Without the secondary cover there's nothing for a filter to attach to. It's just a wide open cavity. Take it off and you'll see. Water flowing down the windshield will go into places you don't want it to go. I explored this but I would not consider removing it on a car that is anything but a track car.

roast,
Can you share some more insights into these filters? And specifically what you give up by using them?

I understand the benefits (remove 10 Lbs weight and more engine noise in the cabin) but what else?

Just gets rid of the big charcoal cabin filters. It's like 5lbs. Easy access to the brake fluid, too.

oh.
So the issue at hand about it plastic cover that you misplaced it, or you can't find away to install it?

Better yet, can someone post picture in the secondary plastic cover in question

I don't see temp

Here are all the things the AiM BMW ecu can report on. Click on the picture to see the top. The one with the ECU is page 1. The one that starts with "MIL" is page 2.

AIM does not decode IAT on the BMW CAN bus. You get ambient air temps, coolant temps and oil temps. They have DCT temp listed as an option but it does not work....yet.

Brake pad wear question.. I had some significant tapering of my pads after some 2 days at laguna seca and 1 day at Sonoma. When I pulled them out one side was tapered down to nearly backing plate while the other side was still as thick as the backing plate.

Is this a cause for concern? Prior pads wore much more evenly. Could it be a sign of needing caliper/piston rebuild? I am running a 380mm/ 6 piston kit up front and also BBK in rear. Have run about 20-24 track days with the BBK so far and bought it lightly used

Let me guess, inner front passenger side is the most worn?
