Link to Debaffling mine was already taken off from the previous owner so I can't really help you out too much, but I took off the tube that leads to behind the headlight and there is a noticable volume increase from taking that off B) Having it debaffled doesn't really have any real performance increases just noise which is enough for me. I find myself driving faster in higher RPMs just to hear it.

On the 325i like we've got, the baffle is up inside the top of the airbox where it hooks up to the MAF sensor.

Take out the airbox, look up in the top, you'll see it. Pry the sucker out with a screw driver. It won't fit out the slot, so take a dremil tool and cut a half inch out of the tube with a dremil tool. Then just slip it out. Don't try and pop the airbox in half because it's glued together.

I think I may know what your talking about... I looked all around the airbox and I saw another looking thing up there. If you could explain it a little more that would be great.

MAF= mass air flow sensor. The little thing above the airbox.

Ok Skawful: Debaffling the 325i airbox.

1. Remove the airbox from the car. There's two silver clips on the MAF sensor. Then there is two nuts to the right side of the airbox (when you're facing the windsheld standing at the front of car) There's a duct on the front of the airbox you need to take off, wiggle the rubber tube of the other outlet to the engine.

2. Once you've got the airbox out take a look INSIDE. Up where the outlet to the engine is there's an extra plastic piece. This is the baffle. Stick a screw driver in the seem between it and the rest of the airbox and pop it out.

3. Ok, so now you've got the damn thing out of the airbox right? Well no. Now you realize that there isn't enough room to take the baffle out. The solution is to cut a small gap in the baffle with a dremil tool. Then sneak it out the inside of the airbox. Or you could just it the whole thing into 2 pieces.

4. Reinstall your stuff, you're done.

Kevin

P.S. I let the inlet from the front grill off only because it was sitting on the other side of the car and I didn't see it till I closed the hood ghead

a dremel is a multi purpose rotary tool.

Don't worry, I'll have pics and a video up tomorrow on the process and resulting sound and performance.
