Anyone Swiss cheese an E36 M42 airbox?

This sounds so intriguing. I have heard of it before, but never looked into it.

Even if only for sound improvement, I'd still do it.

Fog your airbox.

That is for M44 motors.

They have an entirely different intake setup than the M42 cars IIRC.

Where is the beat head against a wall smiley when you need it.

Well I finally got around to trying this today....

No real noticeable effect. Sounds a little different and stuff, but to be honest, I was only really driving around the neighborhood so I couldn't really get on it fully.

I had my dad drive past me, and it did sound different than before, but I will be able to tell at the next auto-x when I am watching one of my bros drive the car.

NOTE: I drilled 72 total holes. A few on the front area, a few next to that on the side, and the rest al along the side in the middle and towards the top.

And I also didn't use a huge drill bit...didn't want to make the holes too large.
