BMW E46 330i ZHP AFE DAS (Dual Air Scoop) DIY doityourself

I was thinking of doing that also. Just not sure which color to go with. Plus if you don't like it, you can always go back!

I wonder if there are any *actual* gains in this..

I'm sure it won't hurt at highway speeds...but I rarely travel at highway speeds.

I think the scoop can provide colder air into the air intake and prevent sucking hot air in. I was thinking about cutting the driver side brake airduct inlet next to the fog light to suck in more cold air into the bottom of the AFE housing. And put a plastic cover to cover the hole in the rainy day. Sound like my silly mod :P

you won't feel a thing. had these on my 328 E90 - good in theory but they really don't do anything unless you're hitting like 150mph. even at 70mph the benefit is marginal.

looks cool though.
