Homemade Alum. Airbox??

[Drtridr18]

Doesn't some company make aluminum airboxes with a bigger volume and enough space to relocate the battery in there? And it's expensive i bet too.

I'm pretty sure i've heard of a couple of you guys that have built your own, and i'd like to do that also, i'm a machinist and have access to the tig welder whenever, but i'd like ideas or plans if anybody has some input...hook me up??

Thanks a lot
