Is there any particular reason why you don't want the aem intake
(video of it on an Alero)? I think you can get a knockoff of this intake on ebay for dirt cheap, if you don't mind buying cheap parts. If you still wanna move the battery, get a relocation kit for like $40 from summitracing.com. Then it will be in your trunk and help to even out your weight distribution a little bit. With the AEM intake, there will be no need to relocate the battery though.
