Who has a replacement pipe for that baffle filled air box?

Roto-Fab and New Era Performance are the two major ones that come to mind. If you do a quick search in the performance section I'm sure you will come up with some hits.

We are working with another vendor right now on a 4 inch MAF sensor also , testing has already been done with our intake on a Stock G8GT and there was a 4 rwhp gain , but tuning is mandatory for this , or your car will barely run . Pricing and availability will be announced soon on this .
