Lookin around for a cold air intake and found this
and thought it looks familiar, so I went here
and it looks to me that they are the same. I just don't know the shipping from mac, but would have to be real low to beat ebay price.
Also, wondering if it would make a difference getting the intake above when I have a cone (3.5" inlet) on my moded stock box. The Mac intake looks like a bigger filter........
