jumping on the band wagon here....
+1 on what all these guys said as well....complete JUNK.
the Bullit Intake, Hardballr intake, and Foxlake's P51 are good manifolds. i've heard that Trickflow's new one was good as well....not so much in the n/a part of it unless highly modded, but on FI thats when it really shines. Basically a knock off of the bullit intake (probably small differences, not to sure, but its pretty obvious where the design is from...)
but yeah go with what these guys are recommending kolby
