are obx intake manifolds a good product for the z24's and does it improve power?

it has fitment issues

its an extremely cheap rip off of the venom intake manifold and complete junk as far as im concerned. it has sealing issues up against the head. clearance issues with the throttle body. it also does not have the channeling system in the flange for the PCV hole in the head like stock and venom do.

a buddy of mine was well into the 14's with a 75 shot with the stock manifold, put the OBX on and couldn't get past a 15.5 with a 75 shot.

i have seen pics of them, and they are a cheap imitation. perhaps a good building block, but it is going to require a lot of re-work to perform properly.
