Does anyone know who's makes this plenum ?

Does anyone know who's makes this plenum? All I know is that's it's polished. I haven't measured the opening yet. Here are some pictures.

Opening is 2 3/4 inches.

Yep, looks just like mine. 70mm Precision Turbo & Engine, PTE or Presision for short.
Get an RJC Racing Air Distribution Power Plate to even out the airflow to all cylinders and you're golden.

Not sure but I think that PTE, Accufab and Kenne-Bell are the same …right?

no they are different
the pte is taller has an angled back mount for the throttle body and has a raised mount at the throttle bracket bolt , it uses its own rjc powerplate,
kenne-bell/accufab are shorter and throttle body bolts up almost level , rjc makes a different plate for it than the pte. the kenne bell would have their name engraved on top by the throttle body

most of the plenums are 70mm but also could be had in 65mm o as accufab made a 65mm throttlebody

Just looked at mine. I have a PTE and it only has 4 raised ribs. The one pictures has 5.

Good catch, thank you for the clarification.

Thanks Paul for explaining. But I must say that some pictures would really help identifying them…
Performance-wise, is there one better than the others? Right now, I have a Champion intake manifold which when I bought it came with it's own plenum.

Check out rjcracing.com as they have Air Distribution Power Plates for Champion plenums.
Of the data they have listed on their website, the Presision plenum w/ power plate is the most even. You will have to call to see how the Champion plenum w/ power plate compares as the data is not listed.
