I've done a search and can't seem to get an accurate answer... what are all the differences between the 1st and 2nd gen Magnus intake manifolds? Also, when did the 2nd gen one come out and how do you tell them apart?

Thanks ahead of time for any info...

 

The second version I believe has the velocity stacks in it. The other one is just a tapered cone on each runner (Inside the runner). You could easily tell by looking inside it.
