in an NA application where all you have is the pistons sucking in air velocity stacks become more of an issue an turbo charged where you have the compressor wheel sucking in air its alot different of a story.
The RVM dual pop will work fine for 95% of the people here. Yes the dual pop from JWT with its a bigger filters and velocity stacks is more ideal. But that will only mater to the 5% of users who actually can taken advantage of that need.
