is this the kind of scoop that remains open at all times?

 

I've seen a lot of local vehicles with that set up. The cars seem to run well with it, but I have never ran one myself. I think they can really make a car look mean when done right.

 

I bet the real ones that sit on top of a top fuel funny car work as designed but,
this one says "
Get that competition look for less.

There's no better way to top off your street machine than with one of our Summit® Street Scoops. These scoops give you that classic Top Fuel and Funny Car look with a polished or black aluminum body, matching bezel and inlet screen, a filter element, and mounting hardware. They're available in both dual quad and single quad styles with plain or finned tops. "

It has the look but the functionallity and performance might not be really be there.
600 sccm? Sounds like a small block app? 2 dual quads on any V8 is cool though.
That looks like they are just for show.
The demensions are 20x12.5x4? I don't know. That would look cheesy.
Summit has a great return policy if you don't like it.
You did ask for an opinon.
Good luck with that....
