Eddy airgap intakes?

I have one of the Professional Products Crosswind Air Gap knock offs on my 360. On the few cold mornings (high 20's low 30's) it has taken about 4 to 5 miles for everything to warm up and be totally happy. Other than that I can't imagine what you could improve upon for a daily driver.

But, like others have said if you have a manifold i don't know if I would go out and invest in abother one.
