Not to downgrade the Akimoto Sports filter, but I have on sitting in my garage
that we did a smoke test on. The inverted "Velocity" tip did nothing but
restrict the flow. The K&N 6"x9" cone and the Akimoto both pulled air in from
the base (largest area) first. K&N has also stated (on numberous occasions)
that the inverted cone filters don't flow as well as the regular cones. This
confirmed our smoke test on the Akimoto Racing filter that I have.
I've had it for a little over two years and used it on my truck as well on the
old "Home-Brew" system. After replacing the Akimoto with the 6x9 cone, the
truck performed much better on the top end. Yes, I even tried this with the
current configuration (Powerdyne @ 9# Boost) and again, the K&N 6x9 cone
performed better.
Here's the fomula for CFM for the cone filters:
(((Largest Diameter + Smallest Diameter)/2) * Actual Length) * 18.84
(The 18.84 is PI*6)
That's my experience with these filters and my opinion.
