Power Filter by WB

[400ex4ever]

Just want some opinions on a PowerFilter made by WB. I had one laying around in my garage when I bought a new E-series for the 400EX. Looks to me like it would flow better then the stock? Getting ready to install the HRC kit next week and thought I could through it on if it was any good. Thanks.

I have one on my 400. Works great, and yes it flows better than stock. I also kept the metal screen insert in it to filter the smaller particles.
