Has anyone tested/ tried those new air filters from R2C/ DMC? I am changing my filter out and was going to try this one out. I recently had my top end rebuilt, and added the Double down intake with the super seal gasket kit to try and keep sand/ dirt out of the motor. I seem to still be getting some dirt in the intake boots and was going to try this air filter out, since it has a bigger lip and is supposedly serviceable.

Just wanted to see what others thoughts on the filter is?
