Ive seen setups on here with Velocity stack w/o filter. Filter as in cone filter on velocity stack. Now I know there has to some sort of filter/mesh screen on the intake tube somewhere right? Or are they running the vc open no filter???

 

You're not looking hard enough. K&N makes one.

 

As does comptech/ ct engineering.

People are running stacks with no filters on them, but that doesn't make it good.

 

Other then some Harley mesh screen nothing..

 

This is the intake pipe that feeds my GT3076R. It's a 6" inlet AEM Dry Flow on a aluminum velocity stack with 4" outlet. The pipe is powdercoated in a thermal coating.
