The screen i bought i used once and went back to stock
The group fills that fast esp on a evo, the difference will be negligible.
Nothing is under pressure so it will flow totally different with a puck to an open group
The stock screen is thicker than the ims on the evo but if you give it a slight bend the spring clip holds it tighter,
Of all the things to obsess over this isn’t one of them,
Fwiw the decent screen i got didn’t flow anything like what the media of decent showed.
