Does the green filter help?

I did back to back tests a while ago, like I said the difference was subtle but there. Also if you follow the C7Z forum, those guys are making large gains from replacing the filter.
With our supercharger kit the difference was also very noticeable on the dyno.
On a base C7 it's a small gain for a small price, whether that's worth or not is up to you.

All oiled cotton gauze filters are very similar in terms of flow and filtering ability. AFE is my personal favorite, but I've also used K&N's in a lot of applications, and is what I put in my father's C6 for him due to cost vs. others. I have no personal experience with Airaid or Green, but from what I know they're similar to both AFE and K&N (only so many ways to reinvent the wheel).

You can use either if you plan to not use a restrictor plate with our kit. (700 rwhp) If you do plan to use the restrictor plate then the filter we use is specifically made to hold it in place.

ECS' Green: For use with or without restrictor plate.
From what Doug has said, I take it the Green air filter they offer is different than the regular Green filter sold elsewhere.

Exactly! And the guy starts with a great post question about the Green filter then as usual it diverts to anther type in this case the K & N. Owners hardly ever seem to be concerned about small particulate matter passing through the filter and then into the engine, only about flow and HP gains. Any filter that allows more flow also allows more unwanted matter into the intake. I will stay with frequent and clean C7 OEM filter changes rather than the Green in question here or any other type.
