Anyone have any experience using these on our M157 engines? I have used their filters on my '12 CTS-V and it breathed quite a bit better using an Airaid Intake.

I want to pic up a set...The price point is really good also.

 

Anyone....anyone...?

 

If you like it, give it a whirl.

K&N is about $20 more. If you like Green Filters, then go for it.

I personally don't believe that these do anything for our cars, but maybe I'm just stuck in my ways
