Really Breathes, but not a quick install.
Once installed, you really hear it sucking air. Does the job it's supposed to do. The install was a pain on the cavalier I installed it in. Would have been much easier if I would have removed headlight housing and bumper skin. If you don't remove those two parts your working totally blind with next to no room to even work a ratchet wrench. Was surprised it didn't come with all necessary clamps. Also did not come with heat shield shown in description. Descent product.
