No.. also, Cobb doesn't have an off the shelf map for your intake (that I'm aware of), so you should probably get a Protune if you want to leave it on the car.
Running stage one cobb intake tune no problems works great:)

MAF scaling for the Cobb intake is different than it is for the K&N.. just because it feels like it runs fine doesn't mean it's not causing engine damage while in open loop fueling. I might feel like it works great right up to the point when the engine fails.
