It also runs a tad leaner on the R2Cs. I did a few 0-60 runs today and for the first time (after the Cobb tune and with the R2Cs on) I chirped the tires in 2nd gear (with A/T) - never happened to me before, so maybe I did add a few HP, who knows.

Yea the big filters probably dont need to be that big, the car can only suck in so much air regardless how big the filters are, I did an air intaake reading on my Cobb and was getting like 400 GS at WOT and I dont think the car can suck in any more than that and the K&N filters can flow way more than that. The Cobb tune should have fixed your AF so its not too lean.
