I can't wait to get mine on my car. I still want a Cobb AP but with the added benefits of the JB4 I might just stick with it. I guess its depending on if any problems start once I put more miles on my car. I hope they come up with a Cobb for our 2013 soon. Not holding my breath, hence why I'm buying a JB4 to hold me over.
Bmwbreed, let me know what kind of difference the DP makes. Is your car stock otherwise, exhaust? I was thinking about ordering at least a drop in k&n the same time I drop the jb4 in.
