Superchips Performance Tune and K&N FIPK

[Seraphitia102]

I just recently got the Superchips Microtuner and it's amazing in terms of horsepower, and ride quality except when shifting into 4th gear, in which it becomes such a hard shift. I just got a K&N FIPK installed as well a few days later, and my shifting is smoother even on 4th (auto). Is it possible that a cold air intake makes shifting and drivability even better or am I just feeling things? My car is also a bit louder, does that have to do with "more air in, more air out?"

When I took out the silencer and put in a K&N drop-in on my GT, it made the exhaust a wee bit louder and I could hear a lot more intake noise.

Now about the shift firmness, this isn't relevant to a CAI so my guess is you're feeling things.
