ATS-4 Intro
 

Hello,
New to the Cadillac brand. Bought a 1 owner 2014 ATS-4, 3.6L, about a year ago as a nice commuter car. I was surprised by the factory performance and would like to add more performance.
Plan to research the "Free Mods", and low cost like adding a K&N air filter. I plan on getting my hands on a throttle body to port and polish.

Would welcome pointers on posts to read.

Thanks!
