K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly.
This intake system drastically improved the sound of my 2013 Cadillac ATS (3.6). Definitely noticed an increase in power. Pretty easy to install,took about 90mins. Really quality parts,definitely recommend!
I like this product fixed it on my 14 ats 3.6 and it added great sound and slight power increase..recommended with cat back as well to get the most out of it..great decision!
