Roto-Fab 10161061 Cold Air Intake System for Cadillac CTS-V 2016-2019
Not an upgrade you're likely to regret. The Rotofab air-intake system was easy to install, and now the car pulls harder on the highway handling.
AEM 21-849DS Cold Air Intake System
The AEM 21-849DS is a bolt-in cold air intake that increases horsepower and torque and improves engine sound. It is not a free-flowing cold air intake, so it doesn't provide as much cold air intake as the cheapest upgrade we tested, the Edge Products Cold Air Intake Filter.

This CAI uses stock intake tubes, so installation is very straightforward. At no additional cost, AEM's CAI includes a pre-oiled air filter and a heat shield.

This intake system didn't boost our stock engine's performance, but it added 2 hp. And its smooth sound really impressed us.
Airaid Cold Air Intake System: Increased Horsepower
At half the price of our winner, AIRAID's intake system doesn't do too badly in terms sound and performance. It's missing a few key features, however, such as extra filters or a mounting kit.
