You didn’t add a cai you just replaced the existing one with an aftermarket one to no gains. The stock intake is already a cai.I have a 2020 5.7 engine and I went with the Magnaflow. I liked the nice rumble without being over the top load. The one thing I will warn is you really are not going to gain much performance. You are basically paying $1,200 to sound cool. I also added a CAI and again there was not a noticeable amount of performance gain not increase in fuel economy.
