Just finished installing the K&N CAI on my 2018 Longhorn with 5.7 Hemi. I've already installed the Edge Pulsar Tuner and the new sound is AMAZING. Much more throaty growl at about 2000 rpm. The only issue with the install was the crank case vent hose. The supplied hose was smaller in diameter than the factory tube that had to be trimmed. I got it on but will have to look into a bigger diameter hose. Additionally the elbow fitting for the hose to alleviate kinking was also to large for the supplied hose. The only fitting the hose actually fit was the fitting where the hose connects to the air intake tube. Other than those minor issues, it sounds and runs great.
