Review on High Performance K&N Cold Air Intake Kit: Guaranteed Horsepower Increase for 2018-2020 Jeep (Wrangler JL, Gladiator) 3.6L V6, Model 63-1576 by Ryan Lawson

I installed it today and it took about an hour. It would have been quicker, but I walked in and out of the house, grabbing tools and coffee. Good.1. Installation is easy if you have the right tools and read the instructions. There are videos on Youtube. So if you need more instructions just google the Jeep Gladiator K&N Cold Air Intake Install.2. The engine growls when you step on the accelerator! I don't want the full sound of the secondary exhaust, but the stock intake makes no noise at all. If you're looking for a comfortable growl without being obnoxious (IMHO), this is the way to go.3. Throttle response is noticeably better, but I'm not sure how much that has to do with the sound, maybe a Jedi mind trick. This is handmade in the USA!1 (according to packaging)Bad.1. Other brands do not require you to remove the grille and remove the rear air intake pipe. It's not a big deal if you're familiar with grille removal, but it still increases installation time.2. I've had other cars with CAI and sometimes they feel sluggish at low rpm. Overall they add HP and I think they're worth it, but it's something to keep in mind. I still rate it 5 stars despite these very minor issues.
