I have never had an issue with a CAI on any vehicle I have ever owned. The last two I have purchased have been roto-fabs for my 18 Camaro and 19 Silverado both 6.2. Speaking about the truck system it really cleans up the engine bay. Noise didn’t increase that much has a nice growl when you get into it. Definitely seat of the pants it feels more responsive/powerful. No numbers to backup. Mileage was up at first but as of late I have been getting on it more and it has settled back to where it was 17-18 daily. Ryan B.
